from the sound card. If there isn't one, you will not have sound using that operating system.
I have a Gateway Laptop, M675XL. I just upgraded to Vista Ultimate and now there is not sound. If I go to the speakers properties and then go under the drivers tab, I see that I have SigmaTel C-Major audio. The driver version is 6.14.14175. If I click Driver Details I see four driver files:
C:\Windows\system32\drivers\dmk.sys
C:\windows\system32\drivers\portcls.sys
C:\windows\system32\drivers\STAC97.sys
C:\windows\system32\drivers\stac97co.dll
If I try to "update driver" windows will do a search online, and then tell me that the drivers are up to date.
Neither my computer speakers, nor my external speakers are working at all, and every menu I can find that has to do with sound, shows that everything is unmuted and at full volume and enabled.
Can anyone help me figure out why I have no sound and lead me to a solution? Please write me back and let me know exactly what you will need to help me troubleshoot. thank you in advance!!
