Hi, Chuck: Part of the problem is that there are several ways to address the cards. There's the direct way. Here's an example: aplay -D hw:1,0 Then there's the plugin layer: aplay -D plughw:1,0 ecasound does it differenty, and I need to leave my computer for a few hours--so I'm going to rush through the rest. You want to use the plug layer because it will allow you to address all the devices on your card, midi ports for example. You might ultimately also want the jack-audio-connection-kit installed so that many apps can talk to your sound card at the same time, while maintaining low latency. Jack only does one card for now, though. More later. Chuck Hallenbeck writes: > Is anyone using two sound cards on one computer? I am trying to figure > out how one sends audio to a specific card.
