BSplayer plays video, no sound at all, reinstalling doesnt help.

[zappaman]

other players do play video & audio perfect, but for some reason bs player has stopped playing audio completely.

i have tried to remove all codecs + bsplayer + deleted bsplayer(webtech) folders from c:\program files\webtech and reinstalling just bsplayer and download codecs by its automatic codec downloader.

without any effect, bs player doesnt play any sound.
mute is not on and all other programs + players are playing all sounds normal.

when playing video ffdshow and haali mediasplitter shows up in taskbar

Tried to re-register quartz.dll
%windir%\system32\regsvr32 %windir%\system32\quartz.dll

successfully re-registered but didnt help.
