I can play DVB-T/T2 from CLI using commands:
vlc dvb-t2://frequency=618000000:bandwidth=8 :dvb-adapter=0
vlc dvb-t2://frequency=746000000:bandwidth=8:adapter=0
with any standard DVB-T/T2 dongle (TBS5520SE, PCTV Systems nanoStick T2 290e, etc. ...)

But unable to tune in to the DVB-S/S2/S2X on the TBS5520SE that shows as "adapter 0 frontend 1":
[ 3620.386904] usb 1-1: DVB: registering adapter 0 frontend 0 (TurboSight TBS 5520SE DVB-T/T2/C/C2/ISDB-T)...
[ 3620.387228] usb 1-1: DVB: registering adapter 0 frontend 1 (TurboSight TBS 5520SE DVB-S/S2/S2X)...

I have tried the usual
vlc dvb-s2://frequency=10847000:modulation=8PSK:srate=23000000
vlc dvb-s2://frequency=10847000:modulation=8PSK:srate=23000000 :dvb-adapter=0 :dvb-frontend=1
vlc dvb-s2://frequency=10847000:modulation=8PSK:srate=23000000 :dvb-adapter=0 :dvb-frontend=1 :dvb-polarization=V :dvb-fec=3/4 :dvb-lnb-low=9750000 :dvb-lnb-high=10600000 :dvb-lnb-switch=11700000
vlc dvb-s2://frequency=10847000:modulation=8PSK:srate=23000000 :dvb-adapter=0 :dvb-device=1 :dvb-polarization=V :dvb-fec=3/4 :dvb-lnb-low=9750000 :dvb-lnb-high=10600000 :dvb-lnb-switch=11700000
vlc dvb-s2://frequency=10847000:modulation=8PSK:srate=23000000 :dvb-adapter=0 :dvb-device=1
But none of the commands seem to be working ...
