I have both the PII (first) and PI (second) versions of David Moberg's 
mplayer, as well as mpg123 from Slackware.

On two PII computers, mpg123 works fine, mplayer for PII will not play 
sounds but it will convert (-ao pcm) to a wav file which you can then play 
with a script, using sox/play.

I now have a computer with Intel PIII 605 MHz cpu, which replaced an Asus 
board (350MHz K6) which would NOT play stereo .wav files in linux (but 
would play them in DOS, or mono wav files in linux).  Stereo files gave me 
an error message about IRQ/DRQ config error.

I have the same hard drive that I was using in the Asus board.

I can now play wav files with sox/play.
I tried mpg123 on an mp3 file that worked on another computer, also on one 
I found online:

Playing MPEG stream from vivaldi.mp3 ....
MEPG 1.0 layer III, 128 kbit/s, 44100 Hz stereo
Sound:  DMA (output) time out - IRQ/DRQ config error?
(After a few lines of this I hit Ctrl-C).

I then tried out both mplayers.
The first player (for P2) plays .wav files perfectly.
The second player is not expected to do so.

I then tried to play an mp3 file with the first player:
Starting playback...
A:   0.3 0.0% 0%
(Nothing else happens).  I also tried online and got the same results.

So I tried the 'mplay' script to play the same MP3 file with the second 
player (which uses mplayer to convert to wav and play that).  I know that 
the play part works.

mplay vivaldi.mp3  (this works on the PI, same software, same mp3 file)

On the PII 600MHz:

Mplayer 1.0pre5-3.4.3 (C) 2000-2004 Mplayer Team
CPU:  Intel Pentium III Katmai/Pentium III Xeon Tanner 601.4 MHz (Family: 
6, Stepping: 3)
Detected cache-line size is 32 bytes

(It stops here).

Same result from mplayer -ao pcm vivaldi.mp3
or mplayer -ao oss vivaldi.mp3

So I can now play .wav files on the new computer with sox/play but not mp3 
files with either mpg123 (IRQ/DRQ config error) or mplayer for the PI
(cache-line size is 32 bytes) or mplayer for PII (Starting playback.... 
A:  0.3 0.0% 0%).

I have not tried playing the library DVD.  Hopefully DVD sound is .wav not 
.mp3.  I can play .wav with play or mplayer on here, just not mp3s.
The 233 Mhz PI continues to play mp3s nicely via mplayer -ao pcm and 
'play', on or offline.

The phone line is fixed but had nothing to do with the problem (or the 
fact that my 56K modem connects at 31K ;=( ).

Any idea how to get around the IRQ/DRQ config error with mpg123?  Or why 
neither version of mplayer will play mp3s but will play wavs?

I get the same result trying to play an ogg with the PII player.
Ogg:  bad packet in stream 0
A:  0.7 2.0% 0%

mplay -- Detected cache-line size is 32 bytes.

I can play this file on the PI with the other player (complete with bad 
packet message).

I did not try the 350MHz board with K6, which would not play wav file 
with sox/play, using mpg123 or mplayer for PI.

I am starting to be surprised when anything works right with sound.

I might try a non-awe64 sound card next, but I had 'play' problems in 
another ASUS board with a non-awe card.
