AFAIK , only those STAC920x codec has SND_CTL_TLV_DB_GAIN_MUTE
Also some broken HDA cards,
Where "some" = "those that use a STAC920x codec".
Ah, ok :D
What is not any driver bug?
That the hardware reported a wrong dB value for the lowest volume setting. The latest driver has a workaround.
Is it a bug in alsa (the driver or alsa-lib or whatever) if snd_mixer_selem_get_playback_dB_range() returns something else than SND_CTL_TLV_DB_GAIN_MUTE as the min gain, if the lowest volume step for the element is mute?
Yes.
Thank you for the answer!
