S8 is a not very well supported format.

Those applications already have to deal with the fact some devices only
support 48KHz 16bit stereo audio. I

At that point you can dump the OSS interface just as well.

Tjeerd. I deliberately applied only small bits of your patch before because
the mono mode stuff clutters the driver horribly and is not in the right place.
It belongs in the application/libraries
Then you should kill parts of drivers/usb/audio - it contains format conversions.
