auplay and nas

["Cimarron Ryan" <cryan mail wesleyan edu>]

Here's a fun project:  I want to use mpg123 and auplay to listen to my mp3's
when I'm at an x terminal.  I know everything's set up properly, cuz, I can

$auplay myfile.wav

without difficulty.  The problem, of course, is that auplay can't handle
mp3's.  So I'd like to use mpg123 to convert the file to wav format,
downsample to 22kHz (so the music doesn't skip) and pipe the resulting
stream to auplay. Here's what happens:

[cryan cryan cryan]$ mpg123 -2 --wav - confusion.mp3 | auplay

Comment: Track 12                        Genre: Techno

Playing MPEG stream from confusion.mp3 ...
MPEG 1.0 layer III, 128 kbit/s, 44100 Hz joint-stereo
Couldn't play file "-"
Broken pipe
[cryan cryan cryan]$

It looks like auplay can't handle reading from stdout...  Just for the heck
of it, I also tried

[cryan cryan cryan]$auplay <(cat mine.wav)
Couldn't play file "/dev/fd/3"
[cryan cryan cryan]$

Any ideas on how to get a program that doesn't like to read from stdout or a
named pipe to do so?
