Sound gone completely on AllCall W1

So today all of sudden remained without a sound. No sound in any app, in any settings
Did anyone encounter similar problem and how to fix it?
Thank you
The rest of the watch is working just perfect

sounds stupid but maybe you've put it on silence mode?

Thank You, but unfortunately not. Have found one vodeo in the internet. There is shown exactly mine problem, but not how to fix it.

it has to be the cable. also check for ota updates and i'll check if it is software.

So my skills are not good enough to access cables connected to speaker. Have open the back case and understood, that this is not for me. Sorry. OTA updates are not available on my watch, as it is rooted and SW update is disabled
