Title:
[USB-Audio - USB Device 0x47f:0xad01, playback] volume slider problem
Status in “alsa-driver” package in Ubuntu:
New
Bug description:
Sound from my headphones disappears when the volume slider is around
30% along.
A look at alsamixer in the terminal shows the PCM value is 0<>0 on the audio
device.
The slider in Ubuntu's desktop environment is at 100% when alsamixer shows
PCM is at 100<>100 or Item: PCM dB gain: -0.06, -0.06
The slider is at 30% or so volume when I cease hearing anything and the PCM
is at 0<>0 or Item: PCM dB gain: -28.19, -28.19.
