Dell Inspiron SigmaTel C-Major Audio won't continue to work

I have a very weird problem with my Dell Inspiron 8600. The sound works off and on. I can't figure out exactly how to make it work consistantly. Different things make it work. I had thought it was related to how long the computer was on but that doesn't seem to be the case. I tried turning off other devices and it didn't help. I just don't know what else to try. I have tried everything I can think of. Any suggestions would be very appreciated. I have also had this system looked at by several other people and they haven't been able to figure it out either. no sound at all all drivers upto date bios ok default audio enabled to sigmatel c major everything configured to work but still no sound

If after reinstalling the operating system and the sound drivers you get the same problem then your sound chip is faulty,

dont know if there is a pcmci sound card but if there is, that would be your solution or else consider swapping the board

I have a problem with my Inspiron 1150. Just a couple of weeks ago the sound all of sudden stopped working. I have tried to reinstall the SigmaTel driver but it won't let me. An error message comes up...

Your laptop has a hardware problem. The unrecognized sound card and USB ports are a dead giveaway. You probably have a loose wire, or worse, a motherboard that is going bad. If your laptop is under warranty, call Dell and get the laptop to them right away. If not, you'll have to have an experienced repair person look at it and you'll have to decide if it's worth fixing. I'm such a person, and I'm a Dell partner. I'm in Rockville, MD and if you're nearby, please call me or send me a message through my website.

Dell Inspiron SigmaTel C-Major Audio won't continue to work

running windows xp? okay click start and scroll to control panel. under control panel scroll to system icon and click. the system property box will open. click hardware then the device manager tab. clik on the sound, video and game controllers, this will open and you will see a list of installed sound devices/codecs as well as video codecs. see if the sigmatel codec is listed it is possible that it may be present but not set as the default. this can happen when installed programs such as media player, real player,quicktime.. install their own drivers to control the video and audio components. the codec is simply a driver program which interfaces between the computers installed hardware and the computers software, IE real player. I have an inspiron e1505, I ran into a similar situation and lost my sigma tel driver. it had to be reinstalled. PAY CLOSE ATTENTION------------------- GO TO THE DELL COMPUTERS SUPPORT WEBSITE. type dellsupport on web search navigate to the downloads section where it gives you the option of inputing your computer make and model, then select your oprating system. look for the downloads for audio devices, you should be able to find the sigma tel codec available for download. save the file to your hard drive in a location where you can access it again. okay back to correcting the problem on the device manager display under sound, video and game controllers. if you do not see the sigmatel codec then run the download from dell for the sigmatel and it will install automatically. hopefully this will correct your problem, it sounds to me like it is a driver problem the above steps will definately identify the sourcee and should provide solution to your problem
