How to play mono files with CamillaDSP EQ

[Sehnsucht]

When playing a mono (genuine single channel, as opposed to two channels each with the same content) mp3 with a CamillaDSP config, I get an error instead of lovely music:

Code:

Oct 24 10:00:15.911 ERRO Use of non existing channel 1, module: camilladsp
Oct 24 10:00 : output: Failed to play on "ALSA Default" (alsa): snd_pcm_poll_descriptors_revents() failed: No such device
Oct 24 10:00 : exception: Failed to open audio output

Is there some solution where I can play one or two channel music with a CamillaDSP preset without having to create another preset and selecting that one each time I want to listen to mono files?
