this is pointless. there is no difference between this and -d hw:1

k 1.9.8, qjackctl 0.3.8.

I've chosen my USB audio interface for capture and playback -- .jackdrc=
looks like this:

/usr/bin/jackd -P70 -dalsa -r44100 -p1024 -n2 -D -Chw:1 -Phw:1,0this is pointless. there is no difference between this and -=
d hw:1=A0

But, when qjackctl starts jack, it uses -Chw:0 -Phw:0.

What's even more strange is that it was working yesterday. Today, no lu=
ck. No matter what I choose for the capture and playback devices, it always=
uses the laptop's built-in hardware. But, if I run the jackd command i=
n the terminal, it DOES use the right device. So it seems simply that qjack=
ctl is issuing the wrong command.

As another test, I changed the hardware buffer size, but that is used corre=
ctly. So it's only the devices.

I've heard of other problems with qjackctl vs. jackdbus -- is qjackctl =
the wrong tool? What is the right tool?

Sorry if this is too basic a question. jackaudio.org is, unfortunately, no help at all: I would=
have thought the page about "Configuring and running a JACK server&qu=
ot; would explain:

http://trac.jackaudio.org/wiki/WalkThrough/User/GettingSt=
arted

... but it's empty.

Help...?
