Tuner not being released when live TV stopped on Kodi

[dark_half]

I m using Kodi as the frontend for NPVR. I am having issues where the tuners are not being released when I stop playback of live TV. I have experienced the issue with bot HD-PVR2 and HDHomerun tuners. Typically I have to restart the recording service to correct but sometimes I can correct it by starting, stopping, or changing channels several times on live tv as is shown in the attached logs from both NPVR and Kodi. Below I started live TV the stopped but the tuner wasn't released. I then selected the same channel and started live TV again and upon stopping the tuner still wasn't released. On the the third try I switched to a different channel and when I stopped the tuner was released. I kind of pieced the 3 logs together below to give a timeline. These instances were within a few minutes so I could capture a short log but I have seen the tuner stay locked for hours after live TV was stopped.

This is a common error I've seen in the logs in timeshift after the socket is supposed to have been closed but the web server keeps the tuner open.

Martin is the problem with NPVR, NPVR addon in Kodi or Kodi? I assume since you didn't give any recommendations there currently isn't a fix for this?

NextPVR is closed source so hard to say but this particular error looks to be related to how the server responds to the socket close. The timeshift protocol is prone to other errors though which makes it hard to diagnose properly. Real time or extended time shit modes for Kodi might be better for you.

The NextPVR addon in Kodi is currently configured for Real Time. I will play with the other two options and see if there is any improvement. Thank you for your assistance.

Having the same problem where NextPVR and Kodi will not release my HDHomerun Dual tuner unless I unplug the tuner.  Any solutions to fix this problem?  Log attached.

[mvallevand]

That is because you enabled the optional feature to keep the tuner primed

You have 'Keep digital tuners primed' on the Settings->Devices page. You can untick that to release the tuner after each use.
