Audio on a DSLR is considered to be a scratch track, i.e. not recommended for professional use.
When I shoot with a DSLR I use my Tascam DR-70D. It’s an inexpensive 4 channel recorder that takes balanced mic or line level inputs. It has a slate burst signal generator (no hand clap needed) and a jack to send a signal to your DSLR to make syncing things up in the edit suite very easy.
