GA-EP45-UD3R + Xonar DX = PCM Over 48khz screwed up

GA-EP45-UD3R + Xonar DX = PCM Over 48khz screwed up
« on: February 18, 2011, 05:08:01 pm »
Hello all, has anyone out there paired up these two?

My setup is:
Q6600
GA-EP45-UD3R
4GB Gskill 8500CL6D-4GBNQ
XFX 5870
Corsair HX620
Asus Xonar DX

I'm using the latest bios F12, and using the asus control panel when I chose anything over 48khz pcm sound goes really slow and cracked.

This wasnt happening with the F4 bios, but gigabyte added some needed fixes for memory in the F12 update and Im risking stability if I do a rollback.

Anyone have a clue?

Hi and welcome to the Gigabyte Forum.

Apart from reflashing back to an earlier BIOS the only other thing I can think of is a latency problem.

Download and run dpclatency checker from  http://www.thesycon.de/deu/latency_check.shtml

The problem is easilly fixed but finding the culprit can be more troublesome. Latency is caused by bad programming generally. There are various rules for how a program should access the core and if it doesn't follow these rules it can result in the core not being released for the next operation and this causes a bottleneck that backs up. The biggest headache from our perspective is that we have to find the rogue program/driver.

The best way to tackle this is to go to Task Manager and then in the Processes section stop all the processes that are not required for Windows to run. If you do this one at a time until you find the one that is causing the trouble. Then depending on what it is as to how you tackle the repair.

If none of that works you would need to go to Device Manager and disable all the devices not needed to run the system. Then you can enable them one at a time and again see which one causes the problem.

Have fun!

Thanks! It was a latency problem, I resolved it by flashing the bios of the sound card, I somehow missed it when looking at asus drivers.


Thanks

It is usually a driver or firmware problem but sometimes can be a devil to track down.
