What soundcard does the M4500 have?

Hi all,

Just need confirmation of what soundcard the M4500 has?

Rebuilt machine, didnt bother checking...
Dell drivers is the IDT HD 92xx driver but I'm having issues where I am not getting sound properly.

For instance, I have Chrome open, sound is meant to be playing but its not.
Clicking on the Volume symbol does indeed show the volume going up/down and what is interesting is that it is showing the sound working under the headphone symbol.

From what I can make out, the machine thinks the sound is coming out via a headphone. I do however get other sounds such as MP3 or system sounds from the speaker.

 

Does a headphone work? If so, it's likely a stuck headphone jack. This type of problem is more common on mobile phones as the 2.5mm jacks are more delicate.

 

Thanks for the reply - Yup the headphone jack works fine. I actually repair phones so I knew about the jack issue but def isnt that.
What is interesting is the "faulty" M4500 I got previously had the same issue.

I rolled back the driver this morning to the stock W7 driver and everythings working fine now. So it is a driver related issue.

It would be good if someone could confirm what they had so I could check...on googling, I noticed people fixed their sound issues by using a Sigma driver and not the IDT driver - IDT seems to have taken over Sigma?

 

If you uninstalled the driver, does Windows Update try to push a driver?
