ffmpeg – from DTS-ES “7 channels” to 7 mono wave channel files

I have this DTS file: audio_dts_es.dts
I need to have 7 mono channel wav files.

Mediainfo show this:

ffmpeg show this:

Input #0, dts, from '.\audio_dts_es.dts':
  Duration: 02:02:33.74, start: 0.000000, bitrate: 1535 kb/s
  Stream #0:0: Audio: dts (dca) (DTS), 48000 Hz, 5.1(side), fltp, 1536 kb/s

“List channel names and standard channel layouts” –> HERE

How can I demux corretly?

Is it correct?

ffmpeg -hide_banner -i 'audio_dts_es.dts'
-filter_complex "channelsplit=channel_layout=6.1[FC][FL][FR][SL][SR][BC][LFE]"
-map "[FC]" -c:a pcm_s24le "output_audio_FC.wav"
-map "[FL]" -c:a pcm_s24le "output_audio_FL.wav"
-map "[FR]" -c:a pcm_s24le "output_audio_FR.wav"
-map "[SL]" -c:a pcm_s24le "output_audio_SL.wav"
-map "[SR]" -c:a pcm_s24le "output_audio_SR.wav"
-map "[BC]" -c:a pcm_s24le "output_audio_BC.wav"
-map "[LFE]" -c:a pcm_s24le "output_audio_LFE.wav"

Thanks!

PS
the command above give me the “output_audio_SR.wav” without any audio inside.. why?
