i-rinat / apulse Goto Github PK

Привет, Ринат!
У меня опять проблемы со скайпом и с переменной окружения APULSE_PLAYBACK_DEVICE="plughw:0,0".
При загрузке скайпа с этой переменной
LD_LIBRARY_PATH='/usr/lib/apulse' APULSE_CAPTURE_DEVICE="plughw:0,0" APULSE_PLAYBACK_DEVICE="plughw:0,0" skype
получаю эти уведомления

[apulse] [error] do_connect_pcm, snd_pcm_open, Устройство или ресурс занято
[apulse] [error] do_connect_pcm, snd_pcm_open, Устройство или ресурс занято

При этом сам скайп видит pulse-сервер но не издаёт ни звука.
При этом при дозвоне на echo123 наглухо виснет.

При загрузке скайпа без этой переменной.
LD_LIBRARY_PATH='/usr/lib/apulse' APULSE_CAPTURE_DEVICE="plughw:0,0" skype
Скайп работает условно нормально. (Раньше без неё у меня звук пропадал при разговоре, сейчас пока проверить это не могу.)

При этом я отключил всё, что может захватывать звуковуху, включая mpd, разве-что кроме KDE, в мультимедийных настройках которого, как и раньше, указан Gstreamer-овский default.

Ещё у меня установлен эквалайзер alsaequal и в ~/.asound

ctl.equal {
	type equal;
}

pcm.plugequal {
	type equal;
	slave.pcm "plug:dmix";
}

pcm.equal {
	type plug;
	slave.pcm plugequal;
}

Пробовал переименовать файл и запускать skype, но результат тот же, да и раньше это проблем не вызывало.

В чём может быть проблема? Куда копать и что можно поставить в APULSE_PLAYBACK_DEVICE вместо plughw:0,0?

Mozilla decided to deprecate alsa support from firefox 52.
I used arch linux aur apulse-git[1] package, and tested with firefox-52.0-1 .

[2] was used to test things, and apulse-git succesfully made firefox believe pulseaudio was present.
Every test succeeded.

I intend to install apulse on several other AL systems i help maintain, but convincing the owners would be easier with a recent stable release.

Thank you for this program.

[2] https://hpr.dogphilosophy.net/test/

Add echo cancellation to apulse. From webrtc, or from speex, for example.

With Firefox 52+ dropping ALSA, thank you so much for this! This might be the only way to still use Firefox with ALSA.

hi
I have an amd64 gentoo system. I have never installed pulseaudio. I have install apulse, and skype is working back again (thanks a lot!). but since google-chrome is mute! firefox, vlc, everything else works, except google-chrome. Could it be because somehow google-chrome believes that I have pulseaudio installed?
any suggestion to fix that?

here is the new error message that popups each time I read a sound in google-chrome
ERROR:audio_manager_base.cc(250)] Invalid audio output parameters received; using fake audio path. Channels: 2, Sample Rate: 0, Bits Per Sample: 16, Frames Per Buffer: 1024

and obviously i'm not the only one ...
http://forums.gentoo.org/viewtopic-p-7649684.html

I would like to point out that identifiers like "APULSE__TRACE_H" and "APULSE__UTIL_H" do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

Thanks for this project that permit us to get rid of pulseaudio to use Skype.

The only way I get to use apulse with skype is using this .asoundrc:

pcm.duplex {
    type asym
    playback.pcm "dmix"
    capture.pcm "dsnoop"
}
pcm.!default {
    type plug
    slave.pcm "duplex"
}

That works using the Echo/Sound test of skype but that don't work for long in real call:
it works for few minutes and suddenly, no sound is hearing anymore by my voice call mate.

The fact that I use a real audio card with hardware mixing so I don't need dsnoop/dmix combo.
And last point my default output is hw:0,0 but my microphone capture is on hw:0,1.

How can I tell a pulse to use hw0,0 and hw0,1 as respectively my playback/capture device ?

