how to use speexrate or samplerate

[jiaxi]

the alsa-lib default use linear resample .And now we want to usb speexrate.
1. compile alsa-plugins-1.0.23.tar.bz2 and alsa-lib
2 in /usr/lib/alsa-lib we can get libasound_module_rate_speexrate.so
3 modify /etc/asound.com
defaults.pcm.rate_converter "speexrate"

but when we use aplay 48k.wav.
we can get the log:ALSA lib pcm_rate.c:1469snd_pcm_rate_open) Cannot find rate converter



# ls /usr/lib/alsa-lib/
libasound_module_ctl_arcam_av.a
libasound_module_ctl_arcam_av.so
libasound_module_ctl_oss.a

1/ You wrote that you compiled alsa-plugins-1.0.23.tar.bz2
Do you mean you emerged alsa-plugins with the speex use flag set ?

2/ Which kernel version are you running ? Latest kernel versions implement 1.0.25 alsa drivers and it is always better to ensure drivers/plugins/lib versions match.
Moreover 1.0.23 plugins and libs are no longer available under portage's tree.
