I built a voip app and a stranger said the audio isn't playing on the Sony Xperia ZL (model c6506). The microphone works though. So taht means the Sony Xperia ZL user can speak and the other party can listen, but the Sony Xperia ZL user can't hear what the other party is saying.
I don't see an AVD option for a c6506 emulator/simulator. Is there anyway to debug for that specific model WITHOUT actually acquiring the phone? If not, then does anyone know if there's something specific about the C6506 that may cause the audio to not work?
My voip app is working fine for the S2, S3, S4, Note 1, Note 2, Sony Xperia Z, HTC Amaze, HTC One, Nexus 4 and Galaxy Nexus. Not sure what is so special about the C6506?
Other details: I'm using Linphone Core as the Sip library. I'm using asterisk 1.8 as the server. Everything else about my app is very straightforward. It's simply dial the userid of the person you'd like to call, then you can hang up.
