OSS and PulseAudio give /dev/dsp as a device.

I did some checking and it looks like OSS 4x is already installed but I could be wrong.

From that POV there SHOULD be a device /dev/dsp available...

See if it exists ls /dev/dsp to check.

If it does try this:-

cat /dev/urandom > /dev/dsp

OR

cat /dev/random > /dev/dsp

(Ctrl-C to stop it.)

Are you using your Solaris in Terminal, Console or GUI, (Gnome?), mode?

EDIT:

Quote:

Which showed my /tmp/sox.log totally barren.

It might give a result somethng like this:-

Code:

cat /tmp/sox.log
/Users/barrywalker/sox-14.4.2/sox WARN rate: rate clipped 3330 samples; decrease volume?
/Users/barrywalker/sox-14.4.2/sox WARN sox: `coreaudio' output clipped 3292 samples; decrease volume?

This is a warning only and only comes on _input_ or _output_ overload.

As you have an empty log then it suggests to me that you either have an external input selected.
The output level is fixed at OFF.
The input level is switched OFF.

If you remove the '-q' from the sox command and run you should see something like this:-

Code:

cat /tmp/sox.log

/tmp/noise.raw:

 File Size: 65.5k     Bit Rate: 64.0k
  Encoding: Unsigned PCM  
  Channels: 1 @ 8-bit    
Samplerate: 8000Hz       
Replaygain: off         
  Duration: 00:00:08.19  

In:25.0% 00:00:02.05 [00:00:06.14] Out:88.2k [!=====|=====!] Hd:0.0 Clip:6.50k
/Users/barrywalker/sox-14.4.2/sox WARN rate: rate clipped 3217 samples; decrease volume?
/Users/barrywalker/sox-14.4.2/sox WARN sox: `coreaudio' output clipped 3286 samples; decrease volume?
Done.

If you see the !=====|=====! then you have output but the volume is OFF.
If you see the ! | ! then you may or may not have output, but the input source is possibly wrong or OFF.

SYNOPSIS

       play [fopts] infile [effect]

       rec [fopts] outfile [effect]

DESCRIPTION

       This manual page briefly documents the play and rec commands.

       play  and  rec are programs that allow you to play and record different types of sound files from the command line.  They are front ends to
       the more general sox(1) package.  Normally, the play command will automatically detect the type and other parameters of the  soundfile.	If
       it can't do so, the parameters can be changed through options.

OPTIONS

       A summary of common options are included below.	For a complete description of options and their values, see the sox(1) man page.

       -c [channels], --channels=[channels]
	      Define the number of channels in the file.

       -d [device], --device=[device]
	      Specify a different device to play the sound file to.

       -f [format], --format=[format]
	      Specify bit format of the sample. One of s, u, U, A, a, or g.

       -r [rate], --rate=[rate]
	      Specify the sample rate of the audio data (samples per second).

       -s [size], --size=[size]
	      Specify the width of each sample.  One of b, w, l, f, d, or D.

       -t [type], --type=[type]
	      Specify audio file format to use.  Useful if it can not be automatically determined.

       -v [volume], --volume=[volume]
	      Change the audio volume

       -x , --xinu
	      Reverse the byte order of the sample (only works with 16 and 32-bit data).

       -h, --help
	      Show summary of options.

       --version
	      Show version of play/rec.

       Description of effects are described in the
