Additional Information (if applicable)

  • Software title
    raspberry pi kernel
  • Was the software title installed freshly or updated/migrated?
    yes, migrated to bookworm, worked with bullseye

Steps to reproduce

alsamixer

Expected behaviour

display mixer

Actual behaviour

cannot open mixer: No such file or directory

Extra details

  • the device is recognized and does play, only the mixer seems to be missing
  • same on a pi4 after bookworm
  • alsamixer worked before the migration, in x86 as well

Works after reconfiguring (dietpi-config, sound). Seems that the device switched from 1 to 0.
