$ dmesg|grep pcm
pcm0: <Creative EMU10K1> port 0xe000-0xe01f irq 9 at device 11.0 on pci0

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm) Jan  8 2002 15:30:57
Installed devices:
pcm0: <Creative EMU10K1> at io 0xe000 irq 9 (4p/3r/0v channels duplex)

>Description:

Every time when I'm trying to record something with any program, the kernel
complains:

pcm0: record interrupt timeout, channel dead

`cat /dev/dsp' pauses for a second, gets no data from the record
source, then drops back to a prompt. Playback works fine. Recording works 
at least in 4.2 but broken since 4.4-R.

>How-To-Repeat:
Try to record with `cat /dev/dsp > file' or with something else.
