The resolution is in the 3rd last paragraph below. I took notes with the testing procedure and am sharing this as a reference, if anyone searches this topic later on. If ever :) The hardware wiring goes like this. The 1 and 2 line outs of the 1010LT card are going into the HS8 subwoofer. From the HS8 a XLR cable goes to one HS5 speaker and another XLR cable goes to th other HS5 speaker. The physical hardware volumes knobs on both HS5 are set the same. I use Bitwig with one only track in which a continuous single-oscillator 'init' synth sound is played. The master stereo output of Bitwig is defined as 'Speakers-R' and 'Speakers-L' and is assigned to system playback 1 and 2 respectively. I use qjackctl to switch on/off the Bitwig stereo out for playback 1 and 2. Playbacks 1 and 2 are connected by default to Bitwig's master stereo Speakers output. The sound is heard. Using qjackctl both outputs from Bitwig are disconnected from the playback inputs. No sound is heard. I throw the panning knob of both the track and the master to the left. No sound is heard. I connect Speakers-R to playback 2. No sound is heard. This is all OK so far since the sound should be total left. I disconnect Speakers-R from playback 2 and connect Speakers-L to playback 1. Problem: the sound is clearly heard in both speakers. Even though the pan is full left on both track and master. All right ! Found it. Using Envy24 control app, I see in the Patchbay/Router tab that H/W Out 1 and 2 were directed to 'Digital Mix 1' and 'Digital Mix 2'. I set them instead to 'PCM out 1' and 'PCM out 2' and the sound is then only heard on the left, as it should be. Disconnecting playback left and connecting playback right confirmed this. Then throwing the panning to the right confirmed this also. This is great ! The stereo sound through those HS speakers is really nice. More to the point, the stereo pad sounds from a couple of Repro-5 polyphonic emulations of the a Sequential Circuits synth. Cheers.
