One additional point: Be sure you're using the correct device type (Analog V4L 
Capture Card, MPEG-2 Encoder Card, etc.).  Not all devices require 
configuring a separate audio device. In particular, the MPEG-2 cards (such as 
the popular Hauppauge PVR-x50/PVR-500 line) send audio in the MPEG-2 stream 
along with the video. The most popular card type that needs a separate audio 
device is a framegrabber (aka software encoder), identified in mythtv-setup 
as Analog V4L Capture Card.
