I've installed the alsa-plugins package on Gentoo which includes speex
and libsamplerate and rebooted, but I can't seem to set
defaults.pcm.rate_converter. My /etc/asound.conf file only contains
that line and I don't have an .asoundrc. Even with:
defaults.pcm.rate_converter "samplerate_best"
I still get static and my CPU is idle. When I use samplerate_best in
mpd my CPU is maxed. I've also tried samplerate, samplerate_medium,
speex, and speex-float-3. Do you know why this setting isn't taking
affect?
