I have a sx520hs that has no audio input, only 'A/V out' (miniUSB->RCA) and 'miniHDMI out'. I've seen some cameras that have a USB port that accepts a adapter (USB->TRS) that turn that usb av out into a 'audio in'. Is that a way to make that usb av out an audio input? I know I can sync video to external audio, but it becomes to be very annoying when its about dozens of cuts.
Thank you.
