Bravia KD49XH81 Sound “Boom” / Reverb

rroope — Tue, 22 Jun 2021 21:33:54 GMT

Hi Folks

Just bought a KD49XH81 Bravia Android TV. Picture is stunning, however there’s an annoying “bass boom” / reverb noise when watching TV, worse with music but does occur with normal speech also. It sounds like there are people talking in our hallway!

Been through all the settings and can’t seem to sort it, switching it to basic with surround off doesn’t help.

Any clues before it gets sent back as it’s far too annoying to keep!

Does this happen on the latest software version for you?

Yes, that’s made no difference. Sony support want a video but it’s proving impossible to do it! Rather disappointed ☹️

Change speaker settings from Table Top to Wall mounted or visa versa...it might also be what you have it standing on, a tin table, glass table and something on the walls, picture frames, curtain rails. If you can move it's position and see if it continues.

Try the suggestion by Eskimosony and if it doesn't work, give the video another shot. @rroope

Thanks for the continued support folks.

I’ve tried the switching of settings to wall mounted, no difference. I’ll try putting the TV on the floor and see.

I’m a vehicle “specialist”, the fault sounds a bit like a blown speaker / speaker isn’t mounted right and on certain sounds it makes the noise.

Does this happen on any application as well? Do you hear like a vibration if you raise the volume? Or does it sound like the sound is coming from a "Hallway" kind. If this happens all apps and contents, I'd recommend contacting the Sony support team using the link here.

I have just purchased KD43X81J Sony TV and experiencing exactly the same noise distortion of bass sounds. Sometimes it sounds like hearing a microphone in gusty winds.
I understand there seems to be a liking for heavy bass sounds a la cinema but we find it very distracting

I’m watching a tennis match at the moment and it sounds like someone is playing a didgeridoo in the background.
awaiting delivery of Sony sound bar this Friday!! Hoping this will solve problem , but any other advice would be great.

That sounds like the Mic is on listening for "OK Google" switch it off in settings...Settings/"OK Google" Detection/Off...See if that helps

Sorry. Problem not solved. Watched/listened to other programmes and still getting exaggerated and distorted bass sounds on voice and music.

Maybe have a look at your settings and make sure it's set how you like, Dolby, Cinema, Standard...whatever and make sure you have no effects on that could be causing it, Stadium, Concert Hall etc if your TV has those. Lastly try a Bluray or iPlayer, Google TV a digital source that is not Live TV, you mentioned tennis, there could well be wind noise and someone playing a digeredoo in the background!! Oh and this may sound mad but make sure you haven't got any weird 3rd party apps installed, make sure they are the factory reset apps, you know the ones that it comes with. I've had loads of trouble with a 3rd party app I installed that effectively broke Android on my TV. Other than that I think you may have to send it back.

We have recently bought a Sony Bravia TV and have exactly the same problem. During certain programs there is a constant bass boom and like you say even on some speech. It sounds like someone is parked outside in a car with loud bass playing. Tried turning bass down to minimum on GE but it does not make a difference. Tried everything else but no improvement. Very annoying and to be honest regret buying the TV as it spoils so much viewing.

SONY really should be providing a software update or at least acknowledging this issue! We seem to have adjusted it down so that it isn’t as noticeable; either that or we’ve just got use to it?

We have set tv sound to wall mounted and put auto sound level on plus set two lowest base levels to minimum. The sound is now a lot quieter but feels dampened down a bit. Haven’t really watched any programs where the bass has been a problem so will see how it goes.
Completely agree with you about the software update as it shouldn’t be this difficult and I don’t feel that I am getting the best out of the tv.

Hey @rroope, have you tried to reset the Sound settings? also, have you made sure that your TV software is up to date?

I have the same issue though. Surely it must be a common problem.
