Linux Sparc Sound does not work

[Rafael Diniz <rafael2k@terra.com.br>]

Hello,
I have a Sparc Station IPX with 40Mb of ram, and I want to play musics in
it.
I loaded the succefully the amd7930 sound driver, I did a cat something >
/dev/dsp and it played a nice noise sound.
but, when I tried to do a cat sound.wav > /dev/dsp, the same noise sound
happens.
With mpg123 it returned a error:
Audio device open for 44.1Khz, stereo, 16 bit, failed
Trying 44.1Khz, 8 bit stereo.
SNDCTL_DSP_SETFMT: Invalid Argument
.
.
.

What's the problem?

Thanks
