Having problems with your Acer 90.00012.30B Computer Speakers ?

Very bad echo, on my NEW Acer laptop 8730G-6945


Answers :

I had this problem for months - I finally figured it out on my own...

Go to your RealTek HD Audio Manager (this is either a red speaker icon in the bottom right hand corner or if you go to 'control panel, sounds speak and audio devices, realtek hd sound effect manager)

once you have the window open, under 'sound effect, go to environment and to the right of the drop down menu, click 'RESET'.

After months of trying to fix this issue, this fixed it for me!!! I hope it does for you too!
I had the same problem. I totally fixed it, finally! I went to control panel, then sound, then recording, then I right clicked on microphone and selected properties then clicked on enhancements and I checked "disable all sound effects" box then hit ok and ok again. And BINGO! No more echo.
