gidday mate... it does sound like a failure in the audio output stage. I suggest that you first check the speakers for short circuits as a fault here will produce a similar symptom you described. Check that you have the correct DC conditions about the STK, such as main power supply. Check all resistors that are in proximity to the STK, particularly lower value ones. Look also for shorted or dry capacitors about the output stages. Most of the audio signal path amplification is inside the STK and generally only a few millivolts of audio are provided to the input pins(usually the outermost pins). I have looked online for a data sheet on the chip that may be of help to you, but have not yet been able to find one. If the unit has soft touch electronically switched input selectors or electronic attenuator to the vol control, either of these IC,s may be faulty also. I am happy to keep going with this to help you fix it if you want. Give me a hoy back in here and I will :)

The gain dial is not a volume control. The gain dial is used to compensate the output level of your car radio head unit. all car stereo units output are not alike. If you set this gain level too high, it will cause major distortion (clipping) to the audio output of you speakers when cranked up. This excessive distortion WILL eventually, or even quickly damage or blow your speakers.
I personally blown speakers this way no not properly setting this. (lesson learned, I guess :| )

I read another post that says that if turn on the unit and set the volume where you want it at startup, and then press in the volume knob until you hear it beep, that locks in the current volume as the startup volume. I just read this, so I haven't tried it myself yet. Good luck!

Go to Device Manager and up date your drivers if this don't fix the issue. Try removing the driver and visit http://www.acer.com/worldwide/selection.html select your location.
