Amixer controls

Post by tony272 » Thu Apr 26, 2018 2:10 am

Hello, I'm using 2-mic hat.
The driver created lots of mixer controls, I'd like to know how to set them up correctly. Is there any documentation?
For example, ALC controls appear in the playback and capture as well, if I set them for playback, would that change capture as well?
Thanks in advance for any help.

Hey Tony.

Did you check out
It referenced the wikipedia page for ALSA, which then leads here:

Let me know if the documentation here helps.
