STacSV64.exe IDT PC Audio using 50% of cpu

[Leo5311]

Hi!

SP43288 is the latest.

I had this problem and it was maxing out my CPU to 100%, overheating my DV5-1000US, firing up my fan at full blast, wasting my battery, and freaking me out. I quickly noticed that stacsv64.exe was the culprit in Task Manager and Resource Monitor. After reading the posts here I realized the only way out was:

** System Restore back to the state before the HP Health Check updated my IDT audio drivers/services/files. **

I executed above referenced System Restore to a state four days ago when this problem began to rear its ugly head, and the problem is GONE! -- at least from one reboot. I will report back if I have any STACSV64.EXE issues. It is so nice to see my CPU at 0-5% after rebooting.

After two full days of intensive use of my DV5-1000US I can assure you that the System Restore did the trick and resolved my problem.

YES...I had tried EVERYTHING, and only SP42549 fix worked for my HP Pavilion dv7-1232nr

Thank you all for finding that fix.

Even HP's site doesn't show it:

http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=2100&lc=en&dlc=en&cc=us&product=3802949&lang=en

you have to find it specifically via:

http://h10025.www1.hp.com/ewfrf/wc/genericSoftwareDownloadIndex?softwareitem=ob-69039-1&cc=ca&lc=en&... 

I've booted many times, with no loop now.

Agreed. Since installing SP42549 several weeks ago I've booted my DV71260 dozens of times without any CPU incidents. Of all the drivers discussed in this thread, only SP42549 seems to permanently resolve the problem. So far HP Health Check hasn't tried to update it but I've got a backup copy just in case ;-)

I have just bought a brand new HP DV6, noticed it when setting it up, stacsv.exe running at 50% constantly and all other symptoms mentioned- disabling restarting solved it, when disabled the mute button doesn't change colour but does have an effect etc.

This link i.e. http://h10025.www1.hp.com/ewfrf/wc/genericSoftwareDownloadIndex?softwareitem=ob-69039-1&cc=ca&lc=en&... for sp42549.exe (6.10.6140.0 A) worked perfectly for me, so far no high cpu usage. It's lukcy i checked task manager otherwise i wouldn't have noticed it because this machine is much quicker than my old, especially as it's new.

Thanks for the help

Spoke too soon. It's back. Disabled in msconfig, but after a windows update it was enabled again?

Interesting how a Windows Update reverted the offending file. I used System Restore and located the point where HP Health Check did a number on me updating the IDT sound. Still works great after all these days!

Apologies if I'm misinterpreting your comments, but you shouldn't have to disable anything in msconfig once you've installed SP42549. Disabling "Audio Service" was just a temporary workaround prior to the discovery of SP42549. You would only need to disable Audio Service if you were still experiencing high CPU after installing SP42549.

Although I personally haven't experienced this, your audio driver could be updated to a new version by WIndows Update and/or HP Health Check at some point. If SP42549 seems to work for you just keep a copy handy in case you need to re-install it at some point.

Spot on, I installed SP42549.exe and everything was working fine it was running but not using 50%. Then the next day i noticed the issue had come back again- it was using 50% processor (with SP42549 installed). I even tried reinstalling it and it still didn't work so i had to use msconfig to disable it from starting up at boot otherwise i would need to keep killing it manually each time.

Interestingly it re-enabled itself, i had just carried out a windows update so i assume- cannot say for certain- that this enabled it? Unless it done it on it's own but I've rebooted before and it hasn't. Not sure, something strange is going on somewhere.

I have now disabled Comodo's defense+ properly: Main CP>Defense+>Advanced>Defense+ settings>Deactivate Permanently following a comment i've just seen in this thread and currently it seems to have done the trick, but like SP42549.exe it may not have permanently. Will see how it goes.

If it continues and still re-enables itself i'll try writing a batch script to run at startup as also suggested.
