Operating... Yep.  Plug inputs into jackmix, plug jackmix outputs into

QARecord.  Adjust levels.  Ah, did I forgot to turn the computer on ?
Publish to find out ?  Everything works well with Ardour, as I've

mentionned in the original post.  So why bother with apps that I

just about never use and probably will never again ?

I'll see when I'll be doing an audio/jack app.  Then I'll have

details. It could be that I'll never get details about what makes the

jackmix/QARecord fails.  Could be.  Will I be missing much ?  I don't

think so.

Well, this is some kind of conversation, so I figured I'd ask.  Of

course, much information can be gotten without conversation.

Well, if the only way to go was with jackmix/QARecord then yes, a

solution should be found.  But since the problem is easily solved by

simply using Ardour (I always use Ardour by the way and I've never used

jackmix before, and now, thinking about it, in the last two years,

recordings (few, near the beginning) with xruns were done when QARecord

was in the loop) then there's no need to look deeply in the

mechanics of jackmix/QARecord.  If I want to look at some example code

I'll at least look up Ardour because it works well (or any other app

that I can try and works well).
Tschüß, und vielleicht bis später.
