I can do:
cat < /dev/sound/dsp > /dev/sound/dsp
and get a few seconds delayed echo of what is going on, as I would expect.
However, if I try to use anything more complicated, it locks up my system
- no keyboard, no network, needs to be hard booted.
The programs I have tried are "rec" which comes with sox-12.17.1 and a
downloaded utility called voice chat.
What happens is: the recording happens, but when the program ends, either
by itself or by being killed, the system locks up.
So maybe this is something to do with restoring settings at the end of the
recording?
Playback happens with no problem.
Below is the lspci output for the sound system, if it is of any use.
If there is any more info anyone wants, please ask.
