No sound in King's Bounty english version

[uuulala]

well, no solution works for me. No sound in Kings Bounty. It is the first and only game I have this difficulty.

so no sound after default.ini patching.

I have even upgraded DX.... no sound still.
I have installed german version. no sound.
I have reinstalled and rebooted, several times. no sound.
I have activated and deactivated sound several times in several configs. no sound.
I have started new campaigns. no sound.

Any other idea?
