Any HDMI experts on the Forum?

Steve, I'll power down later and pull the graphics card, but at the moment there is nowhere for the GTX 660 to play audio even if it has an input jack. I'll do a bit more physical investigation after super.

(This card is really intended for gaming, but I'm using it for 3D scanning using an Xbox 360 Kinetic sensor amongst other things like Fusion 360.)

Hi Andrew

if you can not get the onboard audio working for some reason

try looking for an inexpensive HDMI audio adaptor

Well it's all very odd  :scratch:

Steve, no sign of any audio connectors on this humongous card. Other than the 6 pin auxiliary power input connector giving a meaty 12 v supply and the PCi-E slot there are no connectors other than those on the rear  (2 x DVI , 1 x HDMI and 1 x Displayport). The thick paper 'manual' has a single page of English of no relevance essentially just saying plug it in ! The manual on CD has 331 pages and the words 'sound' and 'audio' don't occur at all  :bang:

John, that sounds a good approach, but my understanding is that the audio is digitally encoded on an HDMI connection - googling "HDMI audio adaptor" I come up with what seem to be just cable adaptors, but presumably the 'far end' needs some intelligence to convert back to  analogue audio  :scratch:

The internal speaker features in the list of devices under Device Manager, and under 'properties' says no drivers are loaded, however if I go into the driver part it says that the device is working properly. If I tell it to update the drivers it says that I have the latest ones  :bang: The on board audio device says it's working and has the latest drivers. If I disable the Nvidia audio devices then 'Audio Manager' says that there are no audio devices - I was expecting the on board one to spring into life  :scratch:

Why is life so complicated  :med:

John Swift:
Hi Andrew

a search for HDMI headphone adaptor

my first result was this from amazon

https://www.amazon.co.uk/Adapter-Upgraded-VicTsing-Gold-Plated-Converter/dp/B016I34422/ref=sr_1_1?ie=UTF8&qid=1498505426&sr=8-1&keywords=hdmi+to+headphone

it gives you both audio and VGA outputs for £6.59

Win10 generic drivers don't work well with some devices.

I'd check for Win10 drivers from either download site for the Motherboard, or from the web site of the audio device manufacturer.
