Can you try to load the driver with the 'card=9' module option? Based on the
.inf file the correct GPIO to enable the AGC is GPIO 0x0c, while the currently
selected card uses GPIO 0x1c. Card 9 (Hauppauge USB Live 2) is identical to
card 5, except for using GPIO 0x0c. So I am hopeful that switching to card 9
will fix this issue.

Instead of using the card=9 option you can also try this patch:

diff --git a/drivers/media/usb/cx231xx/cx231xx-cards.c b/drivers/media/usb/cx231xx/cx231xx-cards.c
