Open Sound System

It seems your using a package manager for installing oss. Usally the packages only contain the binary. To make the changes mentioned earlier you need to build and install oss from source. This however might not be easy if your not experienced with building from source.

I've tried some more to get it working by using different play-alt values but the result remains the same. I also tried to enable the trace and mixer options in the usb configuration file without success. It seems that alsa should support this chip so I browsed their code for a while but I can't fin...

I've built a usb soundcard around the pcm2902 ti burr-brown ic. It works like a charm in windows but I can't get it to work with oss.
