Linux system freeze

Hi, on Linux Mint 19.3 / Ubuntu 18.04 (tested with kernel 4.15 and 5.0), the first time I plugin the Tascam US 122, the USB led does not power on, so I disconnect and reconnect it, and after few seconds it lights on, but about 30/45 seconds later the system completely freezes. In that situation I must power off the PC, not event the AltSysRq reboot works, and there are not traces in the journal logs.

Could somebody help me?

Thank you so much!

"state" param in status file constantly set to RUNNING

I'm trying to detect when sound is being produced or not based on the state parameter in the status file, however without any sound being produced, the parameter is set constantly to RUNNING.

This is on a raspberry pi, no virtualisation. The status file has an owner_pid set however there are no running processes on the machine with that pid.

Website presents incorrect TLS cert

Hi @markc - Looks like there's an issue with the TLS cert. When I visit http://alsa.opensrc.org/ I'm redirected to https://alsa.opensrc.org/ (which is great! TLS everywhere is 👍). However, the certificate that's presented is for opensrc.org, and not alsa.opensrc.org, and is not a wildcard cert (I see it's from Let's Encrypt, which doesn't yet do wildcard certs).

I was thankful to discover that all the docs are in markdown format in GitHub, so it's easy to just browse them here. But it would be handy to get the cert properly issued 😉

No control over IEC958 output

I am sorry but i have a special problem with an old but good sound card (Terratec sixpack).
$ cat /proc/asound/cards
0 [CS46xx ]: CS46xx - Sound Fusion CS46xx
Sound Fusion CS46xx at 0xfeafe000/0xfe900000, irq 18

I am using this card as optical soundcard in an multimedia system.
It worked good for years but now i must set up a new mainboard.
I could migrate the installation to the new hardware without problems except the sound.
The sound is working only as analog output - the IEC958 optical output will not work.

I tried everything with alsamixer and the PulseAudio pavucontrol.
I can mix and do everything with the analog parts but the optical output keeps dead without error.
I also tried to access it with aplay -d hw:0,0 in every port combination.

The interesting thing is that on the old system (i could reactivate) the optical output is always on - it could not be switched off neither with alsamixer or pavucontrol !?

So at least there is no control over the IEC958 output!

I already checked everything in this description:
http://alsa.opensrc.org/DigitalOut
There are others with similar problems out there e.g.
https://forums.gentoo.org/viewtopic-t-784352-start-0.html

Maybe there is an dependency that there is an additional HDMI sound device on the new system?
But how can i check anything regarding IEC958?

Thanks for any kind of help.

Set default format S16_LE asound.conf

Hi everyone,
i need to set as default format S16_LE without specify it into "arecord" command.
I would to record cleanly as much i can my voice from microphone

Can anyone help me?

VU Meter peak detection -- wrong masking operators?

I'm trying to fathom the masking operators in aplay.c (which is also arecord). I'm looking in:
static void compute_max_peak(u_char *data, size_t count)
which is near line 1650. I see these commands, (in this case for 8 bit samples):
signed char mask = snd_pcm_format_silence(hwparams.format);
c = 0;
while (count-- > 0) {
val = valp++ ^ mask; / <=== IS THIS RIGHT? */
val = abs(val);
if (max_peak[c] < val)
max_peak[c] = val;
if (vumeter == VUMETER_STEREO)
c = !c;
}

That masking command, which often masks with 0x0 but occasionally with other values, esp. for bigger sample sizes, seems like it ought be: val = *valp++ & (~mask);

Of course, perhaps i really misunderstand what's going on in the 'silence' function, which seems on rare occasions to return 0x8000 and the like, where the '8' is in the sign bit.

What does the exclusive or do???

Default Configuration For Outputting to Both or ALL sound cards

I know there is some enigmatic way, to make ALSA drivers through virtual output to output to both cards at once.

using something like:
pcm.both {
type route;
slave.pcm {
type multi;
slaves.a.pcm "sblive";
slaves.b.pcm "onboard";
slaves.a.channels 2;
slaves.b.channels 4;
bindings.0.slave a;
bindings.0.channel 0;
bindings

I myself did not succeed in it.
However even author of this solution said it is too complicated.
Could you make it part of default configuration option?

