Realtek HDMI+NVIDIA vc=No Sound

[irelavv]

Hi to all.

A lot of people have this problem and I've read everything in tihs forum regarding it (in other forums too) but I still can't get it fixed.
When I connect my HDMI with the TV I get picture but no sound.Here's what I've tried so far :
-Installing lates Realtek 2.51 and NVIDIA 258.96 drivers (other device's drivers are also latest)
-Changed the SPDIF cable backwards (Somewhere that helped because the guy had it connected in the worng way)
-Both the playback and comm dev are set to HDMI :




-Recently I've noticed something that is new in NVCP-the sound was and still is enabled through HDMI in the Resolutions menu :



-Installed win7codecs,tried with VLC but still nothing

Any help would be apperciated and thanks in advance.

irelavv, welcome to the forums.

Would help to know which Nvidia card you have (full system specs would help as well) as most of them until recently do not have audio buit into them, and require a 2 pin SPDIF cable connected between the video card and sound card to be able pass audio over HDMI.

Hi stormy.

My specs are : 9500GT video card,Jetway BI-100 motherboard intel bearlake P35 chipset,2GB RAM with 2,5 GHz Penitum Dual Core processor.I've been told that indeed this card doesn't support audio and that's why I'm currently using the SPDIF cable but I already told you I tried connecting it differently because I don't really know is there a difference in which end should be connected to the sc and which to the vc,anyhow I've tried both ways and still no luck.

Just had a quick look at the manual for your motherboard, nice of them to name that header HDMI-SPDIF-out, eliminates any confusion as to what it is for.

As for the cable from the motherboard to the video card, it doesn't matter which end goes where. It is possible though that you have one end on backwards; 1-2 instead of 2-1.

Also does your video card have a HDMI port, or are you using a DVI-HDMI adapter? If using an adapter did it come with the card or one you picked up? Most DVI-HDMI adapters won't work for passing audio as they are not pinned correctly for it.

One more. If it is using an adapter and assuming the card has two DVI ports, have you tried it on both DVI ports, as I believe only one of them is configured on the card to allow audio.

Thanks for the quick reply but the card I'm using has the HDMI port.I've never used adapters but obviously everything is set as it should be.Never before has this problem been bugging me so much.Maybe I've spent more than 3 days staring at the google search results and tried every single thing...One thing was little confusing - there was link that got me to a forum where one guy said that he tried a 185 driver of NVIDIA for Win7 and it worked (I'm not sure if it was on your forums but it doesn't matter because I've tried old drivers both for the sound and video card and I just wasted my time)...
So now I'm stuck with the latest drivers but if you or anybody else has some suggestins about the drivers or the settings or ANYTHING else I'm opened to them.
Thanks in advance

Don't have anything with Realtek audio here but if you haven't ,have a good look through the Realtek control panel for a SPDIF passthrough option.

 

[irelavv]

Nope I've checked there a thousand times but it has just regular options like the playback devices.However,I've enabled and disabled some of the options which were there as well as to the SPDIF input but it doesn't matter what I change because both ways it still doesn't work.

Chanegd the video to 195.39 as amzo suggested in http://www.sevenforums.com/sound-audio/33398-no-sound-hdmi-device-nvidia-realtek-hd-audio-4.html
Uninstaled that goddamn Realtek driver and windows did the job for me...I said what the heck it won't hurt to try the driver that the system installs before I try the R 2.35 dr. and finally I heard music and sounds through the TV
Here's what you'll need to do if the machine doesn't install the drivers - the version and date are most important here so thanks for the help and may others solve this problem sooner

Thanks for letting us know you got it sorted

 

[irelavv]

oh well it was nice while it lasted...
sorry guys but apparently this solution wasn't good enough and the PC decided to make my life hard again...
when I turned off the computer and powered it back on WITHOUT changing my last settings with which my audio worked over HDMI the computer just started playing the video like I didn't make any changes.Now I have to start all over again with this problem and I hope you can help me out.
-Just letting you know that after I didn't succeed to play audio over hdmi again I'm not with the microsoft audio driver-I reinstalled the realtek one because I couldn't hear the speakers with the other ones...

 

[irelavv]

yo just so you know in nvcp (with clone mode) - change resolution - LGTV I CAN'T change the HDMI Audio Enabled-it always stays on Enabled but when the tv is a prim. display I can change it but even then when I select Audio disabled both screens "blink" 2-3 tiems and I click Yes for confirmation but then I see it's not on disabled-it ALWAYS stays on enabled....when I played with the options I though you may find this interesting!

soo ANY help would be appreciated!

HDMI from laptop to Yamaha amp - audio only works if lcd is disconnect

Here's the lowdown :-

Acer Aspire 5935G running a HDMI cable straight to Yamaha RX-V367 amp's HDMI1 input. From there I have the yamaha's HDMI output running to a Samsung LCD (DVI input only, so I use a hdmi to DVI cable for that). I run a dual monitor configuration; the 15.6-inch lappy's LCD + the Samsung 23" LCD in extended mode with the Samsung being the primary display, laptop the secondary extended display. GPU in the lappy is an NVIDIA GT240M.

Now, the issue is I cannot get both video and audio at the same time. The amp is sending the video signal back out through its HDMI output to my samsung LCD monitor just fine when HDMI1 is selected. But I get no audio to my amp whatsoever. I've checked the amps settings and made sure HDMI passthrough to the TV (in this case, pc monitor) is disabled and that the HDMI stream is strictly to be processed only by the amp, not passed through. So I know that is not the issue.

Now, when i check the NVIDIA control panel the external HDMI device it detects is my Samsung LCD, not the RX-V367. This is why I think I am not hearing any sound as the nvidia GPU thinks I am connected directly to a non audio capable samsung lcd, not an amp.

As a form of troubleshooting, I turned off the Yamaha amp and lappy, pulled out my samsung lcd from the hdmi output of the amp, left the hdmi cable plugged in from the lappy to the amp and turned the amp back on, then restarted the lappy (OS is Windows 7 Ultimate 64-bit btw). When I got into Windows the sound was working! - I then took a look in the NVIDIA control panel and it was showing the attached HDMI device as being the RX-V367 - ie. the NVIDIA GPU was now realising it was connecting to a device capable of handling audio and therefore my audio was working. I also noticed another addition in the menu on the left hand side "HDMI audio settings".

But when my samsung display is connected to the amps output, hdmi audio is not possible.


I'm at a total loss. Any ideas why this might be happening?
