Never did. It's possible that the I/O board was affected when the charging port was damaged. My dog came running bye and got tangled in the cord, destroying the port and sending the laptop flying.  I bought a pair of bluetooth speakers which worked fine. I've since replaced it with an X17R1 (with accidental damage coverage).
I had to tear down my M17 R3 to replace a damaged charging port. While I was at it I repasted the processor. The new charging port works and my thermals are much better, however I no longer have sound. Not only do the speakers not work, but the headphone jack and built in microphone don't work either. I took everything back apart and rechecked all the cable connections. In particular, I made sure that the cable to the right I/O board was properly connected as that appears to be where the sound devices reside or are connected. Still no luck. Reinstalled drivers - still nothing. I ran the full diagnostics on Dell's support site - no errors reported. Is there something I am missing or should be checking?
