Fedora 9/CCRMA based system, Delta 1010,
18.104.22.168-1.rt13.4.fc9.ccrma.i686.rt kernel (usually)
jackdmp 1.9.1, Ardour 2.7.1 (both pre-built and hand-compiled)
/usr/bin/jackd -R -P70 -p512 -dalsa -r44100 -p128 -n2 -D -Chw:0 -Phw:0 -m
Prologue: it helps to understand that in my Ardour sessions, I have
the master bus output going only to the monitor bus, and the monitor bus
outputs connect only to the system:playback inputs. I then control the
volume to the powered monitors with the fader for the monitor bus.
I started up an Ardour session today to listen to a band I'd recently
recorded with Ardour 2.7.1, and heard feedback that started quietly but
started growing rather quickly. I turned down the amp and saw the
master bus's VU meters full on into the red, with the monitor channel
about half that.
I pulled up the master bus input list and saw this:
ardour:Drum Submix/out 1
ardour:Vox FXout 1
ardour:Marty Guitar/out 1
ardour:Harry guitar/out 1
ardour:Drum Submix/out 2
ardour:Vox FXout 2
ardour:Marty Guitar/out 2
ardour:Harry guitar/out 2
'Ere, what's all this then? Master outs in the master in? That ain't right!
So I click on the master/out 1 item, and it goes away. I click on the
master/out 2 item, and it goes away... but it brings back the master/out 1
I open the master outputs, and see this:
Ports 1 and 2 are fine, but 5 and 6 go to the mixer. Odd, but it
shouldn't matter, since the mixer's got everything down right now.
Let me just remove playback_5, I don't need it. Now for 6... oh
sh!+, I take 6 out but it pops 5 back.
What's in the monitor input?
Auditioner? Do I use it? let's try and remove it.... Nope, I can
take one out but the other pops back.
Oddly enough, the real buses are fine. I can remove the monitor
inputs from the master outputs fine. It's only these odd ports that
I haven't used in the session.
I've opened other sessions and found the same problems. If I look at
the session.ardour file, there's no mention of the Auditioner or the
playback 5&6 ports.
Not weird enough for you yet?? I just opened the session under
another login on the system (non-root), and it's fine. No oddball
non-removeable ports, no feedback, no problems whatsoever.
Anyone got a clue as to what's happening here?
