Public bug reported:
I got an ASUS Xonar U3 USB sound card for my Thinkpad T420 for my
birthday this year and tried to use it on Ubuntu 12.10. Unfortunately,
its sound output is either bearably noticeable or - if I increase the
volume by even the slightest notch with the audio indicator - EXTREMELY
loud (and, because I use earphones, pretty painfully so).
I did some experiments with alsamixer, and it seems as if the complete
volume range that I would expect to be stretched over the complete
slider is compressed in the PCM levels between 1 and ~7. This means the
only way I can sanefully use the USB sound card right now is by turning
the volume in each application very, very low so that I have some amount
of precision with the global volume slider (which I can control with
function keys), but every time I forget this somewhere, it's a pretty
painful surprise, so I hope this can be fixed.
