Hi, I just found out that the Macbook Air does not have the combined optical out port like the MacBook Pro. I am currently looking for a cheap solution to get optical TOSLINK or coaxial signal to my receiver which has no HDMI port. I googled quite a bit and was shocked that I could not find a solution. Really, no one has found a solution for this yet? I mean there just has to be an external soundcard with Bitstream-Passtrough or some kind of HDMI to TOSLINK audio adapter or something? I found some USB adapters, but it seems the 5.1 only works on windows, Mac ist stereo only. WTF? Please tell me that I will be able to get my delicious 5.1 from my new MacBook Air when it arrives, or I will have to send it back and wait for the new thin MacBook Pro 13"!
