I'm running PCLinuxOS, and it does not come with .asoundrc. Some time
ago I asked here for some help to get
sound to come out of BOTH the Intel on-board sound decoder and the
GeForce NVidia HDMI port at the same
time all the time. (The NVidia card has its own sound decoder.) If I
had .asoundrc, would that help, and if so, what
should the script be?

Dear Doug!
Below are the hints I could manage to scramble together during your last troubleshooting, - I don't know if they are still useful?
Regards, Anders
I found a version of it here:
http://wiki.linuxquestions.org/wiki/M-Audio_Quattro
although it mentions /root/.asoundrc as proper placement which I would not recommend.
The idea is to create a "multi" device from your two hardware devices (e.g. hw:0,0 and hw:1,0) as described for the Quattro. Then create a "plug" device for handling automatic conversion (your software might not support the precise format needed by the "multi" device). In the example there is a routing table for the "plug" device consisting of expressions like "ttable.0.0 1;"
Those _expression_ mean something like "route input nr 0 to output nr 0 with level 1". Channels are numbered from 0. By doing something like
ttable.0.0 1;
ttable.1.1 1;
ttable.0.2 1;
ttable.1.3 1;
you duplicate what is coming on the first two channels from your software to the two output channel pairs. If you have setup the "multi" device properly that would mean sound out on both devices. There are a number of pitfalls that may need to be avoided, but give it a go and shout back if you get stuck!
Regards,
/A

You put it in the alsa settings file, which is either ~/.asoundrc if you want setting to apply only to one user (namely you) or /etc/asound.conf if you want system wide settings. The latter needs root access. It may be that neither of them exists in which case you have to create them e.g. by saving the proposed setting into a new file.
I have not tested 'copy' myself but there is another function in alsa which allows syncing of multiple sound cards, called 'multi'. I have used an excellent how-to to get an m-audio Quattro USB running on alsa that uses 'multi' - I'll see if I can dig up the link...

Thank you, Anders. I would really appreciate it you can find it.
