My sound hardware consists of the following: hdac0: <NVidia MCP78 High Definition Audio Controller> mem 0xc0000000-0xc0003fff irq 19 at device 7.0 on pci0 hdac0: HDA Driver Revision: 20100226_0142 hdac0: [ITHREAD] hdac0: HDA Codec #0: Conexant CX20561 (Hermosa) hdac0: HDA Codec #3: NVidia MCP78 HDMI Whenever I try to play some sound and my machine is doing something else at the same time (like changing the wallpaper in KDE4 automatically while playing a song in Amarok) the sound hangs and dmesg reports the following: pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead How-To-Repeat: Just boot the machine and the startup sound is already distorted (that is - one small sample is played repeatedly during the duration of the sound).
Alexander, perhaps you have a suggestion here? Maybe this is related to msi, nVidia chipset seemed to frequently have problems in that department. -- Andriy Gapon

I see this buggy behavior but with a very different sound device, on 9.0-RELEASE. Sound play for 3 seconds and stop with: pcm0: chn_write(): pcm0:play:dsp0.p1: play interrupt timeout, channel dead The device is SiS 7018, using snd_t4dwave driver. I also tried to turn off ACPI without luck. Perhaps my problem is related? For your information this problem is reported on ES1370 too: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/129604 mpg123 fails. Tried "dd if=/dev/random of=/dev/dsp" too, getting same behavior. Do you think it helpful if I post more info like dmesg and various hardware data? mpg123 output follows. $ mpg123 Downloads/In\ The\ Shadow\ Of\ The\ Valley.mp3 High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3 version 1.13.4; written and copyright by Michael Hipp and others free software (LGPL/GPL) without any warranty but with best wishes Directory: Downloads/ Playing MPEG stream 1 of 1: In The Shadow Of The Valley.mp3 ...
