The install did take a few attempts to work - weird things happened with Vista trying to re-install drivers (old or new I don't know), and the install program hung on at least one occasion. Can't remember where I got the drivers, but they are on the realtek site (didn't use that site though as it's so slow).

I uninstalled my existing drivers, and ran the realtek install program in XP SP2 compatibility as administrator. What finally worked for my Sigmatel C-Major was the Realtek AC'97 XP drivers (I've read bad things about their Vista beta drivers). I've got the Dell Inspiron 6000 laptop, and tried everything above, numerous times and for all variations, but to no avail (no sound through the headphone). STAC97.cpl = SigmaTel = 1.0.0.12 (this control panel item now causes a registry key error)

However Windows Update provided a driver called 'SigmaTel C-Major Audio', which has a newer version than the Dell XP one.Īlthough, using the Windows Update driver is fine with the onboard laptop speakers (Latitude D610), but no output is possible through the headphone jack (it reports that it is mono, but is stereo and works fine under XP).ĭoes anyone know how to resolve this output issue? (Note : The XP driver causes it to report no jack information)

When I installed Vista Beta 2, and Beta Build 5456, both times Vista failed to find the audio driver automatically during installation. The driver mentioned above is just the Windows XP driver provided by Dell, which can be installed on Vista.
