Re: [Alsa-devel] How do create a dummy device for recording audio? Does it exist already?

Alright, I did what you suggested, and real player comes up and connects
to the dummy sound card (I had to do a modprobe snd-pcm-oss and
snd-mixer-oss). However, I don't get a file called /tmp/file.raw.
You have to configure the program to use the PCM named file instead
of the default default.
However, Realplayer uses the OSS emulation through /dev/dsp0. To make
that work with your file device, add the following to the config
file:
pcm.dsp0 = file
and try to run realplayer with the aoss script from the alsa-oss
package.

Awesome! It works like a charm. Than you so much! The one thing that
doesn't work quite right is that I get the following error when
RealPlayer attempts to access the mixer:
ALSA lib control.c:601:(snd_ctl_open_noupdate) Invalid CTL mixer0
Is there a simple way to get it to control the mixer? Currently, I have
to bring up alsamixergui to turn up the volume.
Thanks again,

Do I have to do anything to make .asoundrc get reread?

what do I do with that bit of configuration data? I found the
/usr/share/alsa/alsa.conf, and there is a similar pcm.file entry
in that, but it seems to take parameters.
Put it into your ~/.asoundrc file, or into /etc/asound.conf for all
users.
Since I have no sound card, how do I configure my system to use
the dummy PCM driver and use the pcm.file plugin?
modprobe snd-dummy should work.