Hi there,

i installed apulse to get Skype working on Arch-Linux. But somehow i cant get it working. In the Skype Option Menu the Speakers "Virtual Device" is listed. But neither the testsound or a testcall work.

Also with the command "APULSE_PLAYBACK_DEVICE=hw:0,0 skype" i cant get it working. My "aplay -l" output is:

[indy@WinArch ~]$ aplay -l

Spotify 1.x requires pulseaudio. With apulse one can get sound, but it is choppy and too fast:

Skype works well for me in that I can make the standard test call and hear myself back. However, if somebody calls me, and I click to answer, that window disappears but I still hear the ringing and see,

[apulse] [error] do_connect_pcm, snd_pcm_open, Device or resource busy
[apulse] [error] do_connect_pcm, snd_pcm_open, Device or resource busy

I am using the v0.1.5 tag, invoked with,

$ APULSE_CAPTURE_DEVICE=plughw:1,0,0 APULSE_PLAYBACK_DEVICE=plughw:1,0,0 schroot apulse skype

My Skype is 4.3.0.37 under a 32-bit chroot.

Using Firefox 52 with apulse 0.1.9 and the dmix ALSA 1.1.3 plugin, Firefox can play audio from multiple tabs simultaneously and it works great.

When playing audio in multiple tabs, each tab gets a mute button. With direct ALSA+dmix in Firefox 51, this worked well, and tabs could be muted individually. With apulse, however, pressing "mute" on one tab is muting them all.

When I disable dmix, Firefox+apulse can't play multiple tabs simultaneously, so mixing is happening at ALSA level, so I assume apulse is sending separate streams for each tab via ALSA. I note also that the device does not get muted, so I believe apulse is muting "via software" (ie, not sending a mute command to the actual device).

This is my ~/.asoundrc to get software mixing via dmix working (but I have no reason to assume the same issue isn't happening with cards that do hardware mixing)

pcm.!default {
   type plug
   slave.pcm "dmix"
}
pcm.dmix  {
    type dmix
    ipc_key 1024
    slave {
      pcm "hw:0,0"
      period_time 0
      period_size 1024
      buffer_size 8192
   }
   bindings {
      0 0
      1 1
   }
}
ctl.dmix {
   type hw
   card 0
}
ctl.!default {
   type hw
   card 0
}

Thank you for apulse, it has become an essential tool in my system!

I have two audio devices. The first one is a builtin IntelHDA sound card and the second one is a USB microphone. This setup will only work if I have a specially crafted .asoundrc. Here it is:

pcm.logitech
{
    type hw
    card LogitechUSB
}

pcm.usb
{
    type dsnoop
    ipc_key 234884
    ipc_perm 0666
    ipc_gid audio
    slave {
        pcm logitech
    }
}

pcm.!default
{
    type asym
    playback.pcm
    {
        type plug
        slave.pcm "dmix"
    }
    capture.pcm
    {
        type plug
        slave.pcm "usb"
    }
}

This file makes my USB microphone the default recording device. The problem with this set up is that Skype record ~0.5 seconds of audio and then fails.

It can be easily reproduced this way. Run this command, it will work:

$ apulse ffmpeg -f pulse -i default /tmp/pulse.wav

Now run it again (it will ask to overwrite the existing file), and ffmpeg will stall after recording exactly 51,278 bytes of audio. It seems like apulse fails when a recording device is routed via dsnoop and it's quickly reopened.

I have this weird problem with skype, after some time in a conversation microphone just stops working. It could be anything from 30 minutes to 2 hours. I don't know what other information I need to provide at the moment.

apulse-operation.c:66 -- looks like a copy-paste error from the previous line, should array subscript be 1?

Hi and thank you for a great piece of software allowing us to run skype without pulseaudio on 0Linux,

your cmake file does not allow one to respect an alternate suffix for libdir. Could you add one ? Typically, projects usually provide a -DLIB_SUFFIX="suffix" extra paramater to allow to install in a /usr/lib64 dir, for example.

