I just downloaded this app on my Samsung Galaxy s7 and on my Windows 10 PC. I successfully sent several photos from my phone to my PC, but the videos that I sent will play on my computer, but they have no sound. I verified that there was sound on the original on my phone. I made sure my computer's sound was turned on. What could be going on? If the videos aren't going to have their sound, this application won't have much use to me at all.
