Yes.

I'm using TvHeadend 4.0.9 for testing DVB-T/T2/C on the Play2, with WeTek modded and supplied Firmware for LibreELEC.
Its a Sony CXD2837 T/T2/C single tuner.

Two demodulators show up in TvHeadend:
DVB-C #0
DVB-T #0

From there it just the standard TvHeadend configuration you would use with any DVB Tuner.
I see no difference with TvHeadend on the Play2, to using any other tuner with TvHeadend and LibreELEC.

 Hi,

I bought a usb tuner that comes with that chip.
I have a KII Pro running Libreelec with TVHeadend but it cannot find the tuner.
Did yours work straight away, or did you need to compile some specific driver for it?

Thank's   

Sometimes you have to install firmware for certain USB sticks - though in my experience LibreElec is pretty good in this regard.  (a 'dmesg | grep dvb' or similar will often show you if firmware has been loaded effectively usually)

Also worth knowing CvH's builds include an option to install specific DVB drivers for Hauppauge (which enables the WinTV Dual HD to run as a dual DVB-T2 device) or Crazy Cat's TBS drivers (as they aren't all in standard builds)
