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.

GLSWEEP(1)						      General Commands Manual							GLSWEEP(1)

NAME

       glsweep - a program generating log sweep and inverse filter.

SYNOPSIS

       glsweep [parameters] sweepfile inversefile

       Usage: glsweep rate amplitude hzstart hzend duration silence leadin leadout sweepfile inversefile

       Example: glsweep 44100 0.5 10 21000 45 2 0.05 0.005 sweep.pcm inverse.pcm

DESCRIPTION

       This manual page documents briefly the glsweep program.	This manual page was written for the Debian distribution because the original pro-
       gram does not have a manual page.

       glsweep is program to perform accurate time aligned impulse response measurements.

       glsweep is based on the log sweep method for impulse response measurement, which is one of the most accurate, especially for acoustic  mea-
       surements. This method is based on a special signal, which is a logarithmic sinusoidal sweep, that need to be reproduced through the system
       under test, and an inverse filter, which, when convolved with the measured log sweep, gives back the impulse response of the system.

       The output format is the usual raw file with 32 bit IEEE floating point samples. If you need to convert the sweep generated using the exam-
       ple above to a 16 bit mono WAV file you can use SoX with a command line like this one:

       sox -t f32 -r 44100 -c 1 sweep.pcm -t wav -c 1 sweep.wav

PARAMETERS

       rate:	    reference sample rate
       amplitude:   sweep amplitude
       hzstart:     sweep start frequency
       hzend:	    sweep end frequency
       duration:    sweep duration in seconds
       silence:     leading and trailing silence duration in seconds
       leadin:	    leading window length as a fraction of duration
       leadout:     trailing window length as a fraction of duration
       sweepfile:   sweep file name
       inversefile: inverse sweep file name

       Refer to html documentation for more details.
