Public bug reported:
Binary package hint: alsa-utils
(Regarding alsa-utils 1.0.18-1ubuntu11 in Jaunty)
This does not give me sound:
$ aplay blah.wav
This does:
$ aplay -D front:CARD=Live,DEV=0 blah.wav
The argument to -D comes from the output of
$ aplay -L

(Note: This machine has an on-board via82xx audio chip [CARD=V8237] and a
separate SBLive card [CARD=Live]. The speakers are connected to the SBLive.)
I don't know which device is being used when aplay(1) is invoked without
a -D argument, but ALSA is properly defaulting to the SBLive, and other
multimedia programs (e.g. mpg321(1)) do get their sound out correctly.
Whatever aplay(1) is doing by default, it's not the right thing.
** Affects: alsa-utils (Ubuntu)
Importance: Undecided

No sound from aplay(1) due to improper default device selection
