Volume on OSS SB Live!
The problem described here is present on all versions of OSS SB Live! driver, but I think it does not appear on all card versions. The problem is as follows: If the PCM volume is set in 80-100% range, an audible sound distortion appears. It's especially noticeable on decent speakers (or headphones) when sound dynamic range is big.
Here's my simple kernel patch - I've been using it
on all 2.6.x kernels released so far.
It should work without problems on the drivers in 2.4.x tree and original out-of-tree Creative drivers.
