It appears that /dev/video24 has higher priority than /dev/radio0 at the
time you try to change the frequency:

Try changing the frequency using /dev/video24 .
I don't immediately see any reason in the driver why the priority would
be any different between the two nodes. I can reproduce the problem
with a PVR-350, ivtv-radio, and v4l2-ctl, so it is likely an ivtv driver
bug that is corrupting the driver's card instance data structures. :(

Thanks for making a GUI radio app that takes audio from /dev/video24
(most expect to use ALSA /dev/snd/pcm* nodes). I like listening to FM
radio while I work.
You may also want to look at adding sound capture from ALSA device
nodes. The cx18 driver has a cx18-alsa module that presents an ALSA
interface. I have a long term plan for an ivtv-alsa module to do the
same thing for ivtv.