Moreover, this is quite needed in a mulitlib environment (like 0Linux has). So for now I have to move libs in a temp dir then replace them at each build (I need a 32-bit build and a 64-bit one into the same package).
See: https://github.com/0linux/0linux/blob/master/0Linux/a/apulse/apulse.recette

Thanks!

Skype play sounds ok, but microphone doesn't work in skype at all. While skype test call (echo123) when it tries to play back my recording instead of 10 second (of silence) I get only about 0.5-1 sec between before/after "beeps", which gives me idea it may be related to wrong sample rate.

I've this issue with apulse 0.1.2, 0.1.3 and dev branch.
My system is 64-bit Gentoo Linux, skype-4.3.0.37, sound card SB Audigy 2 ZS [SB0350].
Skype is 32-bit, so I'm running /usr/bin/i686-pc-linux-gnu-apulse skype.
I've tried without ~/.asoundrc and with ~/.asoundrc from issue #14.
I've also tried APULSE_CAPTURE_DEVICE=plughw:0,0 /usr/bin/i686-pc-linux-gnu-apulse skype.

Testing microphone with arecord/aplay and alsamixer show everything is fine (mic volume is ok, wav file recorded and played correctly). With pulseaudio microphone in skype also works ok.

Apulse with Skype works perfectly until I put the computer to sleep (S3). When it wakes up, Skype returns:

[apulse] [error] do_connect_pcm, snd_pcm_open, Device or resource busy
[apulse] [error] do_connect_pcm, snd_pcm_open, Device or resource busy

My ~/.asoundrc is very simple:

pcm.!default {
         type asym
         playback.pcm {
                 type plug
                 slave.pcm "dmix:2,0"
         }
         capture.pcm {
                 type plug
                 slave.pcm "dsnoop:0,0"
         }
}

And I start Skype with the following line:

APULSE_PLAYBACK_DEVICE=plughw:2,0 APULSE_CAPTURE_DEVICE=plughw:0,0 /usr/local/bin/apulse /usr/local/skype/skype

So, any hints?

Ps: when this happens, I have to reboot again to make Skype work again.

I have looked at a few source files for your current software. I have noticed that some checks for return codes are missing.

Would you like to add more error handling for return values from functions like the following?

• pthread_create ⇒ pa_threaded_mainloop_start
• strdup ⇒ pa_stream_set_name

When compiling "32-bit binaries on 64-bit machine" option, we have 32-bit binaries in /usr/lib64 folder:

wiselord lib # file /usr/lib64/apulse/libpulse.so.0
/usr/lib64/apulse/libpulse.so.0: ELF 32-bit LSB shared object, Intel 80386...,

because /usr/lib is usually just a link to /usr/lib64.

Maybe it'd be better to place apulse libraries to /usr/lib32/apulse by default when "CFLAGS=-m32" is used?

Also this can allow to compile both 32/64 apulse binaries at the same time

The lag is small and thus hard to measure and prove, but looks like at least two people noticed it, so I decide to open issue here anyway - either @i-rinat may have an idea how to debug/fix it or more people will notice it too and report here more details which may helps fixing it.

I don't know if the problem is with Firefox (as it has similar problems on Windows), but I thought I'd try here first.

I tend leave Firefox open for long periods of time. I find that, when I come back after a long period (12 hours or more) and then load a video, the audio is all glitchy and stuttery, as if there is not enough memory and it is having to cache to disk. But my I don't use a swap partition on my Linux distro, so that's not it. I also hear similar problems when a process is running the CPU at 100%, but that is also not the case with this bug.

The Windows issue I mention earlier often clears up as the video continues playing. But, with this bug, only restarting Firefox works to fix it.

If I have left Firefox on a particular video tab, sometimes that video's audio is fine. But any other videos (whether from another tab or loading from somewhere else) is quite glitchy sounding.

