Bug Description
I am using the kernel backport from Maverick to Lucid. The summary of this problem is that at seemingly random times the sound skips almost like it does not have sufficient hardware to play it, which also results in totem and flash video skipping. It corrects itself, however does happen again at random times. I took debug information for this report after such an occurrence.
Symptoms:
1.) The sound card pops and crackles during log in, and the log-in noise is delayed.
2.) After login the sound functions normally and seems to have good latency.
3.) At random times the sound skips, and takes video playback with it, however it does sort itself out.
Steps to recreate:
None, I am assuming anyone with this sound card would have this issue. My hardware is a stock Asus k50ij laptop.
Notes:
Fedora 13 has a lot of problems with volume and playback with this chipset, it seems Ubuntu does not. I also plan to do upstream testing on a mainline kernel, though I have not done so yet.
