there are different models of the HVR-1110 we can see onhauppauge_eeprom down in saa7134-cards.c.
Some don't even have analog audio in.
In case it is there, if the current LINE2 stereo input pair doesn'twork, then it is LINE1.
If that still does not work, you can expect an external gpio driven muxchip on the board. On cards with analog audio out it can be fairly easytested by unloading the driver. Default is then to loop the soundthrough to the analog output of the card to the soundcard, but with thedriver unloaded you can't test, since you need saa7134-alsa for itwithout having analog audio out connected on the card.
In that case regspy.exe from DScaler (deinterlace.sf.net) might help.
A work around could be to plug the external analog sound directly intothe sound card/chip and record from there.
Was the radio ever tested? Since the tda8275ac1 has only one RF signalinput pin and the card has two antenna connectors, we usually see thatthese inputs are switched on gpio21 including the AutoGainControl andusing the 5.5MHz ceramic filter for radio input.
See the other cards with TUNER_PHILIPS_TDA8290.
Mostly it is high (0x0200000) for the radio switch, only sometimes theother way round. Then you must set .gpio = 0x0200000 for the TV inputwith the same gpio_mask.
Cheers,Hermann
