Yes, I enabled the DVB-T tuner in Tvheadened frontend DVB Inputs -> TV Adapters (pick the Enabled checkbox and set the network to my predefined), because with the new configuration is automatically "deactivated" while the HTSP Client say: No free tuner available.
After enabled DVB-T in Tvheadend frontend (and set Network and 'Maximum PIDs' to 26) changed HTSP Client message from "No free tuner avaliable" to "No signal"Unfortunately I could not find a solution
Thank for report. I did only blind dvb-t test as I have no athenna at home. Tomorrow morning I'll be tested it at my work.
