armbian-audio-config fails in minimal images; alsa-utils missing
Description
What happened?
I booted a minimal cli image and found audio output was muted. armbian-audio-config is supposed to set sane volumes for audio devices, but it relies on `amixer` from the `alsa-utils` package, which is not installed in a minimal image.
I originally saw this on a customized 23.02 image on an orangepipc, but I confirmed this by:
building today's main branch
booting it
Installing mpg321
Trying to play some audio file on the minijack output: `mpg321 -a hw:0 sample-15s.mp3`, which produces no audible sound
Installing `alsa-utils`
Using `alsamixer` to see that the "Line out" control of card 0 is indeed muted
Rebooting
Using `alsamixer` to see that the "Line out" control of card 0 is now successfully unmuted and set to 45% (0dB), presumably by `armbian-audio-config`
Using the same `mpg321` command to play audio, which is now audible
The example is maybe a bit contrived, but it serves to confirm the problem.
The main question is, is this situation: 1. Expected (i.e. not-a-bug), because a minimal image is not intended for audio, so if you need audio you should install `alsa-utils` in addition to whatever audio player you also install? 2. Unexpected (i.e. a bug), because `armbian-audio-config` should work in a minimal image too and depends on `alsa-utils`, so that should be installed in minimal packages too?
If 1., feel free to close this issue. If 2., I can prepare a PR to fix this.
Installing alsa-utils on a minimal cli orangepipc image takes up about 6MB of extra disk space (according to apt when installing it).
Medium
