I recently updated may alsa from 1.1.4.1 to 1.1.6. I now noticed that
aplay does not work properly (the same as 1.1.4.1) when reading the
sound file data from stdin. This might have something to do with the
recent change with reading the sound file header.
With the previous version of aplay, aplay would report:
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono
With 1.1.6, aplay reports:
Playing raw data 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
This results in static/noise output. If I explicitly add the '-f
S16_LE -r 22050' options to aplay, then it does play correctly.
Is this a known bug and is there a fix?
It works fine on my system.
% aplay test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
% aplay < ~/test/test.wav
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
% aplay --version
aplay: version 1.1.6 by Jaroslav Kysela <perex@xxxxxxxx>

Well, it does not work for me:
cat bird-calls.wav | /usr/bin/aplay -Dplughw:0 --
Playing raw data 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
^CAborted by signal Interrupt...
aplay: pcm_write:2051: write error: Interrupted system call
aplay -Dplughw:0 bird-calls.wav
Playing WAVE 'bird-calls.wav' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo
Looks like aplay may now have problems reading from stdin if stdin is a
pipe.
