From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.7 (X11; Linux i686; U;) Gecko/20030131 Description of problem: Audio sounds choppy and full of static, sort of like a bad FM channel. The onboard soundcard appears to be sharing an IRQ with USB, but the BIOS does not support assigning specific IRQs, and /usr/src/linux-2.4/Documentation/sound/ contains no documentation related to modifying the driver's settings. Here is the relevant output from various utilities. From procinfo: irq 9: 94314 usb-ohci, SiS 7012 From dmesg: Intel 810 + AC97 Audio, version 0.24, 07:13:38 May 29 2003 i810: SiS 7012 found at IO 0xd400 and 0xd000, MEM 0x0000 and 0x0000, IRQ 9 i810_audio: Audio Controller supports 6 channels. i810_audio: Defaulting to base 2 channel mode. i810_audio: Resetting connection 0 ac97_codec: AC97 Audio codec, id: ALG32 (ALC650) i810_audio: AC'97 codec 0 supports AMAP, total channels = 6 From lsmod: Module Size Used by Tainted: PF i810_audio 27624 0 ac97_codec 14600 0 [i810_audio] soundcore 6404 2 [i810_audio] From lspci: 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 PCI Audio Accelerator (rev a0) Version-Release number of selected component (if applicable): kernel-2.4.20-18.9 How reproducible: Always Steps to Reproduce: Play any MPG or AVI file using xine, gmplayer, mplayer, or similar. Actual Results: Poor quality sound. Expected Results: Normal sound output. Additional info: Files play fine on different machine with a different onboard soundcard and running RH 8.0.
