audio volume very low (almost unhearable) on samsung,a5u-eur on all outputs (speaker, headpiece and headphone)
Describe your issue
What's the expected behaviour?
Audio should be hearable on speaker, earpiece and headphone with a decent volume. It was hearable just fine on v21.12, and very loud, actually.
What's the current behaviour?
Audio is almost unhearable (on 100% volume in both alsa and PW mixers). It almost seems as an internal amplifier is not enabled by default and one hears the raw output of the DAC. I'm at a total loss of which switch that may be (there are hundreds of switches in the alsa mixer).
How to reproduce your issue?
pure alsa test
speaker-test
PW test
mpv $AUDIOFILE
What device are you using?
samsung,a5u-eur
