Hauppage HVR1600 - CX18 Issue with Centos 6.2 - Analog Sound comes and goes - MORE DATA

Well I've been reading the mailing lists and found that when I have a Mythtv Capture running and check out performance I get the following:

[root@mythbox bob]# v4l2-ctl -d 2 --log-status | grep 843

If I was compiling from source there appears to be a way to force fallback. How this is done from the modprobe level on a package managed system I have yet to figure out.
