DVBlast streaming frontend failed

[ZawiszaCzarny]

Hi,
I ran TVaheadend on a raspberry 3 b to check if the cards work and it looks like everything is ok. I am able to watch programs from each of the cards (that's how I checked if the cards work).
TV adapters
|-/dev/dvb/adapter0 [Sony CXD2880 #0]
| |- Sony CXD2880 #0 : DVB-T - #0
|
|-/dev/dvb/adapter1 [Realtek RTL2832 (DVB-T)#1]
| |-Realtek RTL2832 (DVB-T)#1 : DVB-T - #0
| |-Sony CDX2837ER DVB-T/T2/C demodulator#1 : DVB-C - #1
| |-Sony CDX2837ER DVB-T/T2/C demodulator#1 : DVB-T - #1

Then I have enabled streaming via dvblast for the "adapter0" card:
dvblast -a 0 -c /dci/config/dvblast/mux2.cfg -f 538000000 -b 8 -i 1 -5 DVBT2
and it went OK
however when I try on adapter1
dvblast -a 1 -c /dci/config/dvblast/mux2.cfg -f 538000000 -b 8 -i 1 -5 DVBT2
I get the following error

I also try this to force dedicated frontend but no success :
dvblast -a 1 -n 1 -c /dci/config/dvblast/mux2.cfg -f 538000000 -b 8 -i 1 -5 DVBT2

How can I get dvblast to stream on adapter1

This is VLC forum. Not many people here are familiar with DVblast to say the least

Can we use MuMuDVB to stream DVB-T2 multiplexes (hevc/h.265)?
