Loud pop then no sound from the speakers

Driving back from a holiday last week, heard a very loud pop and hiss from the speakers (seemed to come more from front left), then no sound at all. the normal chimes etc. are all coming from the instrument cluster.
I've tried the following:
Reset SYNC (next and power button)
disconnect battery
checked for DTCs - nothing relevant
ran all self tests on modules - all tested goo
All my research has been pointing to a faulty/damaged ACM, however the self test showed no issues. Another suggestion was that a speaker may have somehow shorted out. I've checked the resistance across the coils on the fronts, will check the rears another day.
Has anyone else experienced anything similar or could offer any assistance?
Cheers,
