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.
When I run mp4live it says:
mp4live: pcm_params.c:2351: sndrv_pcm_hw_params: Assertion `err >= 0' failed.
I dont know what to do.
Thanks
