Mostly useful for people who don't have/use a receiver/amp. Most
likely, the quality of the D/A in the soundcard is significantly (and
noticeably--for people with better ears than me) lower quality than that
in receivers/amps, so the analog output is unlikely to have any benefits
(other than the "don't need new equipment" one mentioned--yours (new
meaning recent) and mine (new meaning additional)).
Steven Adeff wrote a lot of good info--and changed my opinion on the
benefits of digital output--in the thread at
http://www.gossamer-threads.com/lists/mythtv/users/200580#200580 . I'm
still waiting for my 8-channel PCM output using DisplayPort (now more
desirable than HDMI 1.3+, which I had previously wanted--but I don't
think either is available, yet).