If there are multiple sound cards detected:
then it could be some easy option or script commands to add this abstraction layer:
on Main board and HDMi on board of graphic cards.

I know laptop and other mobile devices default setting need to be different, It is important on them to save power and energy consumption, but for desktop I suppose it is important to save time, and make playback available on all devices at once.

I know it may be same advanced cases, to make playback on multiple sound cards totally independent of each other.

But I suppose it can be done simple by adding to mixers some additional Tabs:
1st card playback
2nd card playback
3rd card playback
Both card playback
ALL card playback
Such should be Default Config.

From user experience it should be so simple as changing time zone.

Focusrite usb 2 hour limit

https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/3790

same happened in Windows,
i also contacted Focusrite support back then.

play a >2 hour long video or music file with VLC snap,
will crash near 2 hour of continiuous play.

does Not happen with ASIO drivers in Windows,
also does Not seem to happen with JACK Qjacktl,
Only PulseAudio, same as WDM did.

VLC 3.0.16 aptitude does Not work with PulseAudio set to 48Khz,

$ cat /etc/pulse/daemon.conf

VLC 3.0.16 only works at 44.1kHz.
VLC 3.0.19 Snap works ok at 48Khz, or 96Khz, but... Jack does Not, does Not detect vlc-plugin-jack
i have a disagrement with a french VLC developer about that.
does Not want to fix VLC Snap, and VLC aptitude 3.0.18-4 does Not want to support 22.04 LTS release.
only supports Mantic

Focusrite usb also had another problem with ASIO drivers in Win,
buffer was Not syncronized when monitoring input for long periods of time, had a gap, reset, hiccup.
different buffer size, different time for the buffer hiccup to repeat.
i have Not detected that with Jack.

Where does the "alsa" command come from?

I'm trying to follow this document.

I'm on Debian Bullseye amd64 and I have no alsa command, be it installed or available for install with any package. I do have alsactl but it takes different options and I don't know how to map the instructions to it, assuming it were the right thing to do in my case.

Is it my fault or is the document outdated?

Update alsa on DEBIAN

Hi! How to update alsa-drivers on Debian?
Thank you!

Hello...BeagleBone Black and Daffodil USB Sound Adapter/Seth

Hello Again,

This is Seth. I am trying to make a bot. I know you could care less but I am using alsamixer to promote sound. I tried to play a .wav file with a Daffodil USB Sound Adapter. I could only get voice input. I could not get any voice/music output.

The speaker works and the Daffodil USB Sound Adapter says on and I get feedback but no music.

I was wondering if anyone else brought up this complication. Is alsamixer having trouble with some USB configurable devices? I do not want to blame the alsamixer or the BBB but I configured with F6 via Ethernet and PuTTY on my BBB.

If you could send some support, it would be very helpful. I am working out of the book, "BeagleBone Robotic Projects." The information, if you have the book, is on page 71 through page 73.

Sincerely,

Seth

Ubuntu 14.04 : Udev rule to change the alsa number for similar USB sound cards.

Hi,

I tried the udev rule described here: http://alsa.opensrc.org/Udev

Since PHYSDEVPATH is deprecated, I changed the perl to act like the C++ code. (I'm passing the %b to retrieve the usb port number).

When I receive
pcmC1D0p
I return instead:
pcmC25D0p

but a cat /proc/asound/cards does not show card 25. Still card 1.

Any help really appreciated ! Very urgent, thanks.

Focusrite Clarett 8pre USB vs. Scarlett 18i20mk3

ID are different, serials,
But in theory Scarlett mk3 should work to control Clarett USB
digital control hardware is technically the same...
hardware features the same...
win/mac control software the same...

the only change is analog circuit, audio capacitors, op-amps, external case,
maybe power supply..

Clarett+ 8pre USB similar change...
Not digital control, only Analog circuit, latest DACs, exterior case.

