i have been experiencing sound issues for a few weeks now.
the sound disappears and sometimes it comes on by itself but more than not I have to stop and resume and I sometimes have to do this a few times.
Someitimes it is coupled with jerky playback as well (but not always) but presumably this may be because the system tries to keep video & audio in sinc so when sound is affected maybe has knock effect with video??
I have the RPI2 B via HDMIport
Can anyone shed a light?
