Question

No sound from laptop to TV with HDMI

by Dec 5, 2012 10:35AM PST

TV: Panasonic Viera TC-L42E50
Laptop 1: Acer Aspire 4810T (Win 7)
Laptop 2: Dell XPS M1330 (Win 7)

I'm trying to connect Laptop 1 to the TV via an HDMI cable. The video transfers no problem but there is no audio.

I've gone into the sound settings and selected the Digital Audio S/PDIF option as 'default'. The computer is sensing sound as the sound bar responds when I play something with audio on Laptop 1 so something is working, just no audio on the TV.

I can hotswap Laptop 2 onto the HDMI and the TV picks up Video and Audio with no problem so that would seem to rule out the Cable or TV settings as issues.

I've also tried rolling back/updating drivers as well as trying the other HDMI ports on the TV to no avail.

Any advice would be amazing, as this is very frustrating. Thanks in advance.

Hmmm

Hmmm...that doesn't show up. Any idea how I would activate that on my computer?

Would I expect that to pop up when the laptop is connected to the tv? I've tried making the connection then restarting the laptop in hopes it would detect it.

It's usually part of the video card driver.

The laptops I've used just have it. Is there more to this story such as you installed the OS?

The computer was purchased a few years ago with Vista and it came with an upgrade disk to Win 7 which was done immediately.

That explains it.

Head to the maker's web site and install motherboard, video and audio drivers for 7.

Hi PP

I have the same problem with my Acer Aspire on Vista

Please read following steps first. This solves 80% of the problems that can occur. 1. Step Please install the latest driver for your card. Please uninstall the old driver first before you install the latest one (start--> settings--> control panel --> add or remove programs --> remove). Are your chipset drivers up-to-date? You can get the newest drivers on the homepage of your mainboard manufacturer. Please be careful with the installation of the latest driver and do not forget to reboot your PC after finishing.

Good luck
