Yes, it seems so. I located it to the line that results in the following

/usr/local/bin/lo10k1 -n --ctrl "c-Left,Right:Wave Playback
Volume,t-Wave Playback Volume:1,c-LeftSurr,RightSurr:Wave Surro
und Playback Volume,t-Wave Surround Playback Volume:1,c-Center:Wave
Center Playback Volume,t-Wave Center Playback Volume:1,c
-LFE:Wave LFE Playback Volume,t-LFE Playback Volume:1" --patch_name
"Wave Multi Volume" -a simple.emu10k1

Apparently c- has to do with "concatenating controls", not sure what it
means... simple.emu10k1 was loaded when I used this instead:

lo10k1 -n --ctrl "" --patch_name "Wave Multi Volume" -a simple.emu10k1

I guess it breaks things...

I launched ld10k1 with -t 7, it says it initializes tram with 1024k.
Whatever that means...

Alsamixer. I understand you can define the whole signal path, and I can
connect/disconnect things but it's not much of a use if I don't know
what's going on. I still need to know how it relates to the hardware...
Digging along...
