Ok, my mistake for copy-paste from an ssh terminal.

I've recompiled mplayer from snapshot (cvs is down), added some printfs in
dec_audio.c, and got the following:

mplayer cdda://1 -ac ffdts

Try adding "echo 1024 > /proc/sys/dev/rtc/max-user-freq" to your system
startup scripts.

Playing cdda://1.
Found audio CD with 7 tracks.

Track 1
==========================================================================
check 1
check 2
check 4
Forced audio codec: ffdts
init_audio start
init_audio: inside     while(1){
init_audio: didn't break
init_audio:     // ok we found one codec
init_audio: codec name is pcm
init_audio: inside     while(1){
init_audio: computer says no
check 8
Cannot find codec for audio format 0x1.
Read DOCS/HTML/en/codecs.html!
==========================================================================
Audio: no sound
Video: no video


Exiting... (End of file)

On the other hand, playing the extracted dts wav file yields different
output as it tries hwdts and ffdts. It eventually crashes (but eliminating
the printfs eliminates the crash and yields "Cannot find codec 'dts' in
libavcodec...", which is weird because mplayer configure.log contains a yes
result for dts):

MPlayer interrupted by signal 11 in module: init_audio_codec
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't
and
  won't help unless you provide this information when reporting a possible
bug.
