since my acer aspire 6935g had been upgraded from vista to wondows 7 the dolby home theater (virtual surroungdSwoud) went lost.
please help for get it back. thanks a lot. Hans D.
Does not look like that system has Audio drivers from Acer for 7. Try doing a Windows Update and see if it picks up newer drivers. Can also try the Vista audio drivers and install in Vista Compatibility mode.
