Since the new Air doesn't have optical digital out anymore I am no longer able to hook it up to my system to transport multichannel audio... Does anyone have a good solution that is buyable from Europe? I have bought 2 USB sound cards with optical audio out, but both are incapable of pass through so they are useless and going to Ebay... It seems they support HDMI Audio out, but is that not restricted to Stereo also (on the Air)? If it isn't it should be quite easy to get the two pins from the HDMI connector and get the digital signal onto a normal RCA plug, but then it still isn't optical and my whole system is based on optical toslinks :/ Any ideas?
