Clemens, Takashi,
Thanks for your response. I have two follow-up questions.
I am unable to play mu-law files.
ALSA does support mu-Law.
If I try
aplay file.wav
I get the error message
aplay: test_wavefile:726: can't play not PCM-coded WAVE-files
Aplay's module for reading .wav files does not support Mu-Law.
I should have mentioned that I had already tried to use the -f FORMAT
before I wrote my original request, but that it fails with the following
error:
aplay -t raw -f MU_LAW -r 8000 file.ulaw
Playing raw data 'file.ulaw' : Mu-Law, Rate 8000 Hz, Mono
aplay: set_params:896: Sample format non available
The standard (sox-based) "play" command works:
play -t raw -s b -f U -r 8000 file.ulaw
What I'm trying to understand is:
(a) Why does aplay fail?
(b) How can I create a plug-in entry that plays mu-law? The
documentation says that a mu-law plug-in can convert mu-law to linear
and vice-versa, but it does not explain *how* to set that up, either way.
