My HU850 has developed the fault I’ve had before and seen a lot.
controls work but no sound except regular ticking.
Anyway, does anyone know where to get it repaired?

eBay... Unless you know how to do electronics repair, just buy a used HU850 for $100 or so. Not sure if that model needs a security code or not (worst Volvo idea IMHO), but if it does, make sure the seller provides it.
