What I have read on android-hilfe.de it is a hardware problem and does not happen on all devices.

Consensus was to swap the device.

There you will even find a recording that exemplifies the problem. Not nice ...

I am glad I do not have this problem.

Thank you for answer
Is it better to repair or refund, and bought another?
I hope that in one store there will be not more corrupt.
I wish you that you do not happen :)

I can not answer that.

Some people had problems with SONY service. Others got a replacement with the same fault. The happier ones seemed to opt for a refund.

BTW What ROM version do you have?
Latest available today is 28.0.A.7.24

It might be worth a try (see anfalanl's post above) to flash the latest version.

My Z4 has exactly the same problem,
I was so disappointed by the quality ... (compare to my Z2, where the sound was good) .... I just thought the loudspeakers were bad ....
It is indeed an horrible white noise ... It is even louder than the music or the video, when the sound is really low...
Thank you for posting your problem, I know I'm not the only one ....

Contact CZC.cz when you have the Device buying form it.

Downgrade Firmware not needet. The Problem not the Firmware. The Device is defective.

Some Sony Z4 Tab have this Bug.

The Dealer have 30 Days to Repair OR exchange the Device.
If not (Time longer) you can cancel the Buying and Dealer must give Money Back.

See czech warranty Law.

Does someone has a tablet where he cannot hear it, especially when the sound is really low ?
I have such a tablet (SGP712 Wifi). I am on a newer firmware 28.0.A.7.24 (OK right now on AOSP) and I bet the OP is on 28.0.A.6.2

I suggested he should do an upgrade of the firmware but I am not his video guy ...

The "solution" he found maybe not the best but at least he lost no money.

IMHO the tablet DOES HAVE a high noise floor (inherent in design?).

Coupled with that, some tablets seem to have additional "crackling" when playing sound (mine does not).
