I have an on-board C-Media sound chip and a Creative PCI sound card. When I use either of those cards to play a file with a program that uses the Alsa output, it keeps repeating the first second. When I play a file with OSS output, it jumps quickly through the file. But sometimes it works flawless. I have no clue what causes the driver to work or not. I tried rebooting vs cold boot etc. but I can't figure out what causes the driver to work. When I enable debugging in the kernel, it throws the following error: Time: 01:02.04 [00:00.00] of 00:00.00 ( 0.0%) Output Buffer: 2.75MALSA sound/core/pcm_lib.c:157: BUG: stream = 0, pos = 0xf7de, buffer size = 0x4000, period size = 0x800 Running alsaconf doesn't make any difference. When I enable the on-board sound chip and have the PCI card inserted, the audio works fine, but it doesn't always use the same device. I can choose the correct device with alssaconf, but when I reboot, it sometimes uses the other device. I noticed that both cards have the same IRQ. I would like to use the on-board sound, and remove the PCI card.