Adobe flash firefox audio issue.

issue may have been present before the flashplugin 27.0.0.130-1 update but I just noticed it today after updating yesterday.
issue: a flash stream is playing audio in firefox. while streaming, open another audio source (such as vlc or audacious) which doesn't play audio and this is logged:
pulseaudio[x]: E: [alsa-sink-USB Audio] alsa-sink.c: Error opening PCM device front:2: Device or resource busy
the reverse is true: vlc or audacious is playing and when attempting to play a flash stream in firefox, the video is fine but there is no audio on the stream. either nothing is logged or this is logged:

pulseaudio[x]: E: [alsa-sink-USB Audio] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write.
pulseaudio[x]: E: [alsa-sink-USB Audio] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers.
pulseaudio[x]: E: [alsa-sink-USB Audio] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

issue is not reproduced in chrome (assuming this is an NPAPI (or firefox) issue since I also have pepper-flash installed.)
issue is resolved once the stream is stopped or the browser tab is closed.

my device: FiiO e10k (inxi: GYROCOM C&C) usb headphone amp. xfce audio configuration recognizes it as "DigiHug USB Audio", set as "analog stereo output".

xone23c mixer

Having a few problems with the Xone32c though not sure if this is an ALSA
issue or general USB stack problem.

It's a USB soundcard that is supposed to have 4 inputs and 4 outputs. It
seems to have 2 USB configurations (bNumConfigurations : 0x2). When plugged
in, bConfigurationValue is 0x1 and only 2 inputs and 2 outputs show up.
Change this value to 0x2 and it shows up (as it should) as 4 inputs and 4
outputs.

I can change the bConfigurationValue with this udev rule, or with a `echo 2

/sys/bus/usb/devices/1-1.4/bConfigurationValue`:

This has all been working OK on Ubuntu 20.04 running kernel
5.4.0-33-generic. However, I just updated to 5.4.0-37-generic and now there
is only a single USB configuration (bNumConfigurations : 0x1) and
bConfigurationValue can't be changed to 0x2:

C-Media USB Audio Device (0d8c:000c) volume scale

I'm not sure if this belongs here, but the ALSA bug tracker (http://bugtrack.alsa-project.org/alsa-bug/) is down...

I have a DeLock USB audio device with an C-Media audio chip. When changing the volume in alsamixer there is no problem, but when changing the volume through any PulseAudio frontend (in my case pavucontrol and veromix-plasmoid), all volumes below 30% in the GUI are shown as 0% in alsamixer and no sound is played.
The PulseAudio wiki blames this on ALSA for exporting incorrect dB information. However this StackExchange answer suggested adding the parameter ignore_dB=1 in /etc/pulse/default.pa which fixed the issue, so I'm not sure if this is indeed ALSAs fault?

I've "attached" some debugging information, however I cann't seem to find the aadebug script mentioned in the wiki:

403 at https://alsa.opensrc.org/.asoundrc

Guess you have a line that over-eargerly catches access to dotfiles in your nginx config ;)

no sound on my old ice1712 based sound card.

Hello, since a few days, i have no sound on my old hoontech dsp 24 sound card. I'm on Ubuntu mate 22.04 but the problem occurs also with several debian live cd's.

I don'tt have the "digital mixer to ac97" in alsamixer any more.

Dmesg | grep snd shows this :

amidi should ignore 0xF8, not only 0xFE (active sensing), when receiving SysEx dumps

amidi (unless -a is used) ignores 0xFE (Active Sensing) messages, This is good. But for the same reason it should also ignore 0xF8 (Timing Clock). Because it doesn't I can't properly fetch a SysEx dump from my Yamaha Reface DX, or from a Yamaha V50 or YS200 for example. These synths not only send streams of 0xFE but also 0xF8 continuously. amidi doesn't correctly detect the end of a sysex dump from my synth, because it still detects 0xF8 bytes coming out of the synth.

Instead of filtering only 0xFE, all bytes from 0xF8 to 0xFF should be filtered out. Or at least 0xFE and 0xF8.

custom palettes on AlsaMixer

hi! i’ve been using AlsaMixer since years! i’m now using version 1.0.29 (from Ubuntu 15.10 repository)

it needs a possibility of changing the colour palette - sometimes we need, for example, dark text over bright background, and so on - and would be even great if we could create and share palette files at opendesktop.org and alike

a bug or misfeature i found is that, on Unity volume control (Ubuntu) we are able to have amplified volume, but when we adjust the volume back on AlsaMixer, the amplification automatically switches off, and we find no way to have amplification back from there

thanks and cheers,
p.

