You can have audio going out a different HDMI port. In the myth audio setup
find the output that match the port. It will be either a ALSA:hw or
ALSA:hdmi

Try them all, you will need to configure video output on that hdmi port too
even if it’s not going to be seen ultimately, you can’t have just audio.

If your TV supports ARC, there are ARC extractor that would do the trick ;
the advantage over using the optical port of the TV is that you can do
lossless audio.
