mplayer is using hw:0,0.
alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit (Little-Endian)
alsa-init: compiled for ALSA-1.0.3
alsa-init: soundcard set to hw:0
alsa-init: pcm opend in block-mode
alsa-init: chunksize set to 1024
alsa-init: current val=16, fragcount=16
alsa-init: got buffersize=65536
alsa9: 44100 Hz/2 channels/4 bpf/65536 bytes buffer/Signed 16 bit Little Endian
It doens't like plugwh:0,0:
alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit (Little-Endian)
alsa-init: compiled for ALSA-1.0.3
alsa-init: soundcard set to plughw
alsa-init: pcm opend in block-mode
alsa-init: unable to set periodsize: Invalid argument
Also my .asoundrc was very minimal:
pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}
Now I added:
pcm_slave.sl2 {
pcm "hw:0,0"
rate 48000
}
pcm.foobar {
type rate
slave sl2
}
But, again, MPlayer refuse to work:
alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit (Little-Endian)
alsa-init: compiled for ALSA-1.0.3
alsa-init: soundcard set to foobar
alsa-init: pcm opend in block-mode
alsa-init: unable to set periodsize: Invalid argument
aplay does recognise -Dfoobar (and work even without it).

Yep, it seems so :)
Btw, mplayer from CVS (checked out today) works nicely with -ao alsa1x:
alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit (Little-Endian)
alsa-init: compiled for ALSA-1.0.3
alsa-init: got device=0, subdevice=0
alsa-init: 1 soundcard found, using: hw:0,0
alsa-init: pcm opened in block-mode
alsa-init: chunksize set to 1024
alsa-init: fragcount=16
alsa-init: got buffersize=65536
alsa1x: 48000 Hz/2 channels/4 bpf/65536 bytes buffer/Signed 16 bit Little Endian
...
[resample] Changing sample rate to 48000Hz
[resample] Changing sample rate to 48000Hz
[resample] Using linear interpolation.
So my sound card accept sound only at 48000Hz but old mplayer didn't
notice that alsa-lib doesn't accept its request for 44100Hz. Correct?
thanks,
Luca
