Acer Aspire Sound Problems After Win 7 Pro and new HDD Install

I have an acer aspire 8735g-6502 laptop that recently suffered a WD 500 gb HDD failure. I replaced this with a Hitachi 1TB 7200 drive and since I did not have an original Win 7 home used a Win 7 Pro disk that a friend had extra.

The HDD and Win 7 Pro install went smooth. But, now when I plug an HDMI cable in to watch through my Marantz Receiver, the video comes through, but, I have to manually make the Marantz the default sound device to get sound. When I unplug the HDMI, I have to go back into sound settings and unenable the Marantz and re-enable the Realtek audio.

Before the HDD died, this would all happen seamlessly when plugging the HDMI cable in and unplugging without any fiddling around with settings.

I also have a couple other issues:
1. The touch volume control next to the number pad does not control the volume anymore
2. The keyboard pad used to have a display adjustment to it. You could use two fingers like on a tablet to drag the screen image bigger and smaller.

I looked at the Acer site and also used my Application and Drivers disk to reinstall everything that looked related to these issues. When i first installed Win 7 Pro I just let Windows find the appropriate drivers. That worked for some things but not others.

Any ideas? I have a few scratches on my face and my forehead hurts from frustration causing me to beat myself up here. :)  Funny, but true, so any ideas are appreciated!!!

 

Here is my Devise Mgr screen print - there is one "unknown" device that IDK how to figure out what it is.

    hi...

     

    Have you installed the launch mnager application. If not you may install it from this weblink and check the touch volume control function and display adjustment  Launch manager application

    I would love to understand how this solution worked. It definitely solved the screen size issue and volume adjustment problem. I will check the other issue with transferring the volume to the HDMI port when plugged in and transferring volume back to the computer when I unplug the HDMI cable.

     

    A Bg Thanks!

    Volume control now transfers between devices when plugging and unplugging into the HDMI port. That may have been the result of changing a setting in Manage Audio Devices>Communications>Mute all other sounds to ON.

     

    Thanks again Sharanji!
