Switch audio channels during playback

[peterle]

Hi everybody!

I want to switch speaker channels during playback, i.e. assign left-front-channel to speaker S1, right-front-channel to speaker S2, etc., and then, on the fly, change it to left-front on S2, right-front on S3, etc.:

S1 TV S2
^
|
-> PC


S4 S3

I have a 4 Speaker Surround System (connected to my computer), a PC and a TV. When I watch a DVD from the PC (via TV-out) on the TV the speakers are set correctly (front left channel comes from the left front, etc.), but when I sit at the computer, everything is turned by 90°.

I searched the forum but couldn't find anything to answer my question.

Is there a utility or a hack or anything, that enables me to assign the internal channels to the hard-wired ones in the jacks?

Check the audio setting in control pannel. whether the speaker selection is correct or not. In the DVD software you are using select 4-channel output instead of 2 channel.

Hi sanjayk,

Thank you for your feedback. All settings are correctly set to 4-speaker mode. What I want to do is switch the speakers by 90 degrees on the click of a button. Right now I have surround when I sit at my computer, but when I watch a movie over the TV (which is coming from the PC via TV-out), obviously the front-channels are coming from the left, and the rear-channels from the right, as the TV is standing between two different speakers than the PC display is...

Now the question is: can I manually assign the 4 output channels to the 4 speakers?

If your sound card drivers don't support it, then no. Some sound cards will swap stereo channals to support reversed speaker placement, but not just shuffle everything to the right or left one speaker.

Thanks for the answer... Do you know of any sound-card that allows this? I was thinking about buying a Creative Labs, EAX-enabled card to replace my onboard sound-unit.

Does, for instance, the Creative Audigy 2 support this kind of speaker-mapping?

I doubt it. It is a pretty unique situation. They expect that you will either have a dedicated set of speakers for your PC, or a media centre type arrangement using the same screen as your entertainment centre. In either case there is no need to re-arrange the channel position.
