Hi,
On plugging in a set of USB speakers I have PA thinks the volume is 100%
but alsa believes otherwise.
Setting the volume in pavucontrol to 100% (i.e. same as what it is just
now - just move the slider a touch) then the alsa volume is instantly
set to the right values.
Please find attached before and after pacmd list-sinks (edited) and
amixer -c1 dumps.
All on git master as of right now (just pushed 12 new patches)
e2df84497629d61706c455ed2829db0bebb7e5a5.
