BTW I am using the an es1371, AC97 type soundcard.
OK, after compiling and installing the latest Alsa lib and drivers I set about
creating a .asoundrc file. Here is what I put in it from the example shown below...
pcm.dsnoopy {
type dsnoop
ipc_key 5978293
ipc_key_add_uid yes
slave {
pcm ",0"
}
bindings {
0 0
1 1
}
}
Now I don't feel easy about this because I have no idea what ipc_key means or where
the magic number came from. I just copied it from the example of the ICE1712 (see link
in previous message in thread quoted below).
When I get Helix Producer to query what sound/capture cards are availble it still only
reports one sound card...
$producer -pd
Helix(TM) DNA Producer 9.1 Copyright (c) RealNetworks, Inc. 1995-2003. All rights
reserved.
VIDEO
Device 00: BT878(Hauppauge (bt878)) /dev/video0
Port 00: Television
Port 01: Composite1
Port 02: S-Video
Port 03: Composite3
AUDIO
Device 00: TriTech TR A5 /dev/dsp
Port 00: line
Port 01: mic
Port 02: cd
Port 03: igain
Port 04: line1
Port 05: phin
Port 06: video
If I try running two instances of Producer the second one just hangs.
I am a little lost with the lack of documentation in the Alsa wiki. Do I need to add
stuff into the modules.conf file? How do I get this thing to work?
Regards,
Simon B.

The latest ALSA version has the dsnoop plugin for this. Somebody forgot to
create the link to the documentation, but there is an example at
