This did not work, all I could hear was silence, with clicking at 1
second intervals. The clicking stopped after opening and closing
mplayer a few times, but that's another issue.
I've got a pdf and a small text file of product info (which I can't
find any URLs for), which both say mono audio for analogue, also in
Windows, Mono audio is the only available option, so I think stereo is
not supported.
Dmesg output attached, it's not loading mts firmware this time.
