I don't know too much about OSS utils / devices, but I would start by enabling the rec devices and seeing what changes every time.... increase the volume of everything all the way up (careful with your ears though!).

for reference, mine shows:

$ mixer
Mixer vol      is currently set to  86:86
Mixer pcm      is currently set to  85:85
Mixer speaker  is currently set to  49:49
Mixer mic      is currently set to   0:0
Mixer cd       is currently set to  40:40
Mixer rec      is currently set to 100:100
Recording source: mic

Did you check OSS docs  for samples? you DO have a mic connected to one of your inputs...and the mic is NOT muted right? (trust me, it happens to me every second day..) 

sorry I can't be of more help atm.

cheers,
beto
