Does anyone have an issue with the volume controls on podcasts? Sometimes when playing music or a podcast in the Xbox music my volume buttons don't raise or lower the volume. Also sometimes the podcasts or music will play very low like its on 5 and I have to start another cast or track to (reset) the volume . But once I get that volume set the controls usually becomes unresponsive unless I power down the phone. I'm on my 4th Lumia 920 and this happened on everyone one and all the phones were new phones.
