Mr Lelegard,
Thank you so much for your kindness and quick response.
Before contacting Dektec, here is what I did tonight (If it helps to someone else):

...
... WORKED perfectly....
So the original issue seems to be resolved, thank you so much, and I will close it.
For other readers, my personal lessons learned:
-
Don't trust your kernel, try with other kernels ( Looking at you my ex company )
-
tsresync stops at first sync failure, thats why we need "-c / --continue" . Check filesizes after fixing sync.
-
Notice the satellite-frequency is in Hz , but Symbol Rate is in symbols/second. This was quite confusing unless you RTFM.
-
When selecting the modulation frequency, it is quite different than what you see in Streamxpress. In the StreamXpress, modulation frequency is selected as 966000 , which corresponds to intermediate frequency ( 9750 + 966 = 10716 Mhz ) , but in TSP, you can directly write 11750 Mhz because you can define LNB as well. It seems to calculate corresponding IF automatically .
-
TODOs: try all DVB-S/T/C modulation options , try RF Level adjustments, check if there is a progressbar in tsp, recompile tsduck from scratch to get rid of this libsrt issue.
-
Finally, I should write a blog post named "How to use DTU-315 with TSduck for dummies like me",
Thank you again,
Best.

Hi,
There is no need to rebuild the deb package. If you are not familiar with dkms, the purpose of such a package is to install the source code of the driver somewhere in the system, only once. This source code is automatically recompiled each time the kernel is upgraded. And of course compiled the first time during installation of the package. From your logs, we can see that the driver was correctly recompiled. Then, it failed to load.
Without such a dkms package, you are obliged to manually recompile the driver from the Dektec-provided LinuxSDK.
The deb package in this project is just repackaging of the Dektec source code and build procedure into the dkms infrastructure.
Here, you build the Dektec driver and it fails to load. This is a problem to be addressed by Dektec. Since you purchased a DTU-315, you are a Dektec customer and may ask for support.
