ASUS Xonar U3 volume slider problem
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.
