We ran an HDMI cable from the laptop to the TV, get video but no audio. The TV will receive audio from Wii and Dish and an old DVD player but not from the computer.
The computer produces sounds via its own speaker and will send audio to an old CD player.
What more information do I need to ask an intelligent question as to why I cannot send sound via HDMI cable from the laptop to the TV?
Is Windows configured to use the HDMI port as the audio output device? Check the Sound control panel. Need to know what version of Windows you are running to give more details.
I have this problem with my PS3. It’s because my LG TV doesn’t accept audio via HDMI. There’s no way round it: I have to pipe the audio into my multimedia speakers separately.
Sometimes the HDMI port does not support audio out because of your sound card
Cable is a Philips HDMI 4x 1080+, 6ft. no wall plate.
Laptop is an HP with Windows 7.x upgraded to the latest according to Microsoft.
The laptop card is a NVIDIDA upgraded to the latest according to Microsoft. [Here it get a bit more confusing. NVIDIDA said there was a later upgrade but it will not work. The whole PC freezes. Have to uninstall and return to the latest according to MS.]
We have tried to pass analog sound from the laptop to the TV. This will not work. [We can pass analog sound from the laptop to an old CD player while passing HD vidio to the TV.]
The TV is a Magnavox 32MF23ID LCD TV. We found one software upgrade (32MF23ID/37)for that and it was installed.
I had an old HDTV like that - does the HDMI input have a couple RCA audio inputs next to it like mine did? The PS3 can be set up to output HDMI video and analog sound.
Try opening your computer’s Control Panel, then click on Sound. You should have a small window open for setting your sound options. On the Playback tab you will hopefully see something like NVIDEA HDMI Output (I am guessing here cos mine is ATI not NVIDIA). Assuming it is plugged in you can click on that device and use the Set Default setting below. This worked for me.
Does the NVidia card require a pass through cable to output HDMI audio? (I know my 9600GT requires this since it has no built in sound. Unfortunately it wants spdif and my motherboard does HD-Audio so I’d have to do some hacks to get sound out of the HDMI port.)
Confused. Your laptop has an honest-to-god HDMI Out port? Or are you using an adapter from a DVI port? It would help if you give the model name and number of the laptop and the card.
It is somewhat likely that your laptop does not support audio over hdmi, again we really need to know the exact model number of it to give you an answer though.
With my laptop (toshiba) sometimes the audio will switch from speakers to HDMI automatically and sometimes it won’t. I’m not sure if it’s triggered by plugging in the cable, and if so, if it matters if the TV or laptop are on/off. If it doesn’t work, I just go to control panel as described above, select HDMI out, and click “set as default.”
I’ve also noticed that if I already have a browser window open to watch something (I am ususally using the laptop to watch shows or Netflix), I have to close and reload the browser for the sound to finally work.
Aside: Another strange effect is that if I turn the TV off with the HDMI cable still connected to the computer, it will shut the computer off too. Weird.
Right click the little speaker icon by the clock to get a menu, then click Playback Devices. Another way to get to the same place is Control Panel, Sound, Playback tab.
Now click Digital Audio (S/PDIF) then click Set Default.
I’m not familiar with the HP laptops as much, so if there is not a "Digital Audio (S/PDIF) but there is something in the list besides Speakers and Headphones, it’s probably the Digital Audio you’re looking for.
If it doesn’t switch back to speakers or headphones automatically when you’re done with HDMI, you can use the above steps to set your default back. If your laptop just won’t do audio over HDMI, then you have to plug into the headset port and run that into your stereo’s TV or Aux inputs.
