Hello; Since Intel announced the discontinuation of interactive support (phone, email or chat ) for the D975XBX2 back in 2009; there will not be any future driver updates for newer operating systems, such as Windows 7 If you need assistance troubleshooting audio problem, check the following URL: http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#distorted
I have a DX48BT2 Board which Intel does not have a windows 7 64bit driver for IDT sound , So I used the vista 64 driver and installed it in compatability mode works fine.
I'll give that (or something LIKE that) a whirl......and see how it works out. I'd hate to go 'back' to Vista, just on principle. :-)
Thanks for getting back.......but, I've been on that page, and there's no help there for owners of the D975XBX2 using Windows 7.
My poor audio quality is with every source of sound emanating from my Intel board. CD.....DVD......headphones.....all programs.
For Intel to not even be able to SUGGEST a 'hard' cure or at least some options (roll back something/alternate driver/third party solution/add a sound card/use Vista/.........something, ANYTHING......is reprehensible.
How many of these boards did the company sell? Five or ten? I think perhaps a few more.
Please escalate to your supervisor.
