[SW BFII] No or Incorrect DVD error messages.

[Deathpit]

I have troubles with Star Wars Battlefront II since I upgraded my Windows Vista Ultimate 64-bit to Windows 7 Professional 64-bit. There is a catch: the game worked fine on Vista Ultimate and game launcher able to recognized the DVD disc before start up. Now, it won't start up on Windows 7 Pro, none of no-CD patches and re-install the game helped and continued to throw up the error messages on me.
I replaced the IDE DVD drives with new eSATA DVD drive. Did the drive and SecurDisc do something with error messages?
I want to play SW BFII with new version of Conversion Pack so badly.

LucasArts Consumer Support isn't help a lot and don't bother to create a fix patch. Pandemic Studios, the game's developers, was shut down for good by morons from EA. Only opinion I had to purchase a digital version from Stream but I isn't ready to shell out the money until I get a fix.

Are any ways to bypass the annoying error messages? I will be happy if anyone can help me with best solution.

[EDIT] I tried a solution on stereo mix but I still got same error messages.

[EDIT] I found a problem. It was 1.1 patch which caused the game not able to recognize the DVD. I tested 1.0 version and it worked fine. After I patched it, the same problem came back with same error messages. I guess I have to take that problem and shove it up to LucasArts customer support. I am aready pissed off.
