Audio matrix settings.

[SonnyWalkman]

What is the format for for setting up audio for inputs such as kind=test audio matrix? The current core instructions mentions nothing on how to configure audio parameters. I'm struggling using ini files in the configs directory to work out how audio is configured.
Is there any examples would help me out please. I require a simple stereo for all sources to connect to.

Hope I was solving same problem as you.

Here is code for parsing audio_map to gst audiomixmatrix

voctomix/vocto/audio_codecs.py

Line 38 in 27e2c58

for mapping in mappings:

Here is documentation for audiomixmatrix https://gstreamer.freedesktop.org/documentation/audiomixmatrix/index.html?gi-language=python

So in config.ini:
audio_map=from_channel,to_channel;from_channel2,to_channel2

For example:

audio_channels=2
audio_map=0,0;1,1
