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.
