Start alsamixer (or aother "good" mixer app), scroll right with the cursor key, choose "External" (shown "External Amplifier" in the item line) then push 'M' to toggle on/off.

I don't know how this happend. The driver default is 100%. To fix this, again, start alsamixer, choose 'DAC', and raise with the up/down key. > > /proc/asound/card0/codec97#0/* files would be helpful for debugging. > > I don't seem to have such a thing. I tarred up /proc/asound. Also attached. Hmm, it's ridiculous. You don't have /proc/asound/card0 directory? (It should have nothing to do with the "silent" problem, though.)
