Can you try re-compiling the kernel with SOUND_OSS_CORE (I don't
remember which option activates this flag)? Though I did not face this
issue in my current kernel config (2.6.36.1), but I remember that one
of my old box had a similar issue. It got resolved after I had enabled
some parameters for OSS (ironically, which seems to be deprecated in
current kernel !)

May be this can help.
