Using other DAC's outputs on Raspberry Pi about norns-image HOT 4 CLOSED

we don't actually do any ALSA control within matron. the headphone gain is controlled via i2c (trace the commands to find the inner workings, but it doesn't seem to apply to your case).

if you want to issue ALSA commands, just use os.execute from within lua and that should work fine.

but generally other DACs and sound cards should work fine out of the box provided you set up jack correctly, so i'm going to close this. feel free to continue to comment and i'll attempt to answer questions.

Thanks - further digging led me to the same conclusion regarding ALSA

FWIW - the WM8731 DAC works great for audio output and input - output levels are controlled OK with the volume controls. However, the input volume levels can't be controlled from the norns software as it looks like that's happening in i2c.c .

I'll keep digging.

the input gains are obsolete-- the hardware was removed. so that i2c code will also go away.

Understood. Thanks!
