Has anyone been able to control the volume of the VMUSIC module? I have everything else working, I have all the docs, but can't get the volume control code to work. Would love to see a line of sample code..

I guess I needed to bang on this a little earlier into the morning.. I finally figured it out!

I'm having the same problem, I've succesfully controller it via Zterm, like 'play', 'stop' etc but not sure what commands I need to send it to control the volume, any help much appreciated.

You have to send commands to the decoder chip (VS1003) to handle that. See the VDAP Firmware Specification for the commands VWR/VRD to accomplish this. You will need specs for the VS1003 to know what you’re setting there or some example code from someone who knows the commands. Take care.
