Tvheadend

Hi ! I'm using tvheadend with Astrometa DVB-T2 device on Linux Mint.
After reinstall linox on my laptop, with new tvheadend tvheadend not searching channels.

If uninstall tvheadend with w_scan have channels. Reinstall tvheadend againg, setting tv adapters,network, muxes but not find any channels.
How it's possible to make tvheadend working again ??

Before install tvheadend i-m copy this firmware in /lib/firmware and reboot laptop.

On 2016 i-m make a little tutorial with settings for this device: http://satelit-info.com/phpBB3/viewtopic.php?f=157&t=2446&p=20179&hilit=astrometa+in+ubuntu#p19940 but now nost scanning any channels.
