Any way to detect speaker volume?

Specs: UNIX/HP-UX
Picture a maintenance app that generates audible alarms when it detects equipment failures in a system. If the techs monitoring the system turn down the volume on the speakers where the alarm sounds are played...so much for audible alarms. The idea has been floated past, that if we had any way of detecting the volume setting of the speakers, we could periodically test for this situation, and on (likely) finding it, present some visual annoyance to prompt operators to turn the volume back up and so "re-enable" their alarms.

Am I right in suspecting that there is no way in creation for either a C or a Java program to detect that the volume control on a standard cheap speaker has been turned down to "effectively off"?

If your maintenance app generated alarm beeps or beep patterns from the mboard, you wouldn't need to be concerned about what the audio volume is set to in the operating system.

Yes, any alarms should use the motherboard speaker.

I like this idea. Where would be best to start, to learn how to do this?
