Can kX driver cause problems with a sound format? Discovered this problem on 3544, problem continues on 3545. Problem: I seem to have problems with video files with Vorbis sound (mkv with Vorbis sound). Theres kind of a "zzz"/rapid skipping sound every few seconds. When it gets severe the video slows down also. All other sound types seem ok. At first i thought its the new ffdshow version but when I check back installing the older versions of the codec, the problem still appear. I didn't have this problem before, its not ffdshow so I thought it could be kX. Haven't update my graphics driver for quite a while. Anyway it seems like a sound problem.
