>Description:
When trying to play sound on this Acer notebook the kernel spits out
"pcm:play:0 play interrupt timeout, channel dead" messages.
pcm0: <Intel ICH6 (82801FB)> port 0xe100-0xe1ff,0xe200-0xe23f mem 0xd00c0000-0xd00c01ff,0xd00c0200-0xd00c02ff irq 11 at device 30.2 on pci0
pcm0: <Avance Logic ALC250 AC97 Codec>
At first glance the device is recognised correctly but as soon as you try to play any sound, the following message occurs.
pcm0:play:0: play interrupt timeout, channel dead
