Yeah, mea culpa. "cardtype=" not "cards=". Check the output of
$ /sbin/modinfo cx18
to see all the options.
As far as rmmod not working, yes MythTV will hold the digital side open.
I usually do
# service mythbackend stop
as root, before removing the module. (I start-up the backend via init
scripts and have it running as user "mythtv". How you stop your
machine's mythbackend may vary from me.)

I had the tuner audio no work for me once or twice in recent weeks on my
single HVR-1600 card machine. Unloading and reloading the module fixed
it.
You may want to apply the attached patch, and see if the problem goes
away "forever" or some statistical approximation thereof.
I think the function the patch fixes up was the critical change that
allows a PCI MMIO write error to go undetected if the readback was a PCI
MMIO read error and we were expecting all 1's, conditioned by a mask,
coming back.
