Windows 10: Nvidia Graphics card and HDMI port says "cable Not plugged in"

I plugged my laptop into an integra 30.4 receiver via HDMI port (multiple ports) and with the receiver on the right device port and connected to a tv or a projector and I get no audio out of the HDMI port only Video. Video works great!

The laptop is an alienware laptop on Windows 10 (upgraded from windows 7 purchased November of 2011). The HDMI would transfer audio and video in windows 7 intermittently for a year or two. However, I had to turn the tv, receiver, and computer on in a specific order and eventually, approximately 1 hour of doing this each time I wanted audio I'd get the audio over the HDMI cable until I shut down....

I've been on windows 10 now for a while and never have gotten the HDMI audio to work. I kinda gave up but would like to use my laptop now to play movies to my new epson 4k projector and am unable to get audio to work at all. Video is phenomenal.

The HDMI port shows up in the device manager under sound devices. However, constantly shows "Cable not plugged in" whether the cable is or is not plugged in.

It's an older Geforce card - wanna say it's a Geforce 555. Also has an intel graphics adapter as well. I've done all the nvidia updates, windows updates, I've gone so far as removing the sound adapters and rebooting, removing the graphics adapters and letting them reinstall. The HDMI audio port always comes back with "Cable Not plugged in." It's staring me in the face constantly.

I kinda gave up and switched to broadcasting using Chromecast which works o.k. but it's streaming it over chrome on my home network and I feel a direct connect via HDMI would have less buffering and less latency and best quality audio / video.

Any suggestions?

Yes, 1 HDMI on the motherboard, 1 VGA on the motherboard, 1 Mini HDMI on my graphics card, and 1 DVI-D port on my graphics card.

 

Windows 10 cannot detect my TV as a second monitor! (SOLVED!)

Hi,

There is one.... And I was using that one....... dang!! lol



Honestly, I didn't knew there is another hdmi port at the bottom where the graphic card is, I thought the PC has only one hdmi port (just as my laptop), It's a new PC, bought it few days ago and had no time to examine it in full. So, I saw the upper one hdmi
port and just plugged the cable in it... Didn't noticed the second hdmi port when plugging in the main monitor.

Oh my.... So much time wasted for something that simple... I should have asked here earlier!! lol

Plugged the hdmi cable in the lower port (between the DVI and VGA) and the second display became visible instantly!





Thank you very much Richard!! Thank you sir!

Cheers!

 

Wrong version HDMI Cable perhaps ? faulty HDMI cable ? faulty HDMI port ? bent pins ?

Or some incompatibility with the receiver ?

I am no expert on this , just guesses having seen other post similar experiences.....
