My patch is there and compilation should be fixed. ---------------------------------------------------------------------- parente - 05-31-05 14:04 ---------------------------------------------------------------------- perex: I can now compile and insert the module into the kernel on my machine. However, the clipping problem still remains. Considering that Roger Mach's patch works, I do not believe this is an overflow problem. Rather, the bug seems to stem from an incorrect calculation involving bytes instead of the desired frames.
