Hi, I recently purchased a HauppaugeTV-quadHD DVB-T/T2/C tuner in Australia. I followed the guide on linuxtv.org available here: https://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-quadHD_(DVB-T/T2/C) I installed the dvb-demod-si2168-b40-01.fw firmware file. Device nodes for the card are present: /dev/dvb/adapter3 /dev/dvb/adapter3/net0 /dev/dvb/adapter3/dvr0 /dev/dvb/adapter3/demux0 /dev/dvb/adapter3/frontend0 /dev/dvb/adapter2 /dev/dvb/adapter2/net0 /dev/dvb/adapter2/dvr0 /dev/dvb/adapter2/demux0 /dev/dvb/adapter2/frontend0 /dev/dvb/adapter1 /dev/dvb/adapter1/net0 /dev/dvb/adapter1/dvr0 /dev/dvb/adapter1/demux0 /dev/dvb/adapter1/frontend0 /dev/dvb/adapter0 /dev/dvb/adapter0/net0 /dev/dvb/adapter0/dvr0 /dev/dvb/adapter0/demux0 /dev/dvb/adapter0/frontend0 I cannot get any dvb-t application to work. TvHeadend detects the adapters, but is unable to scan. w_scan fails too, for example: $ ./w_scan -c AU w_scan version 20170107 (compiled for DVB API 5.10) using settings for AUSTRALIA DVB aerial DVB-T AU scan type TERRESTRIAL, channellist 3 output format vdr-2.0 WARNING: could not guess your codepage.
