Need help finding a Quality VGA Switch that also switches audio

Anyways, I've been using my TV's VGA port and white red stereo inputs
for my dreamcast and my PC. But, I've just been getting tired of doing it manually since I only have one VGA port.


Through its VGA port my TV can Support

SVGA
XGA = 1024 x 768
WXGA = 1280 x 768
WXGA = 1360 x 768
SXGA = 1280 x 1024

Now I have searched the forums and found some solutions for switchers. However, still this would mean manually switching the audio each time.

I hook audio upto my TV from my computer and dreamcast with a 3.5mm headphone jack to red and white stereo jacks.

So I'm looking for the best and most inexpensive solution to a switch that switches between

My dreamcast & dreamcast audio
and
My PC / PC audio.

Anyone able to help me out?
