XPS 720, No sound
There is no sound on the rear panel of an XPS 720, in addition the speaker icon in right hand corner is marked by a red cross. Selecting it, windows goes through the motions of trying to fix it but it doesn't
Device Manager -> Sound, video and game controllers = shows 7 instances of NVIDIA High Definition Audio. I believe these get installed when graphics card driver is installed - these being two GTX 460 in SLI mode.
I have disabled all of them thinking that the native driver would take over but it made no difference.
The change I made was to fit a cloned SSD of a Win 10 OS from another Dell XPS 720 which has a creative sound card installed.
Any ideas how to proceed, other than reinstalling Win10 again.

Resolved it in case anyone is interested.
Firstly the link to Dell drivers page only seems to be for the Creative sound card, which isn't fitted so no use.
I searched for "High definition audio device driver" which led me to Realtek driver, downloaded, installed, nothing, uninstalled. :Crying:
Next search was "Dell XPS 720 high definition audio driver" that took me to: https://www.driverscape.com/manufacturers/dell/laptops-desktops/dell-xps720/3275
There are 2 listed, second one by Sigmatel is the one installed for working audio.
Happy as I did not need to do Win10 install (again).:Yes:
…. well that's embarrassing, I see the post above refers to the Sigmatel driver :Embarrassed:

What external speakers do you have attached? Check the connections. There is no internal speaker except for system beeps. Attach some speakers to get sound for music and video.

the driver is on your support page, 720 , look there first, get it? first, load it 2nd? oops, its XP old. only.!!!!!
what jack the green one,, and what did you plug in to the 3.5MM round jack whole Green?
the correct answer is.
1: powered amplified external speakers.
2: ear buds
3: or real 3.5mm jacked head phones, and remove first all USB sound devices, ok , or they can have little war.
I think only TRS jack work and not TRRS plugs unless with adaptors. (I say that only based on age , dell books on this PC)
dell only has xp drivers so, why upgrade to 10-32bit.
first find driver, for it but that company (both chips uses) are defunct
so buy uSB to sound dongle new. end the pain of zero chip support sound
and cloning HDD like that is asking for trouble.
all there is , is here (

Thanks for the replies - I posted about 3 hours ago but where has it gone?
I'm back on the old disc (actually 2 configured as RAID 0) and there is sound.
Device manager -> Sound is showing two drivers: 'High Definition Audio Device' and 'NVIDIA High Definition Audio'.
Selecting each of them and getting driver details, it lists 7 files for each. At this point I'm out of my depth - if I copy those files, can I then get Win 10 to install them? If so, how? My gut feeling it is not going to work or be easy.
Anyways, bye for now - I will take a look at the above link for drivers - been busy benchmarking ROTR on different GFX cards.
