Software used Nuendo 3.2, Wavelab and Liquid Edition 7.2

DC changes correctly, on the statusbar, with the used samplerate of the application: 44k1 and 48k.

Checking on an other machine I found that we are using 3.080 there with a working DC. Tried to backrev the new machine to 3.080 and surprise: DC is working again. Reving up to 3.081: DC stopped working. I checked this 2 times back and up reving with the same results.

We went from 3.079 to 3.080 on the digiface machine because we had serious problems with sync between audio and video on Liquid Edition 7.2 that went away with the use of 3.080 but these sync problems were not present with Nuendo at all......

Therefor I have the impression that more might be changed that the eye meets when I read the release notes.

Do you need any more information about hardware and/or software configuration?

Basic setup: XP with SP3, Audio card HDSP9632 with 1 AO4S-192 expansion card and latest flash update 154. 6 Analog channels are used to drive a surround speaker set. In TotalMix only Out 1-6 are routed to Analog out 1-6.

Playback is done with either Nuendo in a 6 channel surround mode or with Liquid Edition in a 6 channel surround mode. Both are using the ASIO interface only. All video work in 48k, audio in either 44k1, 48k or 96k.

DIGICheck in: Surround Audio Scope mode is running and looking at SOURCE> PLAYBACK of the appropriate 6 analog channels. The tick box: Set sample rate for ASIO inputs is not checked.

In this configuration with driver 3.081 DC is not showing any signal on the playback outputs, although the signals are there. Only if you use DIGICheck in: Global Level Meter mode you will see the output signals.

If you just change the driver back to 3.080 and put DIGICheck in: Surround Audio Scope. DC will work normally again and displays the output signals.

Only one of the software applications is started at all, therefor I do not think I am using multiclient playback in this case.

So I used your exact setup and it simply works - as expected. There must be something more going on. You might upload screenshots of all settings somewhere for further checking.

Before going to format the C-Drive I was able to analyze a couple of minidumps. It seems to point strongly in the direction of the combination DigiCheck with the HDSP driver. Please find below the results, you may find this usefull.

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: c0005000, memory referenced
Arg2: 0000001c, IRQL
Arg3: 00000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 804e820c, address which referenced memory
