if amux LINE2 doesn't work it is usually LINE1.
If both don't work, there is a external gpio controlled switch/mux chip.

Default is loop through for external audio in.
Means, if the saa7134 driver is unloaded, should be passed through to
audio out. If not, there is such a mux chip involved.

Should not be a problem anymore, since you have already unique codes for
all keys. 

It works with the same gpios, but generates different codes and the MCE
remote has more and different buttons. We likely need a new entry for
the T750F later and will have auto detection problems, because of the
same PCI subsystem. Detecting from eeprom does not work well with two
different remotes.

This is currently because the ir init happens already at hardware init
level 1, but epprom detection nedds working i2c at hardware level init
2. Unless ir init is not moved to hardware init 2, it needs to set the
card=number option to get the right keymap then.

Hm, if I get it right, without using windows previously the XCeive at
0x61 is not found and then it is tried in vain to use the qt1010 at
0x62.

Also, after using windows gpio20 seems to be high.
Maybe that is the gpio to get the tuner out of reset.

Please try the attached patch as a shot into the dark.

We could use that 0xc6 byte for eeprom detection.
I don't know what it means here, but in this one 0xc4 is the qt1010
DVB-T tuner, 0x1e the demodulator and 0xc2 the analog tuner.

No, I pay attention when I test for channel that XCeive gets recognized
as 0x61. When I do cold boot, or windows reboot its always gets
recognized at 0x61. Sometimes (I don't know exactly what triggers that)
the 0x61 gets omitted, and the result is that XCeive get recognized as
0x62. The result is that channel is not showing any more, apparently.

I think that xc2028-27.fw file load failures triggers that behavior,
because when I reboot linux with loading firmware failures, that
behavior is showing (from what I have noticed).

Sorry for the gpio alert, but I did some logging, and the gpio value
varies, and depends on computer state. But it seems that is same in both
cases after all. (details http://pastebin.com/f4c511dfc)

I tried your patch, too, and it's not working. Thank you for trying.

Hi Samuel,

thanks for that clarification.

I don't know, if Markus has something better in his binary blob
meanwhile, he was initially interested at least, but how to comment on
stuff not shown anymore ...

At least, the remote will be operable for cheap.

Does anybody know, why Compro doesn't clear the eeprom byte for the
analog demodulator since years (0x86)? F* it.

Cheers,
Hermann

Well, I haven't managed to get sound from Audio In connector, it's  
possible however that I'm doing something wrong. I tried selecting in  
tvtime both Composite and S-Video, and I've tried using SoX:
console$> ls /dev/dsp*
dsp dsp1
console$> sox -c 2 -s -r 32000 -t ossdsp /dev/dsp1 -t ossdsp -r 32000  
/dev/dsp &

for both .amux = LINE1 and LINE2 in saa7134-cards.c source file.




RegSpy log:

I have used RegSpy that comes with DScaler version 4.1.15. I'm hoping that  
they are of some use for both Analog television and Audio In.

I have found out values crucial to changing inputs for both audio and  
video. Note that SAA7134_GPIO_GPSTATUS keeps changing all the time between  
84ff00 and 94bf00 nevertheless of the device status.

I have used VirtualDub (v1.7.7) as capturing application because it gives  
more control on input selecting (I can change audio input, not depending  
on video). From that I manage to distinguish values changing between video  
and audio.

The crucial value for video seems to be SAA7134_ANALOG_IN_CTRL1 while for  
audio seems to be values SAA7133_AUDIO_CLOCK_NOMINAL and  
SAA7133_PLL_CONTROL.

Hi Samuel,

the above link still gives error not found.

For an external audio mux it is always a single gpio pin for that.

It is some same pin in the same state for composite and s-video,
but different for TV mode.

The above seems not to show such a pattern.

Also you missed to print GPIO_GPMODE, which is the gpio mask.
In that, pins actively used for switching are high, but m$ drivers do
often also have for that specific card unrelated pins high.

Gpio 8 to 15 are the remote gpios and gpio18 should be the key
press/release.

The rest above seems not to be consistent for what we are searching for.

If you get some time again, do a cold boot and dump the gpio mode and
state before any application did use the card.

Then dump analog TV, composite and s-video and anything else you can
test. The GPMODE and the GPSTATUS on top of any mode used is what is
really interesting.

It also prints the state of all gpios for each mode in binary, so if you
manually mark the states you used, one can just copy and paste line by
line and see the changing pins.

As said, it should be a pin in the mask/GPMODE being the same for
composite and s-video, but different for analog TV. Maybe better use the
Compro software to get the logs.

Cheers,
Hermann

Strange, because to me works just fine. I'm going to add it directly as an

As I mentioned before GPSTATUS keeps changing all the time (And I mean  
frequent, measurable in miliseconds), and it seems that it hasn't any  
connection between other values.

That is at least good ;)
Mask changes have been seen previously too.

Looked at it yesterday, but for an external gpio driven amux it seems
not to have anything consistent.

For an gpio switch of an external amux, that pin would be high in the
mask for all what was seen previously. Nothing like that.

Eventually gpio-27 high could mean something for the tuner, but why it
should mean something when virtualdub works for the tuner without it?

I leave it to those more experienced.

Cheers,
