Preliminary testing indicates that this will work. You might make sure by cranking up the audio as high as it will go on both individually and making sure there's no cross-talk. I've seen some (cheap, crappy) sound cards that only have about -40dB isolation between Left and Right channels. If this is a one-off, and you are good to go with your current setup, great. If you're going to try to accurately reproduce it, be aware that some (cheap, crappy) sound cards don't have much isolation between the Left and Right channels.

Re: How to Play Two Audio streams to two different outputs?
We're wanting to use one Debian box to play two different audio streams to two different systems: one playing music-on-hold for our general telephone system, and one playing tips-and-updates for our Helpdesk phone system (for simplification purposes, you can just think of the two streams going to two different sets of speakers located in two different rooms). I figure we'll need two sound cards, each driving its own set of speakers. Not necessarily. You can reach it with just one, need only multiple outs ( e.g. terratec PHASE series...) But how do I get the system to play one audio stream on one sound card, and a different audio stream on a different card, at the same time? As a first guess, I think ardour would do. Just put the audio you are going to play on two (or more) tracks and configure two buses to send audio to separate card outputs. Assigning tracks to the desired bus (to a specific room/line/speakers) will do the rest. You will have full control on each audio track, meaning you can apply fx, eq, compressors and so on Running two different apps (or even the same app) under two different users is not a problem; I just need the audio to not mix between the two outputs. You don't need to run two apps, until you want to have full control on each one of them (stopping one track while playing the other one). Thanks! cheers hope this helps raffaele

I know there were a couple threads about this in recent history. one that came through just a couple days ago about using skype referenced the earlier thread as well. basically, as I understand it, you have to set some module parameters for the sound cards control how they are indexed and then set the outputs from the two sound programs to the different indexes. good luck A signature.asc Description: Digital signature
