Hi All, I've been having some weird problem with my new mainboard which has an onboard VIA ac97 sound card When I set everything for OSS drivers, xmms plays mp3 files like a stuck record player. I can move around the music file but it gets stuck in the first second. When I try the piece of code I have written to use OSS techniques, my simple program which is supposed to play an instrument file with half a second of music recorded, the card plays the sound repeating it indefinitely (until I abort the program). The I switched to Alsa. When I use Alsa xmms plays fine but my piece of code (unchanged, still using OSS calls) repeats the sample 32 times in 2 channels (stereo), 16 times in single channel (mono) Linux is MDK 9.2. I tried the same things on a Dell notebook with exactly the same Mandrake 9.2 (installed from the same network NFS server) but ofcourse a different sound card, everything works fine. Therefore it is certain that the problem is with the sound card driver.
