The amd7930 chips are only 8-bit mono in capacity. If you want to dump sound directly to the /dev/audio you need to make sure it's an 8-bit Sun .AU file or it will produce nothing but noise. You can use the sox package to convert from .WAV to .AU with no problems. You might be able to use some package that plays .WAV files directly but I'm not sure which one will work for you or if one exists for Sparc.
As for mpg123 - I use it with the -r 8000 and 8 bit mono settings and it will play music just fine. (I'm using an IPX as my .MP3 alarm clock personally. *grin*) It will _not_ do stereo - probably because of the speed of the machine. I've tried. It comes out slow and/or choppy. If you want to play .MP3 files you should probably get an LX with at least 32meg of ram and the latest Debian Sparc kernel that supports the DBRI audio properly. That's what's _hopefully_ going to be my in-card .MP3 player. (I already have such a machine built I just have to find a good way to put it in the car. ;-) Hope this clears things up a little!

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?
