** Description changed: - My USB speakers worked fine with Maverick and Natty so far. Yesterday, I - tried a suspend to RAM, and my speakers to not play any sound since - then. + UPDATE: + Blacklisting the snd_hda_intel gave me a completely different view in alsamixer. It turned out that the speaker channel was set down to zero volume. + + The bug still remains since channels should not be set to zero + arbitrarily. + + -- + + + My USB speakers worked fine with Maverick and Natty so far. Yesterday, I tried a suspend to RAM, and my speakers to not play any sound since then. So far I have checked all the volume settings in the notification area, the Sounds menu, pavucontrol and alsamixer. I then followed the "Debugging Sound Problems" wiki page and created a sound.conf which looks like this: alias snd-card-0 snd-usb-audio alias snd-card-1 snd-hda-intel options snd-usb-audio index=0 options snd-hda-intel index=1 The USB cards is now in slot 0, but this did not change anything. The card was in slot 1 all the time before and it worked.
