Strange buzzing sound while playing media files
Yesterday I needed a tool for conversion of MOV files to WMV files and I found this program:
Free Convert MOV AVI to FLV Flash WMV Converter - Free software downloads and software reviews - CNET Download.com
During the install, it said that some of my media drivers were "obsolete" or something like that and offered to delete them from the registry. The dialog box said "Yes - recommended". I clicked "Yes" to all prompts - there were at least 15-20 of them. Then the program installer installed some codec packs. I am pretty sure that ffdshow and K-Lite were installed although I don't know which version. I think there was also some 3rd type of codec pack but I can't remember the name. It also installed some strange version of media player classic (1.3.1976.0).
Anyway, the program didn't actually work after installation, it was shareware and asked me for money to convert entire files. So I uninstalled it from the Control Panel/Programs.
Unfortunately, now I have a problem when playing ALL media files. It manifests as a strange intermittent buzzing sound during music playback (in Winamp, Windows media player and Foobar - they all have this problem). Also, the buzzing sound appears during playback of video files in KMPlayer or Windows Media Player (it seems that in WMP the problem is more pronounced).
The buzzing sound occurs unpredictably. There is no specific rule to when it will occur. So if I play a sound file 5 times, it will be heard at different places all 5 times. Also the frequency of its appearance varies: sometimes it can be heard only once or twice, sometimes many times.
I think it's obvious that this problem is caused by some faulty media codec. So does anyone have an idea how to remediate this problem? Can all media drivers be deinstalled and then reinstalled? What would be the correct procedure for doing this?
BTW. I can't do a system restore because System restore doesn't work on this PC for some time (that's another issue which I will ask about in a separate message). I also tried System Restore in Safe Mode but no luck.
I have Windows 7 64 bit OS.
Any suggestions are appreciated.
