hdmi sound - none when connecting to my Toshiba TV

arnieboy · January 2017

Hi, I have read numerous threads on my issue. Although I can't prove it 100%, since getting Windows 10, my tv has no sound when playing from my laptop via the HDMI cable. I have tried:

1. Updating drivers.

2. Right clicking the speaker icon in the system tray and changing everything I can think of. This includes ensuring playback devices has the tick for showing disabled devices, for which I see none. I only see Realtek high def audio.

3. Uninstalling the hd audio, rebooting, reinstalling and rebooting.

4. Trying numerous hdmi cables in different hdmi sockets on the TV.

5. Trying another laptop on the same tv and seeing if the tv has a setting to change (it does not).

6. Changing recording devices settings.

7. Looking for any drivers on the acer website.

All I want is sound to play please. Any help appreciated. I have an E1-532 laptop. Thanks.

Audio via HDMI is managed by graphic drivers, so you need to check Intel drivers and update them if available.

i can suggest you to download Intel software updater:

http://www.intel.com/content/www/us/en/support/detect.html

check if it find any graphic drivers update and download it, then you need to first block windows automatic drivers update:

Intel software will advise you that a custom driver is installed, so you need first to uninstall Acer/Intel drivers:

windows logo key + x

click on Device manager

click on Display adapters

right click on Intel graphic adapter

choose to uninstall and tick to uninstall software too

once done, you can try to install downloaded Intel drivers or reboot if asked and then install the downloaded drivers.

Thanks for the suggestion. The Intel utility says "no drivers were detected for your product". Therefore, I did not go to the second link you posted.

Any ideas please?

Hi, my laptop shows it is Windows 10 home, 64 bit operating system, x64 based processor. Therefore I downloaded https://downloadcenter.intel.com/download/25977/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-33-?product=97499

However, this says the computer does not meet the minimum requirements for installing the software. The device manager shows "Intel HD graphics" under display adapters. I tried other links and got various messages but all along the lines of nothing to install or won't install.

Any more ideas please? Thanks again....
