Bug Description
I am on a Geode LX system with CS5536 audio chipset. Using 2.6.32 in Lucid, OSS4 worked great. With 2.6.35 in Maverick, the modules load, no errors are produced besides a warning that my feeble hardware is incapable of mixing multiple audio streams, but no OSS4 audio. I had the same error/warning in 2.6.32, but had working audio.
I just grabbed the latest mercurial sources from OpenSound.com, built the source, and have working Opensound again. I'll report the bug as an OSS4 deb package bug.
As per the forums, other people on other architectures are merrily using OSS4 on Maverick. I have thus deduced the issue to be CS5536 specific, in the 2.6.36 kernel. I don't know if it is Ubuntu-patch related or 2.6.35 mainline related.
