V4l failing to create compound device

Server Version#: 1.41.3.9314
Player Version#: 4.141.0
Tuner Make/Model: Hauppauge WinTV-QuadHD-ATSC [card=57,autodetected]

We had a recent power outage and when I brought the server back up live tv was disabled and showing no active devices. When I try to re-enable or bring live tv backup I get an error stating there are no devices found.

If I look at the Tuner logs this is error I see each time I attempt to open the live tv configuration screen from the webui.

I’m able to use the hauppauge card in other applications to watch tv, so I believe the card is loaded and working fine. I’ve done a bunch of searching around but have failed to come up with any answers.

After spending some time with the web and just trying out a bunch of things I was finally able to get the cards working normally. I just had to wipe out the right files to get it to re-init everything.

systemctl stop plexmediaserver
