On my 2015 retina MBP, running Handbrake 1.0.1, on Sierra, I get no audio on the .M4V files I am trying to create from old .mov files. With the exact same file, on my 2012 MBP, running Handbrake 0.10.0, on El Capitan 10.11.6, I get audio perfectly as it should be on the .M4V files I am creating from the same exact .mov files. I would prefer to use my 2015 machine as it's a quad core processor and will be able to handle the 850+ videos that need to be converted in a batch much faster than my other machine.... but I'm running out of options and need to get them converted. Any ideas why the difference? Thanks!
