Why does Plex fail to see BOTH tuners? All other indications on my system show 2 tuners, not 1.

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)

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.”

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.
