Solved No sound over HDMI from pc to tv galaxy gf 8800 gt

[meromajd]

Dear users.

I have plugged hdmi cable from pc to tv and picture is fine.
In nvidia control panel there is a setup digital audio option
it detects my vga caed and i can select sound turn off or LG tv.
so there is a bright spot at the end of the tunnel.

In sound/playback only speaker and spdif out appears.
i have checked disabled and disconnected devices.
i connected the mobo with the jumper jp2
is is supposed to be the vga spdif connector according to this picture:

the mobo layout of spdif out is clear so i could not made it wrong.
but as for the vga there is a catch here since i do not know the order of cables on the vga to connect.
and i am not even 100% sure that the jp2 is what i think to be.

i have installed latest mobo sound driver and nvidia driver as well.

i was hoping that the hdmi sound output would appear in the sound/playback but id did not no matter i connected the crossover spdif cable one way or the other.


thats how far i managed to get. Any ideas please?

Ps: sorry for my bad English i am not a native. And this is also my first thread on any forums. Thank you

Go to control panel and then choose sound. When in sound you need to change the default audio from your PC to the TV. When you want to turn it back you do the opposite.

Make sure both show disabled devices and disconnect devices are checked.

if i go to control panel and then to sound only spif interface and speakers appear.
tv only appears in nvidia control panel and i select it and then do apply and then nothing happens.

Try removing the cable and then inserting it again, and when you go into sound see if there is anyway you can search for the HDMI cable.

I had a similar problem and you had to do something to get the tv recognised in sound but I cannot remember what.

If you have headphones plugged in remove them as well.

Your using the HDMI slot in your graphics card, so I would recommend that you disable the device then re-enable it, and also make sure the drivers are up to date.

i also noticed when i plugged out the hdmi cable and when i plugged it in a scratchy sound came from the tv for a very brief moment.

go into the device manager in control panel and try disabling the graphics card and see if the TV appears

i have disabled the vga and then reenabled it. a scratchy sound could be heard at the moment of reenabling but no sound option change. i installed the latest sound drivers some days ago.

You should also try selecting screen resolution by right clicking on the desktop, have it so that desktop is extended across both displays.

If you are using a HDMI cable then there is no need to use a VGA cable. Unplug your VGA cable and then try to see if the sound works, and see if the TV appears in the sound options.

 

[BomberAF]

With a VGA cable you cannot get sound you need to use an audio jack cable like the one you use from your PC to your monitor.

 

[BomberAF]

If you are using one of these then you can't get sound:-

unless you use one of these

i plugged out the dvi and then did a pc restart with only the hdmi connecting tv.
sratchy sound at the login screen. and no change in the playback/sound.

So now the HDMI cable is the only cable connected to the TV, have you checked again in the sound options, and have you tried extending the screen to appear over both the computer monitor and the TV. When you have extended them check the sound options again.

 

[BomberAF]

If you where using a DVI cable in order to get sound through that cable then you should go to the PC option on your TV.

Right now i only have the hdmi cable connecting the pc and the tv. so i cannot extend. but i tried to extend it before so the pc was connected with the monitor via a DVI cable, and the pc was also connected with the tv via the HDMI cable. and still nothing happened.

You can extend the display so that it appears over both displays, right click on the desktop and choose screen resolution.
