Re: [Alsa-user] speaker-test works but a aplay does not
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, the people of HifiBerry told me (see linked thread) that there is no "THE driver" and therefore I can not provide its source code. What I know that speaker-test -t wav -c 2 and mplayer -ao alsa:device=hw=1.0 /usr/share/sounds/alsa/Front_Right.wav work but aplay -D hw:1,0 /usr/share/sounds/alsa/Front_Right.wav and aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Right.wav don't. So for me it looks like there is something wrong with aplay. Because if there would be a fundamental problem with the driver, how could the other two programs (speaker-test is even bundled with aplay so I assume they don't do some crazy stuff) work? As aplay is used as default player in many places (e.g. in the text-to-speach-program I'm using) I would really appreciate if aplay would work too. I'm not an expert, therefor I can't check the code my self but if there is anything I can test to help to fix it, just let me know.

The internal sound device actually supports mono.
I don't know why the mono->stereo expansion does not work. This should
be handled automatically by the plug plugin. It would be possible to
explicitly disable this when compiling alsa-lib, but Debian does not do
this.
Please try putting this into your ~/.asoundrc:
pcm.stereoonly {
type hw
card 0
channels 2
}
and then running "aplay -v -D plug:stereoonly /.../Front_Center.wav".
Does it work? Does it expand the file to two channels?

Clemens

This is as expected as the HifiBerry card is card1, its parameters given in /proc/asound/card1/pcm0p/sub0/hw_params are access: RW_INTERLEAVED format: S16_LE subformat: STD channels: 2 rate: 48000 (48000/1) period_size: 32768 buffer_size: 131072 The differences to the values prompted in the error of aplay /usr/share/sounds/alsa/Front_Right.wav seem to be the number of channels and period_size and buffer_size. If I just run speaker test with one channel (default) speaker-test -t wav I also get a similar error like aplay: speaker-test 1.0.28 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 16 to 131072 Period size range from 8 to 65536 Using max buffer size 131072 Periods = 4 Unable to set hw params for playback: Invalid argument Setting of hwparams failed: Invalid argument So the problem seems to be the number of channels. I therefore tried to also set it explicitly for aplay but aplay --channels=2 /usr/share/sounds/alsa/Front_Right.wav still didn't work and gave "CHANNELS: 1" in the error. I hope that there is a way to fix it because it is a bit wired, that I can play mp3 files etc but no simple wav files.

Re: [Alsa-user] speaker-test works but a aplay does not
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Right.wav gives Playing WAVE '/usr/share/sounds/alsa/Front_Right.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono aplay: set_params:1297: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 16 CHANNELS: 1 RATE: 48000 PERIOD_TIME: 125000 PERIOD_SIZE: 6000 PERIOD_BYTES: 12000 PERIODS: 4 BUFFER_TIME: 50 BUFFER_SIZE: 24000 BUFFER_BYTES: 48000 TICK_TIME: 0 So the same like if I just called aplay /usr/share/sounds/alsa/Front_Right.wav What else could explain the difference to the working speaker-test -t wav -c 2 ?

If yes, are there any other definitions in /etc/asound.conf or ~/.asoundrc?
