The times it even plays, the quality is very choppy and it skips almost like a scratched CD, which makes it pretty much unusable. I suspect this might be specific for my model laptop as I'm having a hard time finding anyone else with the same problem, but I've tried several distros and kernel versions, and the card works in Windows. The laptop is an Elite Group G732, which has a SiS mainboard chipset with the SI7012 onboard controller (Realtek ALC202 chip). I've tried messing with the buffer_size and period_size in asound.conf, which seem to have some impact on the "pattern" of the chopping and skipping, but there are no values that I've found that will get rid of them entirely. I'm assuming this is an incompatibility with the driver and this specific hardware, but I could obviously be wrong. I've tried using the version of ALSA in the 2.6.10, 2.6.12 and 2.6.16.2 kernels, as well as compiled the latest stable and developement releases of ALSA myself. The result is the same for them all. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 04-12-06 04:40 Ensnared New Issue 04-12-06 04:40 Ensnared Distribution => Ubuntu 5.10 "Breezy Badger" 04-12-06 04:40 Ensnared Kernel Version => 2.6.x ====================================================================== ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
