  Success!

I've tracked down the offending change. switch_addr takes on the wrong value
and setting the LNA fails. Here's a i2c dump:

tda827x: AGC2 gain is: 10
                       ^ The gain reported on good kernels is 3 

Looking at the source, the switch_addr to use in the later kernels is somehow 
autodetected. How that's done, I've yet to fully understand, but somehow it 
comes up with the wrong address.

This patch (which obviously needs improvement) hardwires the address back to 
its original value, and works for 2.6.30-rc5.



Could you please help me out and shed some light on what the proper fix is for 
setting switch_addr? 

Thanks,
/Anders

thanks a lot for all your time and energy you did spend on this.

I suggest we start collecting photographs of different LNA circuits on
the wiki.

For now, Tom offered his support already off list, I think we should
start about the question, if that early Hauppauge HVR 1110 has such an
LNA type one at all, since this caused to not look at it further, as it
seemed to be without problems.

Tom, I know you carefully worked on it, but can you reassure that this
LNA config one is really needed on your device?

Cheers,
Hermann

Do you want me to open up the case and take some photos of the board? Any
particular circuit I should look for?

Well, this is a Pinnacle 310i, not a Hauppauge. At least acording to the box 
it came in! Are we talking about two different cards here?

well, the point is that Hauppauge bought Pinnacle recently concerning
capture cards, but hat is Europe for now.

The 310i and HVR 1110 are the only cards using config one for LNA
support.

I can provide a photograph for LNA config type two on a Ausus OEM 3in1.

Don't use any brute force. On recent cards it is easy to remove the
upper tuner shielding, but on early cards, the 310i is likely such a
one, the shielding was completely soldered. Then better stay away!

Please have some patience. I have Steven and Mike in CC, but allow them
to have lots of time. Else we must start some better hacking attempts
again later.

Cheers,
Hermann

Hello list,
you are talking about tuner_config = 1 for the hvr 1110, right ?
Changing this option doesn't affect the qualitie of the signal on tv
see http://forum.ubuntu-fr.org/viewtopic.php?pid=1472261
it 's an "old" discussion in french.
This option, as far as i remenber, was not provided by me ...

anyway with tuner debug=1 and .tuner_config=1 , i have no line with AGC 
or LNA on dmesg

I have somme glitchs with hvr1110 on dvb (not analogic tv) and many for 
one particular station call M6 (and i'm not the only one user, see 
previous post on ubuntu-fr.org, with short or long distance from tv 
relay) . Bug on 310i means potentially bug on hvr1110 as configuration 
on hvr 1110 was made from 310i

and sorry for bad english

Cheers,

thomas

No. We're talking about the switch_addr variable. This variable is not 
changeable with module parameters.

You only get this output if you enable debugging. Here's what i have (gentoo):
anders@tv /etc/modprobe.d $ grep '' saa7134 saa7134_alsa tda827x tda8290 tuner
saa7134:options saa7134 disable_ir=1 alsa=1 core_debug=1 i2c_debug=1
saa7134:#options saa7134 alsa=1
saa7134_alsa:options saa7134_alsa debug=1
tda827x:options tda827x debug=1
tda8290:options tda8290 debug=1
tuner:options tuner debug=1

If you adjust your module options similarly, you'll get more info in dmesg.

If you're ok with patching kernel source, could you try the patch I sent?

I've never tried my 310i on digital (dvb-t), so I'm afraid I cannot help you 
there. I use it on analogue cable tv.
