Hello all,
Is there any way to use logical device nammes instead of
'hw:a.b' when setting up Qjackctl ? It seems like the
easiest way to deal with hw device numbers changing on
each boot, but I haven't found a way to do it.
Editing ~/.jackdrc doesn't work, it just gets overwritten
with the (wrong) hw device names (and I wonder why this
is done).
Ciao,
I heard it's also possible to reference cards by unique IDs of some
sort, but this likely only works with interfaces that have a unique
number and I don't remember the details. Florian Faber certainly knows
how to do it.
I use shortnames myself, hw:UA25 here. I remember it's possible to enter
those numbers in the qjackctl GUI.
