Duo2 S2 Twin tuner: second tuner not working

[LOP]

With Duo2 I have two tuners:

• A slot: T-tuner working properly
• B slot: Twin S2 tuner (only B tuner works)

Using latest VIX:
Kernel version: 3.3.8
Firmware version: 3.0.808
Gui version: 2013-12-21

Tuner A: Vuplus DVB-T NIM(CXD1978) (DVB-T)
Tuner B: Vuplus DVB-S NIM(AVL6222) (DVB-S2)
Tuner C: (not working) : Vuplus DVB-S NIM(AVL6222) (DVB-S2)

Both cables are working with tuner B, but not with C. Tuner C is getting signal, but it cannot find any channels. I have already ordered a new twin S2 tuner for a test run. While waiting for a new tuner, do you guys have any idea what might be causing this?

Try to change slots and to connect the dual tuner to the first slot and the DVB-T tuner to the second slot.

Sorry, but this seems to me more like HW issue than SW issue. Sorry for mentioning the current SW in the wrong section.

This issue might be because my Duo2 has too old drivers (12/17/2013).

Newest drivers (12/30/2013) changes:
- Fix dual tuner problem(duo2)

This might do the trick. If not, I try to change the twin tuner in the slot A. After that I'll try with another twin tuner which I received yesterday.
I'll report what happens.

In case of problems, do not forget to test , with change of the tuner priority.
With the old driver there was a bug with C tuner.
I also think it's a better idea to put satellite tuner/s on the first slot.
But maybe tuner priorities,do the same.
