In 9.1 there is an issue with the snd_hda driver. My sound card is an onboard chip: hdac0: <NVIDIA MCP61 HDA Controller> mem 0xfce78000-0xfce7bfff irq 23 at device 5.0 on pci0 hdac1: <NVIDIA GT108 HDA Controller> mem 0xfcf7c000-0xfcf7ffff irq 17 at device 0.1 on pci2 Sometimes (today for example it happened the second time) the sound crashes and I have to reboot my machine to get sound back. I found this in the logs: pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead I cannot reproduce it, it happens during watching Youtube, playing Minecraft, VLC,... This bug is pretty annoying, because I have to reboot the machine, every single time :) I had not have this problem with 9.0 and it is a fresh install. Fix: Reboot the machine.

OK I think I've got it. At this time I am not sure which of these two settings has fixed the issue, but I've changed the following: # /boot/device.hints hint.hdac.0.msi="0" # /etc/sysctl.conf dev.hdac.0.polling=1 So far so good, no driver crashing until now =). I will do further testing to find out which of these did the trick :).
Should this ticket be closed? Or is there something that you found in the hda(4) sound driver that we should look into? Also, minecraft-client has been updated, if that's of any interest to you.
