Server Version#: 1.18.4.2171
I was trying to troubleshoot an issue I was having with an Ubuntu 18.04 server rebuild and found this thread:
I have a Hauppauge WinTV-HVR2250 tuner in the server and it wasn’t recognized by plex. Found this support page Hauppauge Support | Running WinTV TV tuners and HD PVR 2 under Linux but when I followed the instructions it didn’t fix my problem. What did was this line in the post which supposedly didn’t apply:
sudo apt-get install linux-firmware-hauppauge
My system now sees the PCI tuner.
