The case:
Clean install of Win 7 64 bit using latest drivers / bios / firmware / patches etc for all components / programs (Asus Xonar 1.3 ( 7.12.8.1775), TMT 3 (160), Win 7 64 (Final), ATI 4200/785G (9.10)).
Installed Powerstrip 3.87
Locked @ 23,976, 50 and 60 Hz (single monitor).
Bitstream works fine @ 50 – 60 but not @ 23,976!
Every 10-30 seconds I see momentarily the DTS Master Audio logo lightning up but it cannot ‘stay synced’.
As I am working with these things for some months now, I am 100% sure that it is not a matter of something not set upped right.
I had no problem with all of my previous setups (previous one (changes): ΑΤΙ 4550, Vista 64, Previous version of Powerstrip).
Any ideas what could be going wrong?
Actually I have many but I would like to know for starters if someone else with a similar setup (Win 7 (32 or 64) / ATI GPU / 23,976 (not 24!) / TMT 3) got it working.
