[Alsa-user] what provides libasound_module_pcm_plughw.so

[Matt G. <mat...@gm...>]

Hello,

I have an MAudio Audiophile 2496 PCI soundcard.  My goal is have
ALSA do as little as possible, and just pass the audio to the
hardware.

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: M2496 [M Audio Audiophile 24/96], device 0: ICE1712 multi [ICE1712 multi]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

So I started with this /etc/asound.conf to bypass dmix:

pcm.!default {
    type hw
    card 0
}
ctl.!default {
    type hw
    card 0
}

Unfortunately, it looks like I need to use plughw:

$ aplay 03_harvest.wav
Playing WAVE '03_harvest.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: set_params:954: Sample format non available

So I modified /etc/asound.conf slightly:

pcm.!default {
    type plughw
    card 0
}
ctl.!default {
    type plughw
    card 0
}

$ aplay 03_harvest.wav
ALSA lib pcm.c:2156:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_plughw.so
aplay: main:583: audio open error: No such file or directory

Building alsa-plugins-1.0.19 and alsa-lib-1.0.19 from source did not
result in the libasound_module_pcm_plughw.so library.  Where can I
obtain this file?

Thanks,
Matt
