Chimes only come through cluster the last month or so?

Hey guys, have 22 Powerboost, and lately the last month or so, the start up chimes have only been coming through the cluster, and not the speakers. Once in a great while they will come through the speakers like they should/used too. But that is very rare now? Anybody have any idea why this is? Or have it happen to them?

Thank you in advance for any ideas on why this maybe happening?
