Raspberry Pi TV HAT inaccessibility issues

Hi All

I did and encountered the following:

Installed LibreELEC on Raspberry Pi 4, with a TVhat tuner card. Set up and configured TVheadend so that I was able to do the following:

• Watch live TV.

• Record what I was watching.

I then did the following (I’m not entirely sure what order I did them in):

• Attempted to configure TVheadend to record to a USB stick.

• Set up a few scheduled recordings and two of them clashed.

This resulted in the following situation:

• Initially being unable to watch live TV because it said there was no spare TV adaptor (although a couple of reboots seemed to fix this).

• However whenever I tried any scheduling or recording I started getting the same error, reboots did not fix it and now I cannot even see the Tuner in the TVheadend Web Configuration or under /dev/dvb/.

A week or two later, on one of the occasions that I was turning the Pi on, I was able to access the tuner through the TVHeadend web page and was also able to view the device in /dev/dvb/ (I had tried to plug in another USB TV tuner, I don't know whether this had any impact). I was then able watch and record live TV but in attempting to configure both the tuners I lost access to both as indicated above and as of yet have not been able to access the TVhat tuner again.

I did take a look a dmesg but was unable to make much sense of that as I wasn't really sure what I was looking for.

Is anyone able to offer any advice? Thanks.

Hi CvH

Thanks for the response.

My understanding was that you can if they are on the same mux? Which was what I was hoping for, if there was any overlap when I was testing scheduled recordings. Primarily though, I've had conflicts in Kodi before (on a different device) and they have not resulted losing access to the TV tuner altogether, which is the part that I would like to avoid, particularly if I don't know how to fix it.
