No sounds when touching screen

[NaKsUtTaJa]

Hi

My tablet has a problem that it usually (not always but most of the time) disables all sounds when I touch the screen. Depending on how long I touched the screen the sounds return immideadly or few seconds after I let go. When the sounds return it plays some of the sounds that should have played when I was touching the screen.

Android version is 4.1.1 and model number of the tablet is rk30sdk.

Any ideas on how to solve this problem or how to get more information on what could be wrong is welcome.

Welcome to Android Central! It's probably an issue with the system or the hardware, and it's always difficult to troubleshoot these less common brands. I assume you've tried rebooting the device, correct? You could always try a full Factory Data Reset (typically from the Settings>Backup menu), but you'll lose all of your data, so make sure it's backed up.

Thx but tried those already

Any other ideas how to fix this or what to try. I'm still hoping it's not hardware problem.
