iPhone 6S+ on 9.3.1 Anyone else having new problems with poor sound quality and non-responsive volume control? I now also have both "iPhone" and "iPhone speaker" listed under audio output. The poor sound quality persisted with multiple apps including safari, with both the external speakers and headphones. The poor sound quality resolved once I restarted the device however the wonky control persists. Not having the ability to control the volume is driving me nuts! Anyone else have this issue?
