This seems to work very well for me on my bedroom frontend. Thank you to everyone involved. I want to add that I had to change my "Mixer Control" setting to "Master" in order for this to work properly. I had no control over the volume until I made this change. I had the "Master Mixer Volume" slider set to 95% when I first tried it and I nearly gave my wife a heart attack and woke up the kids because the volume was so loud. This setting is great for those shows where it seems like half the dialogue is mumbled (i.e. "The Office"). Here are my settings in R5.5 in case anyone wants to know: /etc/asound.conf was copied and pasted from page 1 of this thread. I'm using analogue audio out of my soundcard which feeds a cheap pair of powered speakers. Quote: Audio Output device: ALSA:ladcomp
