Is there a way to playback (true) stereo audio (with seperate left and right channel) files during a phone call?
I'm not trying to make the callee hearing any of the stuff playing on my phone. I just try to playback a song while being on the phone (headset plugged in).
It seems that the iPhone switches to some kind of "joint stereo" mode, where it mixes L and R channel into a single one while the call is taking place.
Is there some option to prevent the iPhone from doing so? Is there an alternative music player for iOS that will render stereo audio as intended?
