Windows 7: weird sound issue

i downloaded a video file with ac3 soundtrack,cause i am using
only 2 speakers i changed the ffdshow to swap channels so i can
hear the ac3 in stereo.
when i tried to go back it is stuck on emulating dolby digital
on every file i try , wav, mp3, divx video in stereo.
tried to uinstall klie and audio drivers with REVo.
still the same shit happens.



HELP

Please watch your language here this is a pg site, though I understand your frustration.

I would make sure your current codec pack is completely removed and try replacing it with this
CCCP - Combined Community Codec Pack

At the end of the installation for that codec pack it gives you the option to 'reset all settings'. I would use that feature then (it will also update your ffdshow to the latest)

Anyhow that's just my first thought.
If nothing else hopefully the reset all settings feature provided by cccp will set ffdshow back to defaults for you.

sorry, this is a major issue for me cause sound is my occupation.
i will try what you suggested though i did re installed K LITE and did a reset...

klite has been problematic on some win 7 systems for me. though it does seem to work fine on others.

You can also always get the codecs and additionals you need from freecodecs.com instead of relying on packs that always wind up installing tons of stuff you don't need along with the stuff you do need.
Codecs.com :: Download latest audio codecs, video codecs, codec packs and tools, FREE!

problem is the entire sound on my system is defected , even on youtube,
which do not use the ffdshow codecs if i am not mistaking.

Have you attempted just removing the audio drivers in the device manager and rebooting the system to give them a chance to reset defaults?

i did uninstall al audio drivers

BTW CCCP didnt do the trick

Yeah at this point I'm not even certain the codecs are the source of your problem. What you changed has done something unexpected and neither my personal experience, nor my attempts to recreate the problem on my own machine are working here.

hope someone will come along and prevent me from
formatting my PC.
