nope, no audio settings in the Hyperdeck mini, well other than to select the number of channels recorded. SDI embedded audio only carries what is fed into it, you can't change what's in the SDI stream without going through a processing device. And BTW, HDMI audio can only carry 8 channels of audio. The entire ATEM line only supports 2ch audio.
plug your ATEM HDMI output directly into a monitor and listen for quality there. it's good then the SDI>HDMI is causing the distortion. If it's a BMD converter I recommend updating its firmware. the ATEM outputs 1080p, older firmware did have audio issues with this at one point. current converter firmware works well.
If the audio is bad in the monitor then the problem is upstream and either in the ATEM, or the source feeding the ATEM. you have listened to the cable going into the ATEM to check quality there, right?
I've tested this with a line level source into my ATEM mini, HDMI out thru a Decimator and recorded to a Hyperdeck Mini-playback was flawless and distortion free so it's possible to get a good thru-put and recording.
EDIT-it comes to mind you never mentioned what you have going on in the ATEM mixer. Are other channels turned on, or just the mic input with your external feed? if your entire mix is on the mic input, i'd make sure you have all other faders turned off.
