I also am getting the same error. Has any solution for this been found?
Hello,
In Hass.io/Home Assistant OS, alsamixer and amixer are not available in the base system, they are part of a docker container called hassio_audio, you can access from the CLI by running the login command to enter the shell, then run docker exec -it hassio_audio /bin/bash, with that you enter the shell of the container that handles the audio and from there you can run alsamixer or amixer.
Regards
English only please.
sorry, hi all, has anyone come up with a solution/guide? Thanks again
