I've searched around and thus far found no answer that I'm satisfied with for what is causing this. I run Pandora, its playing fine, hit home or switch applications and audio stops immediately. On my old phone I never had this issue. My old Droid was stolen and I modded this one exactly the same as that one with Cyanogen installed by using Rom Manager. With the old phone, it didn't matter what I was running, Pandora would stay running. I've tried doing the same thing with Last.fm and it stays running just fine, no crashing/freezing, no matter what I do. Any idea what could cause this? There were only 2 days between my old phone and new one so I doubt there was an update in there that would radically change the way the program works.
