ACK. For example soundcards with a C-Media CMI 8738/8768 chip
are reported to not do any resampling.
Another thing to take care of is Alsa: In the default configuration
Alsa uses the dmix plugin which does resampling to 48kHz. The easiest
solution around this (if you don't need dmix) is to change the default
device to your (hardware) soundcard:
/etc/asound.conf:
pcm.!default {
type hw
card 0
device 0
}
ctl.!default {
type hw
card 0
}
Of course you might also tell applications to use another playback
device, for example by setting MPLAYER_AO_DEV_OPTS to "device=hw=0,0"
in freevo's local_conf.py.
so long,
Hias