So, tl;dr version: Firefox (52.0.2) audio stutters really badly on videos if I have left Firefox open for a long period of time (>12 hours). Restarting Firefox fixes the problem.

The stuttering is similar to what happens when the CPU is overtaxed, or when the computer is running out of memory, but neither is the case for this bug.

open("/dev/snd/controlC0", O_RDWR) is blocked by sandbox. workaround: set security.sandbox.content.write_path_whitelist to /dev/snd/controlC0,/dev/snd/pcmC0D0p.

possible things to do in apulse:

1. pre-initialize ALSA before forking?
2. hackaround the sandbox
3. print better error messages (if possible), document this issue

Maybe "program_name"?

I am using a Logitech USB webcam with integrated microphone. Before the pulse-only update I had no Problems running Skype. Now I tried the apulse emulator and the recorded sound is way to fast. It seems this is a know bug with pulseaudio and Logitech webcams (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/843431), but for a workaround one has to set the default-sample-rate in the pulse daemon. I tried to set the sample rate in asoundrc but it did not work.
Is there a solution with apulse possible?

After the next update openSUSE Tumbleweed apulse no longer be build. (glib-2.48 and alsa-1.1.1)

The call to snd_pcm_hw_params_set_channels in do_connect_pcm may fail, it should probably be replaced by one of it's alternatives, or at least just not abort if it fails.

Rinat,

Please remove this "Project is in stale state since its proclamation. The main objective, working Skype test call, is reached. I don't have any plans for further development."

It frightens people. Apulse works better than you make it look.

Thank you.

Mozilla developers have lost their mind and made pulseaudio mandatory in Firefox 52. ALSA support was completely removed.

The test page: https://hpr.dogphilosophy.net/test/

I'm running the git master release (840792f).
Apulse and Firefox are native x86-64 binaries.
Firefox is from: https://ftp.mozilla.org/pub/firefox/releases/52.0/linux-x86_64-EME-free/en-US/firefox-52.0.tar.bz2
Distro: Fedora 25, 64.

When adding an input or output source from pulseaudio in obs-studio, the whole thing segfaults. A simple test with ffmpeg recording works fine, so I can confirm my setup is properly configured. Trace information shows all this:

I'm not really very experienced with all this so I can't really tell what the source of the problem could be. All I see is that line 131 in apulse-operation.c is dereferencing a null pointer.

I suppose this is because it wants glib-2.0 and asound compiled as i386. However, Debian won't let me install them alongside the amd64 versions.

I'm not sure if it's even possible but it would be neat for a little system I have that has working alsa but not quite enough power to run pulseaudio. Was hoping I could just pipe audio to it with the tcp part of pulseaudio.

Some parameters (like "${CMAKE_CURRENT_BINARY_DIR}/apulse") are passed to CMake commands in your build scripts without enclosing them by quotation marks. I see that these places will result in build difficulties if the contents of the used variables will contain special characters like semicolons.

I would recommend to apply advices from a wiki article.

I'm trying to compile 32 bit version to run skype without active pulseaudio.
I'm not familiar with cmake, so I cannot find what is wrong.
Looks like linker cannot find 32bit libraries, but they are present, and ldconfig -p shows them too.

Hello Rinat,

First of all thank you for your job and this software.

I'm curious why you bundled pulseaudio headers instead of to require pulseaudio development files as build dependency. In Debian/Ubuntu we have libpulse-dev package (seems this package have all headers you needed), all others have similar.

P.S. I'm trying to package your software and upload it to official Debian repository.

gdb:

#0  __strlen_sse2_bsf () at ../sysdeps/i386/i686/multiarch/strlen-sse2-bsf.S:50
#1  0xf7b0e12e in al_string_copy_cstr () from ./libopenal-eon.so.1

#6  0x0816f82c in ?? ()
#7  0x00f2f330 in ?? ()

I guess ALCpulsePlayback_ALCbackend_open gets a NULL pointer from apulse, I try to find out which function is called before that crash

apulse fooprogram "bar baz"

will call fooprogram with two arguments, bar and baz, instead of one bar baz with a space in the middle.

apulse(.template) should use different APULSEPATH on "true" multilib systems, i.e.

