Summary: aplay/arecord cannot play/capture A_LAW
Description:
aplay/arecord can play MU_LAW and the sound card support MU_LAW and A_LAW
arecord -D hw:0,0 -f MU_LAW -t au -c 1 -r 8000 test.au
aplay -D hw:0,0 test.au
Try to use -t raw but the quality of A_LAW is very bad when compare with
MU_LAW
arecord -D hw:0,0 -f A_LAW -t raw -c 1 -r 8000 test.raw
aplay -D hw:0,0 test.raw

It's no Oops but the stack trace output from snd_assert(). It's a bug, of
course, though.
Anyway, PLEASE open another bug. This is out of the topic of this thread
-- "aplay/arecord cannot play/capture A_LAW".
And please show the ALSA version you're using. I cannot see the relevant
assert line found in the message.
