Your alsa driver/hardware revision seems to be implemented considerably differently from mine. I don't see any explicit output switches. I believe they might be attached to the output volume controls; I will look into this when I have time to do so.

Fixed 2/25/21, for my hardware revision. I will work on a fix that will be compatible with your amixer output, which is rather different from mine.

Fixed 2/25/21. Let me know if the new version doesn't work for you. 1.2.4 seems to assign numid's somewhat non-deterministically. The code has been adapted to reflect that situation.

I am also using alsa 1.2.4 and our numid scheme is totally different. I have never seen this happen before. It might be that you are simply using a newer hardware revision and the driver is assigning the controls to different ID's based on that. At this point, I think the best way to solve this is to poll alsa for the numid's instead of hard-coding them into the software. It will be a bit of a rewrite but I believe that I will have time to implement that solution this week.

No control over interface ALSA 4.18

Fixed

It's the new ALSA, they've broken this program with their updates before; they broke it the same way this time. If there are no hidden side effects, I should have a fix pushed shortly.

This is a bug in alsa, not a bug in qsismix. The controls that qsismix uses to interact with the 6i6 hardware should be listed under amixer controls, but for some unknown reason are not available under some system configurations. A possible work-around is to disable pulseaudio when you want to use alsa's mixer controls, although I am not sure that pulseaudio is always the culprit and pulse runs along with alsa on my system without issue.
