DVI-HDMI to LCDTV, ...no audio

i doubt it because, basically i'm already doing that, ..just w/ separate cables.. my HDMI cable goes into the 1st HDMI input on the TV, ...and my PC audio out goes into the PC audio input on the TV (just as the manual states).. the cable there is just combining the two links in the same cable for convenience (less clutter), it's not encoding the audio over HDMI.. i my TV is the problem because it won't accept an alternative audio input (PC audio over the 3.5mm input) when the HDMI input is in use... if i switch the TV input to the other HMDI inputs (that are currently unused), i'll hear the PC audio sound (but of course no video...) - this tells me the TV is automatically shutting out alternative audio input when an HDMI input is connected to a device... of course, i have things hooked up the way the LG manual shows, but do not see the "HDMI-PC" input option, ...just "HDMI1", "HDMI2", "HDMI3", and "RGB-PC" (which uses the alternate PC audio)

i think this is the TV manufactures w/ a lousy support approach to the PC user, ...it's either use your antiquated VGA and PC audio, or use HDMI, ..which has caused more problems than it has solved IMO...

 

Oh , I gotcha .

and you can't find an option to override the audio default in the TV menus .

 

unfortunately not... but this monitor/TV is really growing on me otherwise .. i got a good deal on it (2011 models being liquidated all over), so i think i'll keep it and get a way to make things work...

did a bunch of looking around various avs/computer forums on the web, and it seems like there's a lot of folks w/ this same kinda problem... i think it's the TV manufacturers and their lackadaisical support for the PC market, ...they are all out for HDMI, which was a creation of the movie and entertainment industry, ..and have abandoned DVI (i have older LCDTVs w/ DVI inputs on them)... this is a shame i think because HDMI is constantly evolving (do you have the right "cable" for "deep color", etc.?), and it caters to the HDCP "crowd", which isn't the consumer... DVI is more versatile for video and backwards compatibility because DVI-I handles both digital video and analog VGA in the same connection... HDMI does not... ok me rant over

 

It's too bad your computer doesn't have an hdmi out , life is certainly easier that way

I had a similar issue with my old sattelite receiver that only had a DVI out , and my new tv would not accept the DVI to HDMI conversion cable

 

maybe i should start asking for suggestions on late-model graphics cards w/ HDMI out connection..

i'm not a gamer, so don't need the best/fastest, ..just something budget minded for my 7yr old PC...

 

What about DVI-Component for video to the tv http://www.mycablemart.com/store/cart.php?m=product_detail&p=2861

This should keep the tv audio open to your other audio input

 

that should work, but it would mean giving up digital video, ...since the component pass-through would be analog... DVI/HDMI/DisplayPort is the way to go, ..i'll have to stick to finding something along those lines...

The HDMI-PC doesn't appear on your list of input options because it isn't an actual input - its an input label with a special function.
Press your INPUT button, then hit the blue button (Input Label), scroll down to HDMI1, change its label to HDMI-PC. This should trigger that HDMI port to accept audio over the 1/8" mini audio jack.

 

i tried doing that, ..i assigned the "PC" label to it, which puts a little "PC" wording in the upper right corner or something of the "HDMI1" icon in there (but it doesn't say "HDMI-PC")... so i don't know if that's supposed to force a change in the TV's behavior, but so far it hasn't changed things.. i also upgraded the TV firmware to the latest version downloaded from LG's website, but no change.. i finally put in a email to LG support, to find out what i'm overlooking here,...maybe their user manual has misinformation it it?..

do you have a similar LG tv?

 

No, I have a couple Sony, and a Samsung. But I was taking a cruise through your manual (http://www.lg.com/us/support-product/lg-32LK450) and saw the HDMI-PC thing you saw and noticed it was referred to as a label not an actual input. I thought you may have missed that.
But it's probably safe to say at this point you've been through it all 10x over
The support email is a good idea... Because it sure looks like it's supposed to work the way you want.

I'm curious now.. I should try this on the Sony 40" I have here on the wall beside the PC...hmm

(update)
Well I tried it on this Sony KDL40V5100.. and it is the same problem you have - no sound from the 3.5mm jack except when on the PC SVGA input.
HOWEVER, I just now learned by trying it: The red/white RCA audio-in jacks beside HDMI1 port give me sound on ANY HDMI input that isn't providing its own audio signal - including the one I'm trying this PC on now.
And to me, it wasn't that obvious because they're not clearly labeled or positioned as inputs -they're sorta under the HDMI1 input. See pic.



I know its not your TV.. but maybe try all your RCA audio input jacks to see if yours does the same thing?

 

thanks for the sanity check!

well i just tried the trick you mentioned, ...tried all the RCA inputs, to no avail... on the back of my TV, the HDMI1 and HDMI2 inputs are both "framed" by a label that says "HDMI/DVI", ...which is yet another indication that the TV is supposed to be accepting of this

 

Damn.. Strange indeed. Well lemme know if the support ticket comes through.. I'm outta ideas.

 

Can you take a picture of your TV set's rear inputs?

Lets see!

that should work... but this one has dvi input, which i'd prefer..

..i'm thinking of maybe just getting a new video card w/ an hdmi out.. the newer ones supposedly have an audio codec that will facilitate audio on the hdmi from the card.. i think i can get a decent one for the price of the converters..

 

finally got a response to my inquiry (email) w/ LG.. got a retarded response back telling me that my computer should be configured to output video and audio w/ hdmi... well my question was rather specific about my connections from a DVI port, and the TV is supposed to allow DVI (via DVI to HDMI adapter/cable) and 3.5mm stereo audio in the manual (it is even marked as such on the back panel)!!!!!!!!!! stupid tech support, stupid HDMI

 

Sigh. Sadly, not at all surprising from 1st level tech support.

 

just an FYI/update to anyone curious about getting audio over DVI.....

now that i have newer card (zotac gtx 550ti), i've got two monitors hooked up... primary monitor hdmi-to-dvi (via adapter), and the second one hdmi-hdmi...

..i am able to get audio on the primary monitor, due to the on-board audio codec that gets installed w/ the nvidia driver... so, to summarize, my vid card has two DVI-D, one display port, and two HDMI ports.... primary monitor hooked to one of the DVI-D ports, w/ DVI-HDMI adpater and then HDMI cable to the monitor... the audio is indeed passing from the DVI-D port to the monitor ...
