How do you play an audio only (quadraphonic) DVD? I mounted the DVD to look
around:

root@pc:~# ls -lhR /mnt/temp

I don't know a good method:

eben@pc:/tmp$ mplayer -dvd-device /dev/loop2 -ao alsa dvd://1
MPlayer dev-CVS--4.0.2 (C) 2000-2005 MPlayer Team
...
Playing dvd://1.
Reading disc structure, please wait...
Can't open VMG info!
File not found: '1'
Failed to open dvd://1
...

eben@pc:/tmp$ mplayer -dvd-device /dev/loop2 -ao alsa dvd://
...
Playing dvd://.
Reading disc structure, please wait...
Can't open VMG info!
[file] No filename

...

eben@pc:/tmp$ mplayer -ao alsa /mnt/temp/AUDIO_TS/ATS_01_2.AOB
(tried to interpret ATS_01_2.AOB as a video and got garbage)

eben@pc:/tmp$ mplayer -dvd-device /dev/loop2 -ao alsa dvd://AUDIO_TS/ATS_01_2.AOB
...
Playing dvd://AUDIO_TS/ATS_01_2.AOB.
The hostname option must be an integer: AUDIO_TS
Struct dvd, field hostname parsing error: AUDIO_TS
Option stream url: This URL doesn't have a hostname part.
Reading disc structure, please wait...
Can't open VMG info!
...

So, is there a way to hear this and preserve its 4-channel nature?
