Important addition:
by itself sound can be player with console players (aplay, mpg123)
with Xorg server activity (switching to X11 or screen updated) sound playing breaks immediately

radeon and ATI IXP share same interrupt. Please change component to Video DRI if appropriate. I dont use ATI IXP modem, so i cannot test if it works or not (Its softmodem, no software installed because not needed)
enabling local apic for uniprocessors does not help

enabling SMP too, /proc/interrupts remains the same arrangement PS: (if important) kernel is booting with pci=noacpi acpi=noirq parameters due to problems since 2.6.22 with looping sound and USB dying. I can confirm.
Sound is distorted when I sroll, move windows or change virtual desktop. Before 2.6.34-rc5 everything was good.

Bug appeared in f46c012 commit Does booting with radeon.disp_priority=1 fix the issue? Apply the settings with a cold boot. (In reply to comment #17) > Does booting with radeon.disp_priority=1 fix the issue? Yes, "radeon.disp_priority=1" fix the issue (tested in 2.6.34) (In reply to comment #17) > Does booting with radeon.disp_priority=1 fix the issue? works for me with 2.6.34 release so setting disp_priority to high on all r4xx chips by default isnt that good for RS480 MoBo's with SB4x0 soundcard that have XPress 200m (RC410) Created attachment 26460 [details]
fix
This patch should fix it. I've sent it to Dave to and stable.
2.6.34 with patch and default boot params works too, just as expected ) thanks ) Patch : https://bugzilla.kernel.org/attachment.cgi?id=26460 Handled-By : Alex Deucher <alexdeucher@gmail.com> Fixed by commit 45737447ed160faaba036c0709226bf9057f7b72 . |
Playing sound via ATI IXP SB400 card does not work, qmmp player reports buffer underruns with ALSA, other (sox for example) applications just hangs, its possible to hear sound via FMOD , but its noisy and jerky Last worked: 2.6.33.4 , doesnt work for mainline 2.6.34 (tried with rc6 and rc7-git9) lspci -vv : 00:14.5 Multimedia audio controller: ATI Technologies Inc IXP SB400 AC'97 Audio Controller (rev 02) Subsystem: ASUSTeK Computer Inc.
