Hi folks, looking for a bit of help, i,m unable to listen to any music or watch any movies on my laptop the sound is badly distorted and after a while i,m left with the dreaded blue screen with this message.

driver not less or equal.

stop.= 0x000000d1 (0xA9E7E000,0x000000002,0x00000000,0x0AAF4D298)

CHAUD .sys address AAF4D298 base at AAF2B000,date stamp 44452ff0.

Many Thanks.

 

Bugcode 0xA - IRQL_NOT_LESS_OR_EQUAL
This is a fairly common BSOD that occurs when a driver has illegally accessed a memory location while NT is operating at a specific IRQL. This is a driver coding error, akin to trying to access an invalid memory location.
Parameters:
1 - memory location that was referenced
2 - IRQL at time of reference
3 - 0 == read, 1 == write
4 - code addressed which referenced memory
Recovery/Workaround:
There is none. This is a fatal error and is a driver coding error.

You can also get your BSOD auto-analysed at the Microsoft® Online Crash Analysis. If you experience a Blue Screen crash event, or Stop error, while using Microsoft Windows, you can upload the error report to this site for analysis.

 

This kind of technical information isn't helpful for anyone.

We dont need Microsoft OCA (and their 60-90 day turnaround for results), because we have a readme to do it yourself here.

That is an audio driver problem (CHAUD.sys). Look for upgraded drivers, or reinstall the current ones.

 

Cheers guys.......Thanks for the help..
