Rispondi a "Does the expansion port include the sd card reader?"The sd reader is it's own separate board inside.. Attached by a short flex cable. 3 screws, easily replaced!
Rispondi a "GoPro Hero4 Silver Not Recording Audio"I'm not at work however I believe the mic is in the top of the rear shell. When I get in tomorrow I will confirm this. There is the three flex cables that go to the board.. Check them, they can be tricky to keep in place during reassembly.
