Comment 8 for bug 93600

I can confirm the bug on my Gutsy, 2.6.22-14-generic #1 SMP, with HP Pavillion dv5000 / Intel sound (same as darth_schmoo):
I get no effects if I change (up/down/mute) the master channel volume (with KDE KMix, or command-line alsamixer, or with the volume keys on the keyboard). instead, PCM channel does work fine (except at loud volume levels: as on Feisty, the sound becomes lightly distorted, while with winxp I hear it clean - but this is another question).
