PMsounds and CPFlight Fire test bell and Sys test

[CBruce]

I have the cpflight fire module and their MIP which has the sys test button. I have tested the cpflight hardware is all working ok via their test program. But when I activate the cpflight fire test bell, the cpflight fire module lights up all ok, but no sound of the fire bell, even though I can see it is there in pmsounds.

Same with the sys test which should play the warning/advisory sounds in pmsounds.

Anyone got this to work? I have ticketed PM but no answer to date
