You are making progress! The 5.1 setting is broken so that has to be
set to stereo and, as the documentation says, you still get 5.1 even
though it says stereo.
You are getting noise out. I assume this is digital noise going out the
analog output. When that happened to me, it was because I had the
output setting to digital. If you are in fact trying to get analog
audio out, you should set myth to ALSA:default and make sure that ALSA
is not set up for a digital output as the default. Like I said, the
easiest way to do that is to remove the config files.
