Audio Is Not Synced With Video - Perhaps a Driver Prpblem?

I have a Dell Optiplex 9010, I7 with 32 GM Ram & 500 GB HDD, on to which I recently installed a copy of Windows 7 SP-1 from a Windows installation disk and that I was able to authenticate with Microsoft. I believe that I have a driver problem because downloaded video from You-Tube or Rumble by using Gihosoft Tubeget has audio not synced with the video. I have used the Gihosoft Tubeget software on a different Windows 7 machine and it works without difficulty. The sound is set to high definition audio and plays streaming video from websites without difficulty. The out-of-sync problem occurs with a different players including VLC. Any ideas or suggestions would be appreciated. Thank you.

Try the free and open source YouTube Downloader here just for YouTube videos and tell me if the videos are still out of sync. I have a felling they won't be and if that's the case the software you're using now is bunk or you have to perhaps adjust some settings in your software options.

You download the zip and extract.

YouTube Downloader is made by a guy in Ukraine, and as we know his country is being attacked, so when you first use it it'll pop up a message... It doesn't bother me myself, it works great for what it does and I have used it many times with great success.

Prior to receiving your response, I continued to search for audio/video players and drivers for my desktop. I downloaded and installed GOM player and during the installation it displayed a notice that my video driver was outdated and that the software installation would fix the problem. After the installation was complete, I found that the audio and video tracks were synced and that the video images were sharper. While I did not find an updated driver for the GPU, this player will meet my needs and has corrected the problem. Thank you for responding to my posting.
