[solved]problems with alsa samplerate conversion

Since my E-mu 0202 USB is not fully supported by alsa and works fine only with 48000kHz streams,
I'm trying to set up software resampling but fail. every alsa app complains
alsa-lib: pcm_rate.c:1369:(snd_pcm_rate_open) Cannot find rate converter
here is my asound.conf

pcm.intel {type hw; card 0}
ctl.intel {type hw; card 0}

pcm.e-mu  {type hw; card 1}
ctl.e-mu  {type hw; card 1}

ctl.!default ctl.e-mu
pcm.my_rate{
  type rate
  slave{
        pcm "pcm.e-mu"
        rate 48000
        }
  converter "samplerate"
}

pcm.!default pcm.my_rate

Re: [solved]problems with alsa samplerate conversion

You need to install libsamplerate. A command you'll probably find useful:

pacman -S ladspa blop swh-plugins libsamplerate tap-plugins cmt

From my ~/.asoundrc

Re: [solved]problems with alsa samplerate conversion

still not working, does anyone have a clue?

I missed to install alsa-plugins from community
I thought it was shipped with alsa-lib since I hadn't find that package in extra.
