The sound is great as always, but there are a couple of issues that I'm looking to find solutions to: - After setting my volume to 100:100 using mixer the real volume is only 1/5th or 1/6th of what it should be. This is might be due to a lack of support for the Revo's volume control chipset, but I don't have any experience writing sound drivers so I'm not sure. - Only one output channel (stereo) is used. I do not have access to the rear speakers in a 5.1 setup. sndstat output: http://dpaste.com/112401/ mixer output: http://dpaste.com/112402/ In /dev, dsp0.0, mixer0 and sndstat are the only sound devices. Let me know if you have any suggestions, thanks! -- Charlie La Mothe
