Redirect applications

[aksdb]

Is there currently some way to redirect sound output on the fly? Some kind of virtual master mixer maybe?

What I want to achieve is this: I have an onboard hdaudio device where I have my headset attached and a Creative Audigy 4 where I have my 5.1 speakers attached. For example when I listen to music it would be nice if I could just "switch it" to the other device. I know that PulseAudio could solve that problem, but it introduces a lot of other problems which I would like to avoid. So is there something within OSS4 that can handle this?

It is difficult to understand what you are going to do exactly, but I could do virtually everything (if not more) on ancient computers with OSS4 installed.
And it is made with a mouse click. I could speak with a frind by Skype, play music for him through Skype, and record all these, for example.

Hmm I try with more detail for my example:
I have music playing via Amarok to my default device /dev/dsp which is linked to my hdaudio pcm0. Now I want to lay down my headset and listen to the music on my 5.1 system, so I want Amarok to continue to play on my audigy's pcm0. In PA I can simply move the application from one slot to another. Is there any way to do that without pulseaudio? Is there maybe a way to have /dev/dsp link to a "virtual" OSS4 mixing device that redirects applications to whatever of my two soundcards I currently need?

I cannot understand. On my old box I have all sound on vmix and I can play everything simultaneously.
But if you have an USB headset and several soundcards, this simple method would not work.

EDIT: On ICH6 (or 7), I could switch from internal speakers to headset in vmix, or let them play simultaneoulsly, or connect everything and do what I want, except for that what I can do with Skype on ICH4 and old VIA card. But it is also possible to do the same with Intel HDA with another method.

EDIT: You see, vmix is in the kernel. If you would use anything like PulseAudio in the userland, the result would be the same: you would get another PulseAudio with the same sound quality.

EDIT: You may try JACK, it works with OSS4 (it would be better than PulseAudio), but JACK should be attached to vmix, which is attached to one soundcard.

As far as I know, this is not possible directly in OSS4 (I think it's possible to write an extension for moving a program between vmix instances, but there's no support for this now).

Thanks for that info. So at least there's a chance for it in the future (although developer time is rare, so I probably shouldn't hold my breath )

Try google some progs like sound capture.
