It's important to know whether it's a problem of usb-audio or the OSS
emulation.

First, you can try aoss wrapper for the user-space OSS emulation.

Also, try "buggy-ptr" option for oss proc file (see
ALSA-Configuration.txt).  This is a newly added option for the apps
which assume the broken implementation.
