No audio with WMP after I udgraded from 32bit to 64bit

Hello and thank you for taking the time to read this.

I have recently reformatted my computer and upgraded it from XP Home 32-Bit to XP Pro 64-Bit, everything seems to be great except that Windows Media Player 11 will not include audio when playing any of my videos or mp3 song files that are still on my external harddrive. All of the other audio and sound effects for Windows work flawlessly, so I know its not an issue with my speakers or volume control/muting.

I have a Creative Sound Blaster audio card and from what I can find I have no other on board audio card enabled. I updated the driver for the Multimedia Audio Controller with no luck, so I went back and uninstalled it in order to just leave my sound card by itself.

This is the first time I have posted on a forum asking for help with this problem but I have tried every suggestion I could find on other forums to fix this problem with still no luck.

I have tried different versions of the AC3 audio codecs, numerous XP Video Codec packs and even uninstalling and reinstalling WMP v. 11 and v. 10 a few different times. I have also tried a bunch of suggestions from other forums including configuring the AC3 patch and attempting anything else I could with the device manager with yet still no luck.

Sometimes after attempting some of these solutions I have restarted and watched a few videos and the audio works fine, but on further inspection and with more video/audio file opening, it goes back to silence within a few minutes again.

WMP is my player of choice, and I really would love to have it back working like it did before I upgraded. If anyone can offer any solutions or help me diagnose this problem it would be greatly appreciated. Thanks for your time.

 

There are a lot of programs that are not in 64 bit yet, although most of the newer PC's are 64 bit. And there's already talk about the next version of Windows (Windows 8) being 128 bit. If there is a lack of 64 bit programs now, how by 2012 will we be able to run 128 bit programs? But there is a 64 bit version of Windows Media Player, because I have it.
