Hello everyone,
I just installed Window 7 today to my Acer 57387 with new hardrive. Everything is working except there is no Sound. The speaker logo has red cross mark and message said " No audio output device is installed" .
Try to installed the audio driver from acer support webside but did not work. Anyone has any idea where to get the audio driver for WD 7?
Thank you in advanced

Try a Realtek driver from http://www.realtek.com/

Also try Microsoft's Fix-it for Audio

If the drivers ARE installed then go to Control Panel \ Sound and make sure speakers are set to be the default
