okay, this was my fault.
I was too enthusiastic about PVR things in Kodi.
I had "VDR PVR Backend" installed and enabled in Kodi too. It got the dvb device before tvheadend.
How did I discover that? From ssh logi:
LibreELEC:~ # lsof |grep dvb
927 /storage/.kodi/addons/service.multimedia.vdr-addon/bin/vdr.bin /dev/dvb/adapter0/frontend0
Hi,
Trying to expand Kodi to take care of TV, I picked up an AverMedia TD310.
Shows up in Linux dmesg output ok:

Is there a magic piece of glue that I'm missing?
