That the gpio triggered antenna switch on DVB-T doesn't work intrigues
me more, but don't have that card variant.
It can be that I haven't quite grasped how it _should_ work.
I now have the same antenna cable signal connected to both inputs (the cable
signal carries dvb-t, analog tv and fm radio). Albeit identical in theory,
the other input signal is weaker, since I have a splitter in between. Right
now, I have the weaker connected to the analog tv input in the card (the one
closer to the motherboard) and the stronger into the dvb-t/fm.
The one closer to the motherboard is marked CATV-IN on mine. (1043:4862)
The only way I've gotten dvb to work is to
- have the stronger signal cable on the fm/dvb connector
- use the fm tuning trick to switch the gpio to that input
The upper one is marked RF/FM-IN here.
If I connect the stronger signal cable to the analog tv input and do not
invoke the fm tuning trick, dvb does not work.
With the patch in mercurial master now this is correct. It won't work
anymore on the analog/CATV at all. So it seems that the same switch on
your card (1043:4876) happens too.
If I connect the stronger signal cable to the 'fm/dvb-t' connector but do
not use the fm tuning trick, dvb doesn't work.
That's the confusing part for me on your card. For what I found on mine
using radio once does exactly the same as the gpio21 switch now in
asus_p7131_dual_tuner_init in saa7134-dvb.c. Every time a dvb app uses
the tuner the antenna switch happens. Also adding a .mute section
with .gpio 0x0200000 did the trick from the analog side previously.
Analog tv works with both weaker and stronger cable (albeit better with the
stronger signal, obviously).
Should the dvb functionality be able to use either input of the card or just
the 'fm/dvb-t' labeled one?
Previously both were possible, the one marked here RF/FM-IN only after
using radio first. Now with the patch in mercurial master and 2.6.19
DVB-T on mine is always and only at the RF/FM-IN.
I'm sorry for being a bit confused about this. I may have given you unclear
picture on what works and what doesn't.
No problem. Maybe something is different and within the ongoing changes
it is easily confusing anyway. Sorry.
I was up to test again, but after a while realized that DVB-T on the
card is broken currently ...
Also in your case note the new function name introduced with the
Pinnacle 310i patch to get the firmware.
static int philips_tda1004x_request_firmware(struct dvb_frontend *fe,
const struct firmware **fw, char *name)
{
struct saa7134_dev *dev = fe->dvb->priv;
return request_firmware(fw, name, &dev->pci->dev);
}
But first we need to have the card working again. Patch attached.
Hartmut, would you please pick it up?
BTW, thanks for the radio signal and stereo detection!
Cheers,
Hermann

Ok, I will do so. It was me who introduced the bug, sorry!
I did not follow the discussion in detail: In order to fully support
the variant of the card, do i just need to add its PCI ID and change
the firmware request? This should not be a disadvangate for owners of
the old card since the tda10046 will use the eeprom anyway if it finds
one.
There also was a patch regarding remote control, is this ready for
integration? I remember there was an issue with the RC5? toggle bit?
Best regards
Hartmut
