Did you check if it works stand alone? E.g. using dvbscan or w_scan? See https://www.linuxtv.org/wiki/index.php/Dvbscan for details. You might need to stop tvh to prevent the device to be locked.

No DVB adapter registered

ls /dev/dvb
or better
tree /dev/dvb

https://www.linuxtv.org/wiki/index.php/PCTV_Systems_tripleStick_T2_(292e)

I have only tried in TVH so far. I will see if I can get it working with another utility.

Here is the output

@chris@chris-VirtualBox:~$ tree /dev/dvb
/dev/dvb
`-- adapter0 |-- demux0 |-- dvr0 |-- frontend0
`-- net0

1 directory, 4 files
chris@chris-VirtualBox:~$ ls /dev/dvb
adapter0

Looks like apparmor is blocking access. You need to look at apparmor settings. Sorry, I do not use it so I can't offer much help.

Yes. I dissabled apparmour following a guide but then TVH stopped working. Had to reinstall ubuntu because it wouldnt let me re enable it using the same guide.
Looked into making a profile but didnt seem to do anything.

Use regular not SNAP version.
Too much virtualisation.

You mean dont use the ubuntu store version?

EDIT: well it seems using the Ubuntu store version was the problem. I installed manually following the guide on the wiki and right away my tuner was detected.

Sorry to waste your guys' time.

just for test
or enable snap container in apparmor if possible