"/usr/lib/apulse" for skype and "/usr/lib64/apulse" for other apps

Hi!

Thank you for making apulse!

I use a pure ALSA/JACK- system for professional A/V-production without Pulseaudio basing on Ubuntu 14.04/Linux Mint 17.3 with MATE-Desktop, 64bit: ( http://mayastudio.tumblr.com/64bit , http://qianastudio.tumblr.com )

Normally i feel really good with this - but to use skype i tried to get apulse with your little install-guide from page working, but i get following error-message while building:

Fact is that i have libglib2.0 and alsa installed - so i don't know how to handle with this error!
I read in another issue-report here, that is a "new" problem with glib?!?

Also i need the 32bit-install in usr/lib for skype.

So what to do? Is there an easy way to build apulse in 32bit on a 64bit Ubuntu/LinuxMint in 2017!?

cmake, build-essential, g++ and all dependencies .. i have installed!

Or will be there a 32bit-apulse.deb for Ubuntu-users in the future?!?? (LM and Ubuntu are the most choosen Linux-systems ;-) )

If i read the internet of how many people got problems to build apulse and/or to keep it working with e.g. skype i think it's the best time to offer this!

It's confusing enough to find the right config for .asoundrc for individual soundsettings in the net- because there are soooo many different options with dmix, dsnoop, duplex....

Alternative a good and actual online-manual of how to keep apulse (32bit) with skype working on Ubuntu/LM could make it better for many users.

Before i used the official building from sources, i tried this .deb-file of apulse specially for my Ubuntu- trusty-based distro from untrusted ppas: https://launchpad.net/~kirillshkrogalev/+archive/ubuntu/apulse/+packages

but i think it install itselfs in 64bit-modus!?

• So it don't works with apulse skype: Skype has just virtual audio-channels like before!
• with apulse32 skype i just get an error message!

Is there a way to bring this apulse-version to be in 32bit working with skype or another workaround how to fix this building-errors (see above)!???

Thanks for answer!

Video playback is choppy in Firefox when apulse is used. Looks like fps was significantly decreased, with random frame delays.

Reproduced with Firefox 51. When the same Firefox 51 is using ALSA directly, video playback is smooth.

Стим по дефолту слинкован и юзает libpulse.so который так же есть в его бинарном рантайме.
Но при попытке использования нативных либ, и использовании apulse (0.1.4) вместо полноценной пульсы, при открытии настроек в стиме он сегфолтится.

С нормальной же пульсой всё работает нормально.

Skype can't enable microphone if it was disabled by mixer. It would be nice if it will be possible.

Thanks for this project that permit us to get rid of pulseaudio to use Skype.

The only way I get to use apulse with skype is using this .asoundrc:

pcm.duplex {
    type asym
    playback.pcm "dmix"
    capture.pcm "dsnoop"
}
pcm.!default {
    type plug
    slave.pcm "duplex"
}

That works using the Echo/Sound test of skype but that don't work for long in real call:
it works for few minutes and suddenly, no sound is hearing anymore by my voice call mate.

The fact that I use a real audio card with hardware mixing so I don't need dsnoop/dmix combo.
And last point my default output is hw:0,0 but my microphone capture is on hw:0,1.

How can I tell a pulse to use hw0,0 and hw0,1 as respectively my playback/capture device ?

There are functions that Firefox tries to use when capturing audio, which are not implemented in apulse.

To test, open https://webaudiodemos.appspot.com/Vocoder/index.html, select "live input" in "modulator" block and push play button on the page.

Current implementation is not very efficient for audio.
I can recommend implementation made by Jack: https://github.com/jackaudio/jack2/blob/master/common/ringbuffer.c
It's a de-facto standard.
