Since Hauppauge have now released PPA files for modern versions of Ubuntu I thought I’d give them a try on my Ubunbtu 17.04 box with Plex 1.7.4.4017 (also just upgraded 1.7.5.4035 and still seeing the same issue)
After following the instructions on the Linux Plex Support page (http://www.hauppauge.com/site/support/linux.html) including the usermod Plex sees the tuner fine but whenever I try a scan for channels it reports that nothing is found (tried both selecting the relevant transmitter directly and also scanning all UK DVB-T frequencies)
However if I plug the tuner into a windows box running the same version of Plex and run the scan it picks up all the channels I would expect.
Anyone have any suggestions for next steps to identify what the problem might be ?
After my 2nd exchange with Hauppage, I am less convinced it is the same problem as in the earlier thread they pointed me to (https://forums.plex.tv/discussion/274302/wintv-dualhd-kernel-4-8-0-plex-1-7-2-3878-8088811b8), as there the w_scan output actually fails to see the device at all (“main:3904: FATAL: ***** NO USEABLE TERRCABLE_ATSC CARD FOUND. *****”), whereas in my case w_scan sees the device but finds no channels.
Are you running the server or desktop version of Ubuntu 17.04? Hauppage’s first reply to me suggested they knew there was a problem for Ubuntu server.
Sorry for the slow reply I’d kind of forgotten about all this but thanks to your updated in your thread neonwombat I’ve been able to fix this !
It was the missing firmware so the info you mentioned was just the pointer I was looking for, but I needed a slightly different file. I don’t know why this was, it may be the UK version of the Dual Tuner is slightly different or it could be because I have a Ubuntu 17.04 Desktop installation with a 4.10 Kernel.
But dmesg was showing it was trying to load the firmware files but getting a -22 error so I went hunting for alternative versions of the firmware and found http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/
From there I WGETed dvb-demod-si2168-02.fw direct into the /lib/firmware directory and suddenly w_scan is reporting signal and Plex is finding channels !
