with 2.4.2x alsa drivers worked so good.
now when i play sound, with every player, mplayer, xmms, kde stuff and so on..
i got a bad sound, with flicks, rumors and so on.
i see that the noises are even worse when my secondary hard disk is used (ex. when playing a divs
from that hd). disabling dma on that hark disk seems to reduce pretty to 0 the problem.
i repeat i has this problem since i used 2.6.x kernel while 2.4.x worked good with a clean sound.
Not a hardware problem cause in Windows or old kernel it still work good.
as you can seem system reconizes my sound card as 1370. i tried 1371 module but it didn't work at
so actually no solution.
probably due to IDE busmastering and however a really buggy ide driver
still bugged on 2.6.9-rc2
still there in 2.6.9 and .10-rc3 too.
even it a bit better.....
i confirm same bug for 2.6.10 and 2.6.11-rc1.
tried 2.6.11-rc3 and 2.6.11-rc3-bk9
seems again a little better, but not perfect as 2.4 or windows
come on fix that please!!!
rc4 bugged too.
2.6.14-rc* still bugged!
do something please!
It's not related to sound (except that the soundcard makes the problem visible),
but likely to ACPI or PCI bridge or IDE controller setup.
stand bugged on 2.6.14 stable release
seems now i got it **pretty** fixed.
what i did:
1) updated kernel to 2.6.14-git4
2) setted 100Hz instead of 250
3) setted latency to 0x40 (64) instead of old 0x20 (32)
4) disabled pci 2.1 in my bios.
