Windows 7: Having problems with hdmi audio

11 Feb 2011   #11

Windows 7 Home Edition


I've been having similar issues over the last few days with getting HDMI output to appear. Here's what I did which worked today, hope this helps:

- Go to Control Panel
- Choose 'System'
- Click 'Device Manager' near the top left
- Right click on "Sound, video and game controllers"
- Choose 'Scan for hardware changes'.

And it appeared...

I did this right after I'd installed the latest ATI drivers for my laptop.

Anyway good luck.

Edit: Oh, and when it appears in the playback devices, click on that and select as default

Any solution?

I have the same problem with a simular notebook and same graphic card. Have tried installing different drivers as well with no luck. I would be very interested to hear any solution you might have found for this problem

The only solution i have found working is turning the graphic to descret in the BIOS. Have you found any other solution?

Windows 7 Home Premium 32bit
Fixed - use the Vista 32 bit driver 06-02-2009

I had the same problem you're describing, EXACTLY, no HDMI audio output for my Acer Timeline 5810TZ but video output worked great.

Running Windows 7 Home 32 bit upgrade from Vista. Same thing, I could see the HDMI in the BIOS but it didn't show up in the Playback properties, even with "show hidden devices" selected.

So I went to the Acer website for downloads and selected Windows Vista 32-bit for the Operating System. Scrolled down to the Realtek audio driver, selected the 06-02-2009 version for Vista, and downloaded it.

I then went into the Control Panel and uninstalled BOTH the HDMI audio driver AND the regular audio driver, checking the box to uninstall the software. I did NOT reboot.

I then opened the new Realtek Vista driver and ran it, let it finish installing, then rebooted my computer. It booted back up, and Voila! Speaker sound, SPDIF digital output, AND... wait for it... HDMI output, all show up under playback devices.

Plugged in my HDMI cable, put it in sleep mode, brought it back out and put a video on, outputs both video AND audio, no problem, works great!

Best of luck to you...
