| This handles the audio drivers and services for yout Sigmatel compatible sound card and 5.1 software surround, its authentic and official, dont uninstall as you will lose the advanced features if your sound card. Kirk R | |
| I wondered today why my system is hot like hell and discoverd that the process stacsv.exe gathered 50% performance of my dualcore cpu. I kicked the process and my system still works fine Davion | |
| I have had problems with it. Causes one core of my dual core laptop to constantly run at 100% making CPU usage at 50% overall Ray | |
| it was a virus on my keychain drive. created it's own autorun.ini saying to run it. Daryl | |
| I find that when it runs, it uses 50% of my CPU and so I stop it. Audio etc still works, I think it may be used to sense when headphones or mics are plugged in Ray | |
| It's function is to automatically identify if there's a set of headphones connected. So it's not essential.. | |
| legit process but goes on high CPU usage for no reason Stephane | |
| In my HP Pavilion dv5 1070-ew stopping this service prevent the mute icon to change it's color (but it will still work as it supposed to, it just always stays red). When the service is disabled, then volume slider behaviour seems to be bugged, but IDK if it was the reason. I keep that service running, however it's not essential for audio and audio buttons work. Faalagorn | |
| I got the same message "STacSV Module stopped working and was closed" after waking up my HP Pavilion HDX9490eo from hibernatition but I could nevertheless listen to streaming music from the Web. So it doesn't seem critical for audio, at least on my machine. Windows advice was to go to the manufacturer's web site and upgrade the drivers. This has happened to me once before but since it obviously didn't affect my audio listening, I really didn't care about it. Those user who think its harmful must be wrong about that Bengt Sundvall, Sweden | |
| STacSV: Manages audio jack configurations edizzi | |
| This is an installed audio device driver for SigmaTel STAC-based audio devices. It is essential for the functioning of audio playback and recording on systems with STAC-based audio devices. Fake Al Gore | |
| i am using Dell XPS studio 1340 laptop In my system this file using 50% processor resources i know it is essential because it is related to audio in system but i think there might be a chance virus can corrupt it otherwise why this file need 50% processor resources? Aravind kumar | |
| SigmaTel Audio Service is stacsv and it locates on program files. If the file name is STacSV and it is located on System32, it is a VIRUS! Nick | |
| Sigmatel Audio Driver - but wht is mine trying to broadcast to the network? Bill | |
| i turned it off cos its used 50% of my cpu and my speakers and headphones still both work perfectly i just wish i could fine a way to stop it coming on rather than having to terminate it from the task manager Tom | |
| Its using 50% of my resources on windows 7 DennisG | |
| It's an audio driver, sometimes it stucks and load a lot CPU, in my case, after upgrading visto to windows 7. Ih you want to avoid CPU load click start- run- type services.msc- find service called "audio driver" click properties stop it and mark Startup as Disabled. That should not disable audio in windows just stops audio software. Jemalas | |
| it's littlebit dangerous. basicly it is attacking of your all exe files and only way you have to delete the exe files. | |
| sometimes, it is a malware with rootkit. See also: Link Kevin Hwang, in Korea | |

| Legitimate audio component included with Dell laptops See also: Link EJ Smith | |
| For me it takes up 100% use of one of my two cores. I often just end the process which makes the sound a little off but it still works. MeorI | |
| Caused by a bad Sigmatel driver version 5.10.4821.0, can cause no audio from Win Media Encoder recordings Jeff S | |
| eehm,security task manager said this process is giving 99% CPU. now it's always 100 CPU.... what to do? Erwin | |
| It is resource hungry, keeps processor hot so fan runs contantly on full power. | |
| Yes it is for sound card. Update your drivers if it is giving you issues. | |
| when i get the "STacSV Module has stopped working" message, my speakers no longer mute when i plug in headphones. i get sound in my headphones and over the speakers will thomas | |
| If it's not a virus masquerading as the original, it can be the driver for several audio cards. If it is taking 50% of your CPU, AND you are not playing games or listening to music AND you have the DEFAULT driver for all the MS Window sounds, you probably have a virus. Before panicking, be sure you are not using your audio - just muting it is not the same as not using it. TJ Fox | |
| Here the error message appears immediately after network login, so before loading the Windows icons and taskbar. EJ Smith, I donīt use Dell Kees | |
| it's using all my cpu. im not a techy i just want to smash my laptop when this happens | |
| it caused an expection / bluescreen on my HP ProBook 650b during startup , I deinstalled the sounddrivers, now the system crashed somewhere else ... I can not blame STacSV.exe for being the problem. Gerd K. | |
| it is an audio application and can be ended, It used a lot of CPU of startup. Trevor | |
| It's nothing but a audio drvier,not dangerous at all Pr | |
| It is an annoying error and virus! It comes with ITM or Sigmatel Audio, just uninstall it! Skills | |
| My one was located in Program Files, i searched it and it says it was a virus, so i disabled it | |
| Service Name: Audio Service Service description: Manages audio jack configurations. Executed file: C:\Program Files\IDT\WDM\STacSV.exe MyNote: really stupid service. Produce huge loading on computer. Alexey K | |
| This application can conflict with other audio drivers for your hardware. If you receive Windows Event Log Errors with code 65535, then you should uninstall it. JK Benedict | |
