OSMC TV dongle not finding Panasonic (DVB-T2) tuner

Help and Support Raspberry Pi

Hi,

Pi3 with OSMC remote and OSMC TV dongle (and 2.5A psu) running OSMC March 2018.

I’m very basic with linux, just enough to break things…

TVHeadend installed and running OK, but on cold boot it only lists the Realtek tuner (DVB-T) under Config > DVB Inputs > TV Adaptors. My workaround is

sudo service tvheadend stop
rm /home/osmc/.hts/tvheadend/input/linuxdvb/adapters/9d84dad05c885fe8d8a91db0bf0c47ce
sudo service tvheadend start

ie deleting the adaptor config. TVH then lists all 3 tuners, I just have to re-enable them and associate with the Network. I’m then set until a reboot.

dmesg has these

6.304607] usbcore: registered new interface driver brcmfmac

[ 6.418403] usb 1-1.5: DVB: registering adapter 0 frontend 1 (Panasonic MN88473)…

and then this warning…

usb 1-1.5: DVB: adapter 0 frontend 1 frequency 0 out of range (42000000..1002000000)

…which is weird because that’s the Realtek tuner, and none of my muxes are out of range.

Let me know if there’s more detail/logs needed. Cheers.

Oh and I guess this might be relevant - the contents of the file I keep deleting in my workaround at /home/osmc/.hts/tvheadend/input/linuxdvb/adapters/

I have found that you should not try to enable both tuners at once. It won’t do you any good anyway because they can’t run in parallel. So just enable the panny and you are good.

That’s right. The Panasonic offers a superset of functionality; so using the other modules is not necessary.

Gah this worked, disabled the Realtek and restarted TVH/OMSC a few times and it comes up fast and smooth.

So, cheers, but also feedback as a consumer experience - yeesh. I’ve been using it for a few months thinking it was just an SD tuner (there has also been a freeview mux move on my transmitter that confused matters) and “maybe I should try disabling the one visible tuner in TVH” was not very high up my list of possible cures. For buying hardware from the software provider, this didn’t go well! Maybe you could revise the App Store TVH distro to do this?

Thanks guys,
