Chris G Hi. Trying to set up my tuner in Ubuntu. I downloaded this (http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/dvb-demod-si2168-02.fw) firmware and put it in /lib/firmware chris@chris-VirtualBox:~$ dmesg | grep si2 [ 15.500939] si2168 2-0064: Silicon Labs Si2168-B40 successfully identified [ 15.500942] si2168 2-0064: firmware version: B 4.0.2 [ 15.580839] si2157 3-0060: Silicon Labs Si2147/2148/2157/2158 successfully attached Still don't see it in TVHeadend though. Any ideas? Chris EDIT: Using the version of TVH from the Ubuntu store

Harry Developer 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.
Saen Acro No DVB adapter registered ls /dev/dvb or better tree /dev/dvb https://www.linuxtv.org/wiki/index.php/PCTV_Systems_tripleStick_T2_(292e)
Chris G 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
Joe User 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.
Chris G 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.
Chris G 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. Chris
