[linux-dvb] TT budget problem not generating 22 kHz Band switching

I can almost not believe it - nobody has encountered this problem before me ?
(see below, submitted already on Wed. 14 sept.) - Or, I submitted my problem to the wrong list?
If this cards are as widely used as one can see in various publications,
I should not be the first who deals with it.
I have no idea, how this should be caused by my specific hardware/software setup.
I did more tests using the set22k / setvoltage utility included in the dvb-apps -
setvoltage does as expected, set22k does not give any error message, but no tone signal appears.
Maybe there are more specific analysing tools / possibilities (get detailed status from device ....)
Again, please help if anybody has some idea.
Originally submissed article:
Up to now, I used a vdr setup with one TT FF card with CI/CAM with success.
Now, I added a 2nd card (TT budget - ALPS tuner, requested modules dvb-ttpci-budget, stv0299),
encountering the following problem:
on the budget card, I can not receive any transponder in the high band. Analysing the problem
I found out, that the card does not generate the necessary 22kHz signal at all (measured with oscilloscope,
so I can exclude that I deal with a signal level problem!) - after some more tests using dvb-tools
to switch polarisation (works) / low-high band (not working) I concluded to have a malfunctioning card.
The supplier exchanged the card to an other TT budget (philips tuner, requested modules dvb-ttpci-budget-ci, stv0299) exemplar, but the situation did not change.
With this card still no switch to high band possible - same problem.
So, now I think the problem is not in the card - but in the software drivers?!
I tried c't VDR 4 (linuxdvb 1.1.1) and LinVDR 0.7 with same result.
Can anybody give me help, please?
In the moment I have no idea how to proceed - I did not expect to get so serios problems with a TT card,
everywhere they are recommended as best choice.
