I have Dolby Surround Sound Speakers on my ACER laptop. Is there a way to get them working with Dolby Advance Audio Virtual Surround Sound? In Windows 7 it works and sounds amazing. how do I get this working in Ubuntu 11.10
Maybe the solution given in this thread can be of help:
Try installing pavucontrol by opening a terminal and typing:
or via Ubuntu Software Center.
After installation, you should be able to configure your audio device with this gui.
Open pavucontrol, go to last tab labeled 'configuration'. From the dropdown-menu, choose your prefered audio module. The choices given there depend on your hardware setup, so I can't tell for sure whether this solves your problem. Just give it a try.
