Hello
I need to create a "virtual microphone" for some tests of systems using
alsa. The application that is tested is only able to use "default" devices.
I created this .asoundrc file
pcm.audinp {
type file
slave.pcm "hw:0,0"
file /dev/null
infile /home/

aplay and arecord are not aware of those parameters in asound.conf.
They just see a stream of 1s and 0s. You have to tell them how to
interpret
Last version come with Alsa support (configure with --enable-mp4live-alsa)
ALSAaudio_alsa_source.cpp
in fact I've used Alsa, and it works perfect using "default" device.
But file device doesnt :(

Except that mp4live does not use alsa, it uses oss if I read the data right
well... I really want to use another application(mp4live)... not arecord.
So this application just ask me for : "sample rate", "channels" and
what Alsa device to use.
I've tell it "plugfile" device, 44100 as sample rate, and stereo(2
channels). As you can see I cannot specify the format.

I know... and that's the reason why I can specify that, using the asound.conf.
The source audio file is in 16 bit, 44100, stereo... but when I
record with arecord, it does with 8bit, 8k, mono.
So I must change this before arecord "record" the audio... where? .. I
suppose this should be in asound

Hi list
I've asked help before about file plugin, and it does work fine.
But I need something more. The raw file from which I'm reading audio is:
Signed 16 bit Little Endian, 44100 hz, 2 channels.
I've configured asound.conf this way:
pcm.plugfile{
type plug
slave {
Wrong format of your audio file? Do you know what your application expects?

I dont want to use aplay or arecord.
I got mp4live (as file player), and want to read audio with this application.
I've passed the param "infile:/home/carlos/record.raw"
The problem is that mp4live shows an error:
mp4live: pcm_params.c:2351: sndrv_pcm_hw_params: Assertion `err >= 0' failed.

This works:
pcm.infile {
@args [ FILE ]
@args.FILE {
type string
}
type file
slave {
I've spend so many days trying to make the file plugin to work. I've
read the pcm_plugins documentation and Everything everywhere, but no
luck..
here is my asound.conf
pcm.player {
type plug
slave {pcm "fileplayer"}
}
pcm.fileplayer {
type file
slave null
