The way you are doing it (audio via the camera) should be ok, as long as you are matching levels and matching balanced audio with balanced audio and line level and impedance with line level and impedance (some cameras are setup for mic inputs which are different to the line level that will come out of your mixer, and some again have only un balanced or only balanced and some mixers have either or.
You can use a DI or balancing or un balancing unit to take care of the conversion. Alternately, you can also get an embedder and embed the audio into SDI or HDMI just before it goes to media express.
You cannot select your soundcard as an input in media express, only the audio inputs on the blackmagic capture device will work. What capture card are you using (I am guessing a ultrastudio mini with only HDMI or SDI? What camera do you have? What is your audio source, and is it balanced or unbalanced? Alternately you can also convert to digital AES/EBU and feed directly into the ATEM and use the ATEMs audio mixer to route the digital input to the feed.
Many ways to do this, if the system is setup right the audio should be good, I would guess there is a missmatch somewhere.
