I asked this question on freebsd-stable, but they tell me to ask this here. Here is the original mail. Recently, I updated my kernel & world. And I found that this problem becomes worse -- my /var/log/message was filled up with something like Dec 14 08:13:16 compaq kernel: pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead It's really a problem now. ---------- Forwarded message ---------- From: Zhihao Yuan <lichray@gmail.com> Date: Wed, Dec 1, 2010 at 3:53 PM Subject: pcm says `channel dead' with snd_hda To: freebsd-stable@freebsd.org ~> uname -a FreeBSD compaq.yuetime 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #8: Thu Nov 25 15:48:19 CST 2010 root@compaq.yuetime:/usr/obj/usr/src/sys/HOUKAGO amd64 Sometimes, pcm prints the following message to the console & dmesg. pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead What's wrong? I haven't seen this in 8.1-RELEASE or other version before. One post said that such message comes with noise, but I'm not sure. I uses mplayer, sometimes quodlibet (gstreamer backend). -- Zhihao Yuan The best way to predict the future is to invent it. -- Zhihao Yuan The best way to predict the future is to invent it.
