alsamixer doesn't change the real sound volume of my USB sound card (though the dials move okay)

Same issue here. I guess that soundcard is just piece of crap... I've buyed few similar cards from DX (ordered under same SKU at different times). One with yellow led is crap, one with green led is awesome. –  user120577 Feb 28 '12 at 23:33

1 Answer 1

Try running this command

alsamixer -c 1

The above command will control the C-Media card, listed in /proc/asound/cards, which I am assuming is the one you want to control.
