Ive searched for answers, but I havent found anything that helps me yet. I just bought an Airport express for the sole purpose of using airplay with a set of Swan M50s. I can usually get it to work fine with two different Iphones, but it hardly ever works with my cMBP (mid'12), and rarely works with my AppleTV. I have it set up in bridge mode and it is connected to my network. I can go into iTunes as well as the AppleTV and select the Express as my speaker selection, it just doesnt work. Usually I get a time out error on the MBP, and with the appleTV, it seems to try for a minute, then ultimately go back to sending audio to the TV, even though when I hold select, and go into the speaker selection, the express is still selected. It seems to work great with the iPhones, a little bit of lag initially, but nothing I cant live with. (it works with locally stored media, as well as youtube audio and Pandora on both phones) The concept of this unit is great, it just seems to be so unreliable that is unusable for the #1 purpose I bought it for, which is playing my appleTV audio to it. It works once in a while, usually after unplugging it and plugging it back in, but I dont want to have to do that at least once a day for it to work properly. Anyone have any ideas?
