Rotatable sound setup?

[Ben]

OK Excuse my fantastic (!!) Paint Skills:
Link to image. (Basic layout of my bed room(not exactly to scale !!)).

Currently have my Sammy 26" connected to my PC, which has some aging Cambridge soundworks speakers (only front ones). The sammy is wall mounted and is the bigger rectangle near the 1 in the top image. My Bed is the big rectangle to the right.

What I would like to do is buy some speakers and amp with a "rotatable" setup. (and most likely a new soundcard that can output to the amp).
So when I'm sitting in front of the screen (like in the top image) i.e. at PC. the speakers are configured to be.
1) Front Left
2) Front Right.
3) Rear Right.
4) Rear Left.

And at a flick of a setting (and after pulling my TV out and rotating it towards my bed, like in the bottom image), I would like the speakers to be (for when lying in bed watching something)..
1) Front Right.
2) Rear Right.
3) Rear Left.
4) Front Left.

I'm guessing this sort of set up would also need different volumes for the speakers depending on their role at the time?

Is this possible? or would it be better to use some kind of software on the PC to do it?

It would be possible if you were using two different sources, but if the sources are the same I dont know of any off-the-shelf way of doing it.

Can I do this if I had 2 sound cards? both using optical? If so then all I'd need to do is switch the sound card that is being used to the one I have set up for the config I want.

If that is possible, what amp/speaker combo would be recommended for the task? (looking at £300-400 for price bracket)

Cheers

Basically, you need one "normal" input into the digital input (which will give you the correct way of having the speakers placed) and then for the reversed you would use the 6 channel input of your amp backwards to invert the speakers.

So in theory, I could use my current on board sound card, as it has both an Optical SPDIF and 3 Jacks for Front, Rear, and Centre/Sub. Set the SPDIF to be Digital Only, and then use MPC or VLC to select the SPDIF when I want one configuration, and normal processing when I want the other? (so I need 3 short jack to phono leads, and an optical cable).
I'll most likely need a better sound card for when using the Jacks.

As for the budget, £400 should get you a s/h AV amp of your choice plus a reasonable "lifestyle" speaker set like the Cantons or a set of M71is for front/rears and a centre to match, leaving you to scrape about for a sub when you next get paid

Any recommendations on a sub and amp?

Also being that I live in a flat, I can't really use expensive equipment to its full potential, which was why I put a price range of £300-£400 as I would have thought any more than that I wouldn't be getting my money's worth.

Hi guys, thanks for your input.
However, I don't think my room can be in a configuration to get an "optimal" setup.
The other wall side (from my bed, is taken up by a built in warddrobe and the door. And then I'm getting into the viewing distance being quite large for the 26" (talking about from the bed), and would probably require a much larger set.
The other option is having a smaller bed, which isn't really an option!

And yes, we have a 32" CRT in the lounge, so this isn't the "main" set.

The more I think about it, the more I'm leaning towards the Logitech 5.1 THX set for just under 200 quid. As it doesn't seem to be worth spending the extra money for the situation I'm in. Also they should be much better than my aging Cambridge Soundworks ones which only have the connections from the PC.
