Strange buzzing noise

Today my nvidia shield running kodi 16.1 with an Iptv66 subscription has started to do something weird while watching the service through the stalker client.

The screen freezes and there is an annoying buzzing sound. It may last anything from 2 seconds to 10 seconds then the sound stops and the screen does a little fast forward and catches up the lost picture. It's done its about 5 times today. I have not changed any settings and it's been running fine for over a month.

Has something changed?

Any suggestions anyone?

Thanks

Yeah there is issues with service happened to me this am

Thanks for confirming this. Much appreciated
