I posted a question in November about PMS being unable to detect the usb Win-TV tuner installed on my computer, that had previously worked with PMS.
I haven’t had a response, beyond ChuckPA adding the PVR tag to my post.
So where do I go next; how do I escalate this?
I’m a paid up lifetime Plexpass holder, so is there premium support?
I seem to be having the same problem. Win-TV tuner was working a few weeks ago but after upgrading the server to the latest my DVR setup was removed and now when I try to setup DVR again the tuner isn’t detected. Did you get your issue fixed? Did you find a way to escalate? I just paid for a year subscription and now want to cancel or at least pause it until this is fixed.
Which tuner
Hi BigWheel, my post about the tuner is here. It is a winTV DualHD usb stick.
I’m considering reverting to an older Plex version once I can figure out how to do that and not have to reset all my clients.
Tuner isn’t officially supported on Ubuntu 19 with Plex, you could save off the /var/lib plex directory and revert to 18.

WinTV-Dual HD by Hauppauge. I’m running server version 1.18.3.2156 after the upgrade. I’m on Windows 10 unlike Jamesbloke.
I thought the whole point of installing via a Snap was to get away from all that? Regardless, in the Unsupported Tuner’s page it states that many unsupported tuners still work, they just have to conform to the Linux DVB API. Well, the WinTV DualHD is working and all I have ever installed is the DVB API.
Reverting back to Ubuntu 18 is not an option, that would be too disruptive to the other services running on my box.
Reverting Plex version on Snap was not possible. Might see if I can do this via PPA instead.
Okay…reverting PMS via PPA was not possible, spent a long time trying to work out how, eventually found that you can download a .deb package and spent another long while trying to work out how to download older versions.
Tried to install 1.15.8 and 1.16.2, but both times I got a DPKG error 1 at the end of the install using terminal.
I did note a verbose message about not having Udev installed, before the DPKG error 1. I have checked and Udev version 242-7ubuntu3.2 is installed.
I have just tried a WinTV PCIe tuner with PMS 1.18.3.2156 on Windows and discovery was ok.
Test the tuner setup with the WinTV application - not sure if there is one on Linux but they do provide instructions for setup on the linked article https://www.hauppauge.com/pages/support/support_linux.html#plex
If the tuner is accessible then restart Plex Media Server, wait 5 minutes as we need to make sure the PlexTunerService application is running - then go through DVR Setup. Select Create DVR - wait 20 seconds or so - because I have seen old device entries in the database may interfere and we may need to wait for timeout
If device does not appear after 20-30 seconds, take a screenshot and collect the server logs. Make sure debug logging was enabled for the server before restarting the server for this test

Thanks SA2000, the WinTV stick works on the linux box fine. Plex now reinstalled through the app store, which is about the fourth uninstall/reinstall done. Service restarted as requested. Log and pictures below. Noticed libusb_init failed when restarting the service. restarted service again, same libusb message.
ran:
Blockquote
sudo snap connect plexmediaserver:raw-usb
and restarted plex service. libusb error gone, still no tv tuner in plex.
The Plex logs show these errors repeatedly

These were logged by the Plex Tuner Service process - which was started at this time

There are some old forum topics mentioning this error
libusb_init returned an error -99
I will discuss this with the team
Would like to see logs when the DVR is not found and there is np
Have re-run the logs again as requested.

Thank you. The error changed.
What is showing now is a permissions error -

There is a forum post here wintv-dualhd not working properly with Live TV - #2 by keithah which mentions
Try doing ‘sudo usermod -a -G video plex’ to give the plex user access to the video group, which is likely where /dev/dvb/adapter1/frontend0 lives and you should be good to go.
Could you look into this. The command is mentioned on this web page
That was done at first install when it worked. User/group details below.
james@Twiki:~$ grep video /etc/group
video:x:44:plex
james@Twiki:~$ /bin/grep plex /etc/group
video:x:44:plex
plex:x:127:james,
Thanks
I have come across this - is this a screen for snap applications? I have not got a linux machine to check.
Interesting. I don’t have access to the desktop currently, so I have interogated Snap permissions from terminal:
james@Twiki:~$ snap connections plexmediaserver

https://snapcraft.io/docs/supported-interfaces lists DVB separately from usb.
The dvb interface
dvballows access to all DVB (Digital Video Broadcasting) devices and APIs.
However:
james@Twiki:~$ sudo snap connect plexmediaserver:dvb
error: snap "plexmediaserver" has no plug named "dvb"
disabled snap service
installed PMS via PPA and set up a test server.
WinTV working.
So, I guess I have to switch to the PPA and switch all my clients to the PPA…and re-import my media…and re-check my media as played…and put up with the manual update messages.
I guess that means it is snap specific and probably is the dvb plug I noted above.
I guess I also found the answer to what other support there is when the forum doesn’t deliver.
