I get a lot of static-like noise when dmix resamples audio with a USB
DAC I'm trying out. When I have mpd resample internally with
libsamplerate, it sounds perfect. Can I get dmix to use libsamplerate
or disable dmix? One of the main programs I use with audio is miro
which doesn't allow you to specify an audio ouput device.
I tried this in /etc/asound.conf to disable dmix:
pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}
and tested with mplayer but that yielded no sound at all. I also tried this:
defaults.pcm.rate_converter "samplerate"
but that also yielded no sound from mplayer. Can I get around this static?

The following patch completely fixes this problem.

Does anyone know when this patch might show up in alsa-lib?
I applied this patch. It will be in next alsa-lib release.
