Don't set AVAudioSession category #8

Closed ndbroadbent closed 9 years ago

This doesn't seem to be necessary, and can screw up AVCaptureSessions - specifically, subsequent calls to AVCaptureMovieFileOutput#startRecordingToOutputFileURL

Fixes #7

Are you sure it's not needed? I thought it was necessary to not affect the rest of the system's audio (e.g. currently playing music).

I'm not sure, but I'm already setting it to AVAudioSessionCategoryAmbient in my app. It seems that setting it again screws up my AVCaptureSession, for some reason, and I can no longer record videos. But also, we aren't actually changing the volume here, since it's being set back to the previous value?

Anyway, that's ok, my case is probably a pretty obscure bug, so I'm happy to just use a fork for now. Maybe we can wait until either Apple fixes it, or someone else reports the same issue.
