Hi all,

I have an Acer Aspire V3-551G-X419 w/ AMD Radeon HD 7660G + 7670M cards.

I recently went to update my drivers and this required installing Catalyst Control Center which I didn't have previously. Everything installed fine and upon rebooting I realized that the HDMI sound option had completely disappearsed. Going into my device manager, I see that the HDMI option is only viewable under Show Hidden Devices and clicking on it says that the hardware device is not connected (which is not true, since the video displays just fine). Cataylst doesn't seem to have any options for audio.

I've tried uninstalling the new drivers and while this brings back the HDMI sound option, it causes display problems, notably: I cannot start steam or watch videos from my desktop. From this point, I also tried installing the VGA drivers from Acer's site, but this presented the same problems, sounds but display issues. I also tried installing the audio drivers from Acer's website with the new display drivers installed but no luck with that either.

I'm out of ideas of what could be causing this. Could anybody please help me out?

I am having the exact same problem with my Acer Aspire e1-451g with windows 8 64-bit, amd a8-4500m processor with built-in Radeon HD 7640G and a dedicated 2gb radeon hd 8750m. I had an older version of catalyst and display drivers and then decided to try and update to version 14.4 of catalyst and 14.1 of the amd display driver. when i install these things, my hdmi audio is no longer on my playback devices list and is also seen as disconnected under the Device Manager. All I can do is uninstall the driver everytime i want to watch something on my tv through hdmi. its getting really annoying, ive tried uninstalling all audio drivers and reinstalling, ive tried installing the catalyst 14.4 package with and without the amd hdmi audio driver, to no avail. ideally i'd like to have the latest driver AND my hdmi sound back. i did notice that as i was installing the package, all of a sudden i had two amd high definition audio devices under my Playback devices, then when i restart again, completely gone. can anyone shed some light on this problem!?
