Strange echo/reverb on all audio
In the middle of watching a film on Netflix there is now a strange echo or reverb on everything I watch on apple tv, Netflix and iTunes, also streaming music from computer through iTunes. Tried restart, putting sound effects on and off, sound check on and off, Dolby is off.
Thanks,
Gunnar
