DietPi-Config | Audio: Add MATRIX Voice support

[LexiconCode]

Mycroft AI set up use to include setting up the audio device. I have a Voice Matrix add on board that used to be set up through Mycroft scripts. What would be your suggestion to proceed trying to set up Voice Matrix board with DietPi?

The script as a reference.

@LexiconCode
Which Mycroft script in particular sets up the sudo device? Didn't know that. Ah you linked it :)

About the Voice Matrix I found this install instructions: https://matrix-io.github.io/matrix-documentation/matrix-core/getting-started/core-installation/ https://matrix-io.github.io/matrix-documentation/matrix-voice/troubleshooting/ (replace $(lsb_release -sc) with $G_DISTRO_NAME)
As a promoted setup it should work with RPi. I can add this to DietPi-Config as well, as I anyway plan to rewrite the audio options with next version.

Setup steps of Picroft: https://github.com/MycroftAI/enclosure-picroft/blob/8c2de9ad0d7bfed8f5c08f7a505a71bdf4584034/home/pi/auto_run.sh#L777

I'll take a look and also review the rewrite the audio options with next version.

The following should work:

curl -sL https://apt.matrix.one/doc/apt-key.gpg | apt-key add -
echo "deb https://apt.matrix.one/raspbian $G_DISTRO_NAME main" > /etc/apt/sources.list.d/matrixlabs.list
G_AGUP
G_AGUG # Assures current kernel is installed
G_AGI matrixio-kernel-modules
reboot

Now aplay -l should list an entry for the MATRIX Voice, I guess it's card 1.
In /etc/asound.conf replacing card 0 with card 1 and in case 0,0 with 1,0 might work. But honestly I don't know about all the magic that you can do with this the MATRIX Voice, might might require to use different sound card or device 😉.
aplay -l at least should give a hint and when the related card has been added to asound.conf, alsamixer to tune levels and/or toggle some switches.

@LexiconCode
Wow, that package pulls a lot of dependencies, although python-setuptools seems to be missing, good to know. Could you paste:

apt show matrixio-kernel-modules

Tried using https://github.com/matrix-io/matrixio-kernel-modules/blob/master/misc/asound.conf

Ah nice they provide one, even two configs. For the microphone card "MATRIXIOSOUND" is used. Could you check this is available? arecord -l

Also you might play with alsamixer, if anything does not work.

I don't like that the card is called Dummy so far, but perhaps that is expected. You did a reboot afterwards, just in case any additional module/overlay needs to be loaded on boot?

[LexiconCode]

I did Reboot afterwards.

Depends: matrixio-creator-init

Ah okay the tools are pulled as well: apt depends matrixio-creator-init

Does it work for playback and recording then?

Sure I'm looking for the commands to do the record/playback. Once I figure that out I'll let you know.

aplay and arecord for .wav files.
mpg123 for .mp3 files (apt install mpg123)
