Hello All,
A couple of years back I've asked on this list how to add a dummy volume
control to an audio device. As suggested back then I modified
asound.state file and added the lines below the mail. This works great
in most situations, except for one. I would like to also have it return
dB values, however, it doesn't (function
snd_mixer_selem_get_playback_dB_range fails).
I've tried several things (below is one of the versions), like copying
the values from the mixers that come with the snd_dummy driver, but
nothing seems to work. Obviously that's just guesswork but I'm unable to
find the right documentation on this.
Is this even possible? If so, how, or where can I start my quest for an
answer?
Kind regards, Maarten
