Darren,
Could you please try the cx18 driver at this repository:
http://linuxtv.org/hg/~awalls/cx18-audio
?
In two patches, I've reworked when the audio detection microcontroller's
soft and hard resets are asserted.
If those two patches don't seem to work, please change
linux/drivers/media/video/cx18/cx18-av-core.h
#define CXADEC_AUDIO_SOFT_RESET 0x810
to be
#define CXADEC_AUDIO_SOFT_RESET 0x9cc
and then see if the patches work. (I've got some conflicting
information on which register is actually the soft reset register.)
I haven't tested any of this, as I don't have an analog RF signal handy
ATM.
Regards,
Andy
