I have 12 usb sound cards that I am using for a museum exhibit (outputs to many different speakers at the same time). Posted: Wed 5:28 pm Post subject: problems with many sound cards.
Linux, because I'd rather own a free OS than steal one that's not worth paying for. It actually sorted out a problem I had since removing my second sound card (I gave up with things coming out wrong, maybe now I can fix it to work right.)Īlmost forgot, I add a line for the joystick config as well, I only found this worked in kernel-2.6 not in /etc/modules.d/alsa. I must have spent weeks over the time I've been using Linux battling to get things to work right.
Alsa is powerful but so poorly documented most of that power is lost. Stop spending so much time on the computer and she might watch less soaps !!
Works really well if you have TV-out going and want to watch a movie on the TV and computer at the same time (Read: Girlfriend gets me to download horribly boring soap operas) Options snd-usb-audio index=1 id="headset" Options snd-intel8x0 index=0 id="onboard"
It appears that my index= entry in modules.d/alsa has no effect. I think that this is because the headset is detected during the usb initialisation - so nothing that I do in toload will help as this is read later in the boot. I've followed this, and many other threads and really thought that I'd got it, but I still get my sound defaulting to the USB headset (Plantronics DSP400) rather than the on-board card (intel8x0 on a Thinkpad T40p). Posted: Fri 12:27 pm Post subject: Still can't get on-board sound to trump USB headset Is there some way of duplicating the output to both sound cards, ie whatever is sent to the first one is also sent to the second one (I dont care about syncing it or anything like that) Very nice tutorial, while I had sound sort of working and other times I have had no problems with two sound cards, now I understand the configuration file a LOT better and everything is working perfectly

Now to find out how to get it to do dmix and full-duplex ^_^
I've got a Plantronics DSP500 USB headset set as the default and an onboard VIA 82xx driver that I use for the gameport. Windows on the other hand isn't even an option"īeautiful. Thanx for the answer, I set the default card in all applications to be the ZS one, so it does not matter (yet).

# Set this to the correct number of cards. Options snd-via82xx index=1 dxs_support=3 id="via" Options snd-usb-audio index=0 id="audigy" The trick was to configure each card individually and then merge the configs together.
