Sound drop out for second every 30 secs

[Steve1938]

As per title, sound drops out. No pattern. Sony TV, don't know model. No sound bar or external speakers. Superfast plus broadband. Happens on all platforms.

Don't want to start playing with engineers setting etc

Any advice? Has the recent outage been an issue? Only happened recently.

[Chodley]

Internet outage not relevant

most likely dodgy hdmi cable

what audio output setting?

[Steve1938]

Normal? Not Dolby digi, no speakers attached.

[Chodley]

Most TVs can handle DD. Worth a try just to see what happens.

Chodley, Tried this but no luck. There does appear to be an issue with my Broadband so waiting for Openreach to get in touch. Glitch also on the mini box upstairs although a bit less? Who know? Thx anyway. 

[Chodley]

Potentially a networking issue could make the Q processor get overloaded but I'd be very surprised if there's any link there.

[Steve1938]

Pattern is it Drops at 1 & 2 minute intervals alternately on pretty much all platforms?

[Steve1938]

Changed hdmi cable & still there. Normal & Dolby. Changed on & off a few times & nothing.