RE: Hello Again Sir/Ma'am

Hello,

I have this new error code and I am trying to figure out what the code stands to admit. Here it is: aplay: playback:2715: read error.

Sincerely,

Seth

P.S. If you have time, please reply. I have been typing in this error code while looking online for ways to get around this code when trying to play .wav files from my PuTTY prompt with a BBB (beaglebone Black).

device list classification misc?

in the file https://github.com/markc/alsa/blob/master/lib/md/Aconnect.md#example-sblive-soundcard

it said that 0..63: for internal use (0 = system, 63 = OSS sequencer emulation)
64..127: device drivers (up to 8 for each card), i connect my keyboard midi piano and seems does not fit with such example list

snd_hda_intel bug

I've been having this issue for a week now and I have been trying to figure out why my audio just dies when I am doing stuff. It mostly happens when I am gaming but has happened to me while just browsing. The audio just dies and I have to refresh the pages or reopen some programs like teamspeak. The only thing that I have found recently is this


 Oct 26 19:04:50 ali-pc pulseaudio[12382]: E: [alsa-sink-ALC892 Analog] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write.
Oct 26 19:04:50 ali-pc pulseaudio[12382]: E: [alsa-sink-ALC892 Analog] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

Oct 26 19:04:50 ali-pc pulseaudio[12382]: E: [alsa-sink-ALC892 Analog] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

I am not sure where I can find logs to futher help you out. Please notify me with what I can do to debug this.

Thank you,

User Configuration Dunno - Capture from 3 sources?

Hi there, i am Slackware(64) 14.2 [i had both version 32 & 64 Bits in different partitions]. i had the follow dunno :

Its possible configure alsa to enable record from 3 different sources each with volume control ? because i am trying to configure alsa to capture from single sound card : Mix, Mic & Line

Please, another users read this, i don't want nothing of pulseaudio, i really don't like it.

I ever see i can record from one source and i just can choose one from various options available

Well Suppose the follow, i want

1) Play a background music (mix)

2) Record my voice from the mic connected in the Mic Jack Port of SoundCard

3) Record the notes i press, from my midi keyboard connected in the Line Jack Port of Sound Card.

i want to know if really is possible to configure alsa to make something like (this is mockup make it by myself on gimp)

Because i had days searching information but ever are examples or configuration for use with two or more sound cards.

like this :
http://www.jrigg.co.uk/linuxaudio/ice1712multi.html

or this another one :
https://stackoverflow.com/questions/8043912/is-it-possible-to-capture-both-mic-and-line-in-at-the-same-time-using-alsa

I had publish this originally on this Slackware Forum -> https://www.linuxquestions.org/questions/showthread.php?p=6116801#post6116801

i think this can be done writing correctly the file ~/.asoundrc but i no had idea which things i need, because i try to run

man alsa

Output :
Don't exist any page about alsa

And well without examples or which things i can configure inside that file i need help for that.

Slow/piecewise send of sysex?

I'm using amidi --send-hex to send data to a Commodore 64 via a CLab MIDI interface. The problem is that even with 100 bytes the probability of a buffer overrun is about 30%. I didn't find a way to throttle the send speed. I also tried sending the data in smaller chunks, but I cannot get amidi to send anything after the first chunk. I suspect it refuses to send anything if the data doesn't start with F0 i.e. sysex dump start.

If I am right about that assumption, as a workaround I could encapsulate each chunk as a full sysex dump, but that requires extra logic on the receiving side and it also wastes bandwidth, so I don't really wish to do that.

Primarily I would prefer a way to throttle the speed, but if I cannot have that, I would like to be able to send the data a few bytes at a time in a simple shell loop.

what is the config file to set 6 channels

I have Ubuntu Mate and after every minor update pushed by Mate I lose my 6 channels. I have to start alsamixer and set to 6 and it works, but there should be a way to set it permanently.
Please, help.
