Sound / iOS / Headphone socket only - why?

(Mark Westwood) #1


I’m trying to use zwift on my iphone 6.  For some reason, I only get sound if I plug a headphone jack in (i.e. it doesn’t work through iphones own speakers) - and no sound if I have a HDMI adaptor.  Any ideas?  I’m not trying to use Airplay as others who have reported sound problems.
