My Moto Droid is rooted an I run a variety of ROMs. This has happened on several different ROMs.
I have my Droid in a Car Dock, and attached to my stereo's input jack via 3.5mm cable. I'm streaming Pandora, or listening to music stored on my Droid. It sounds awsome. Better than satellite radio. Then, I get a phone call. I answer, and talk on the phone. No problem, Music is paused and incoming audio is piped through my stereo.
However, when the call ends, and the music starts playing again, now it sounds like it's inside a tin can - no base, very quiet, sounds crappy.
It has done this several times. I've tried stopping (via Manage Apps)/re-starting the music App (Pandora, Music, 3, etc.) That doesn't help. I eventually just started re-booting the phone.
Does anyone know how to get the music to return to normal quality after a call?
