It's not a problem, it's common practice to transmit stereo via IR - although in more recent years they have all moved to RF, due to IR being 'line of sight'. IR isn't too bad for headphones, but for speakers is more of a concern.
i've found some projects similar to this but they used 2 FM transmitter & 2 FM receiver modules, one for the left and one for the right channel to transmit and receive stereo.
im planning to use a multiplexer to transmit in stereo. would it still work the same as its 2 Tx and 2 Rx counterpart??
maybe its impossible to transmit multiplexed audio signal through IR because even SONY resorted to using 2 separate carriers for each channel...what do you think??
anybody here who's an expert in the field of wireless communications, specifically Infrared transmission...really need help here... ei, nigel, do you know anyone who i could consult to regarding this?
Multiplexing is probably a lot more trouble than separate channels. Even old Radio Shack can get you a set of IR headphones with the transmitter for around twenty bucks.

Why do you want to multiplex it?, the Sony dual carrier method seems simpler and more effective. Multiplexing was only a crude method of adding stereo to an existing mono standard, whilst maintaining compatability with existing mono receivers.
