Sound Loopback Test - No operations reported in timeout period

[bahlul]

I am testing a computer system with Intel Core2 Duo and IDT's audio CODEC. I am conducting a 20min test run (i.e. CPU, serial, USB, sound, etc.) using BurnInTest 6.0 Build 1019 and I notice that the Sound Loopback test (5% distortion setting) stops operations just after a couple of minutes. The other tests continue to run normally. Changing the test load dutycycle didn't help:

If I just run the Sound loopback test by itself, it doesn't stop prematurely and there are no errors.

I switched to the newer build 1019 because when I was using build 1008 there were intermittent sound corruption errors (but note I never saw the sound test stop early). Below is test run from build 1008:

Please provide suggestions regarding this issue that I am seeing with the 1019 build.

The "No operations reported in timeout period" occurs when the operations counter for the test stops increasing for at least 8 minutes. This may be a device driver issue, like a crash and restart. Does the audio graph show anything during this period that the operations counter does not increase, or is it blank?

I would check you have the latest version of the audio device drivers, update and retry.

I would also try with just the sound test.

If the problem still occurs, could you please set Preferences->Logging to Activity trace level 2 and periodic logging to 1 minute. Run the test and send us the *.trace files showing the errors to the email address shown here:
