My Plex DVR only shows 1 tuner in the GUI:

Whereas, /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Logs/ Plex Media Tuner.log indicates the presence of 2 tuners: (file attached)

Whereas, the linux /dev filesystem indicates the presence of 2 tuners:

My System:

OS: Ubuntu 17.10 (supported via Hauppauge PPA)
uname: uname -a
Linux daumas-media 4.13.0-19201712311231-generic #0+mediatree+hauppauge-Ubuntu SMP Sun Dec 31 21:14:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Plex: Version 1.11.0.4666

According to Hauppauge tech:

[Paraphrasing]: “The OS can see both tuners so it isn’t a Hauppauge driver problem. Check with Plex.”

Check out the below link. There is a patch to make the 2nd tuner show up.

As stated in my write-up, the 2nd tuner is already visible to the OS. Patching the kernel is unnecessary as the current kernel driver, as updated via the Hauppauge PPA, already presents both tuners to the Plex application, as follows:

# ls -l /dev/dvb
total 0
drwxr-xr-x 2 root root 120 Jan 25 13:21 adapter0
drwxr-xr-x 2 root root 120 Jan 25 13:21 adapter1

It is only Plex that cannot see the 2nd one. Why?

Bump… anyone have any insight into this problem?

Thus far, the provided suggestions point to kernel patches which make the tuners appear. In my case, the tuners ALREADY appear under ubuntu 17.10 with kernel 4.13, and the mediatree-hauppauge driver updates.

I reiterate, the problem is that PLEX cannot see both tuners, yet the OS already can.

I am having the same problem. :cry:

I have two WinTV-dualHD’s:

What happens when you click on “Add Device”

It just displays that forever

Here are the Plex Tuner Service Log

Plex seems to find all the tuners but does not display them
