Control the volume of your system
Control the volume of Mycroft with verbal commands or by spinning the physical button on a Mark 1.
Mycroft AI (@MycroftAI)
Configuration
#volume #volume-control #sound #system
i set the volume to maximum level. --> succeeded
volume mute --> succeeded, volume muted
volume unmute --> volume reset to 6
instead of resetting back to 6 every time, it should have return to the previous volume state
using mycroft on cli mode
--> mycroft core version 2002 release 4
--> platform : Linux Mint 19.1
This is my first hand experience with open-source project, please let me know if any other information are required .
Sometimes, when saying "Hey Mycroft" while Mycroft hasn't yet restored the volume will trigger the VolumeSkill again and cause it to believe the last known volume was 0. This causes the VolumeSkill to "restore" the volume to 0 when unmuting, effectively keeping Mycroft muted forever until the user manually restores the volume setting in ALSA/PulseAudio.
For example:
Expected: Mycroft sets its volume back to the previous level
Actual: Mycroft sets its volume back to 0
Pay special attention to the output of VolumeSkill:

This happened to me when upgrading to ubuntu 20, it didnt happen before so i think this package used to be installed by default
adding pyalsaaudio to requirements.txt should fix it

python version does not seem relevant, i can replicate using python 3.8, logs above indicate python 3.6
Cover "Hey Mycroft mute" use case, without requiring "audio", "volume" etc. (Volume.voc) in the phrase. I.e. allow both "HM mute" as well as "HM mute audio" etc.
Remove "silence" from the mute intent and let "HM silence" and "HM silence audio" be handled by the Stop skill. Saying "silence" usually isn't intended to mute, just to stop.
In the same way as with mute intent, allow "HM unmute" without requiring "audio" or "volume" in the phrase.
Make "reset" from the Unmute.voc work not as unmute but to reset the audio level to default (I think it's 6), i.e. as a different intent. (Keep "restore" +Volume.voc as unmute intent.)
Make Mycroft not reply "Audio is going to be muted", just go to muted state without saying anything and...
Indicate the muted state visually, see picture (Mark I face):
Hi,
I copied the latest image of the Picroft for a Raspberry pi 3 B+, but I cannot set the Volume.
It seems there's a problem with the skill since i can manually set the volume from python command line.
https://github.com/MycroftAI/enclosure-picroft/tree/stretch
I get this following error:

Can anybody help me?
Linux and sound is and has always been a pain in the @$$ if you ask me personally. Sound control within the Mycroft software stack is no exception, although A LOT has been improved lately. However at the moment there are some inconsistencies in who is doing what and by using which userland system.
I would like to open a dialog about this, your ideas and figure out the best way forward.
At this moment we can force mycroft-core to use PulseAudio by changing;
"play_wav_cmdline": "aplay -Dhw:0,0 %1"
"play_mp3_cmdline": "mpg123 -a hw:0,0 %1"
to;
"play_wav_cmdline": "aplay %1"
"play_mp3_cmdline": "mpg123 %1"
This all works fine, and WAV and MP3 are played using the default sink of PulseAudio. However the volume control of mycroft itself is handled by this skill (hence the reason I open the dialog here), BUT is forced to use ALSA and its mixers or nothing at all.
Looking at the code of the skill, there are a couple things that jump out;
https://github.com/MycroftAI/skill-volume/blob/19.08/__init__.py#L26
It it using the enclosure - platform config parameter to push it towards using ALSA or not. However if it not pushed into the ALSA_PLATFORM array, there is no fallback other than telling the mycroft.messagebus about it. This should then be picked up by something else. I believe the enclosure code should listen to the messagebus and do the volume stuff as stated here;
https://github.com/MycroftAI/skill-volume/blob/19.08/__init__.py#L132
The strange thing is, there aren't many enclosures at the moment. You have the mark-1 enclosure, but that one is forced to use ALSA here in the skill. There was no picroft enclosure, although a dialog has been started about it and a initial enclosure has been created with two simple controls for shut down and reboot;
https://github.com/MycroftAI/enclosure-picroft/blob/09488ffa30872b032a4e29cb5ef5355ef1d46400/home/pi/enclosure/PicroftEnclosure.py
But again nothing about the volume and again, it is being pushed into using ALSA within the skill.
The mark-2 has its own enclosure code I believe, however volume control of it is being handled by a skill instead of the enclosure code;
https://github.com/MycroftAI/skill-mark-2-pi/blob/master/__init__.py#L185
I don't know why volume for the mark-2 is handled by directly communication with the I2S bus instead of using ALSA or PulseAudio. Probably because volume control via PulseAudio is not supported.
I strongly believe this volume skill should support both ALSA and PulseAudio.
How this could be done in a sane matter is a bit unclear though;
Perhaps a bit of backgrounud information about how I come to this topic.
For MycroftOS I am setting up the system to ONLY use PulseAudio. This to have better control about the sinks and sources using the UDEV modules and let PulseAudio kook up straight into the kernel without the need of the ALSA userland system.
This is preperation for other plugins such as resampling and/or AEC Webrtc of PulseAudio.
For MycroftOS I have set the enclosure config parameter to "MycroftOS" and with that parameter set, this volume skill was not doing anything anymore.
Patched this skill to include my enclosure tag into the ALSA_PLATFORM string
For now I am forcing ALL ALSA requests to pulseaudio using the alsa-plugins, which works just fine.

Hi,
I use mycroft as an assistant on Ubuntu + KDE.
For the last couple of weeks, the volume skill hasn't been working for me.
It responds to me and apparently works fine ( there are no logged errors ), the volume of my computer isn't actually changing.
>> Volume set to 10
set volume to 12
>> I'm not sure I understood you
The expected behaviour if the user sets the volume to an out of bounds integer (ie, 12 in this case) is for the Skill to detect that the number is out of bounds, set the volume to the closest in-bound integer (ie 10) and then notify the user. The actual behaviour observed is that an out of bounds integer causes the Intent to fail.
Wait, why is 10 working? shrug I don't have time to dig into this right now, flagging as #hacktoberfest.
The regex defined at https://github.com/MycroftAI/skill-volume/blob/18.08/regex/en-us/volume.amount.rx
is
(?P<Level>\d+)
this matches integer values 0-9, so 10 and above is out of bounds.
A little bit of regex work would make this intent more flexible.
I had to dig into this repository to figure out how to control the volume except one unit at a time. Here are things I tried before I looked up the right words:
Some other things that might be good to cover:
Consideration needs to be given to how the Volume Skill will interact (or not) with the Common IoT Framework.
Context of the conversation is also an important factor eg
"change screen brightness to 50%"
"turn it up"
This would be interpreted by a human to mean increase the screen brightness above 50%.
As seen in this VK test, "turn it up all the way" can at times trigger other Padatious based intents such as the brightness intent on the Mark 1.
Suggest we look at switching some of these to Padatious.
We have not investigated in detail, but a one-liner patched a problem where a param was getting to a helper function as an int, but should have been a string.
I assume this is happening "up the chain," wherever the skill attempts to address #24, but I'm not sure.
It would be really nice if Mycroft could auto set volume. So if here is much noise the level is high but if it is quiet volume is low.
In my bedroom, when whatching a movie or listen to music there is noise, and mycroft needs to speak loud. But when i am going to bed and maybe my daughter is sleeping in the bed alredy the bedroom is silent. And if i then ask mycroft to turn off light it is anoing if he is replying loudly.
I were thinking that gettig mic level and setting volume acording to that - whith a delay, so it is messured before a spoken command….
Maybe with a high and low setting so he knows what is high and what is low.
