Damn good information to have. Where is that sort
of information documented?
Not really. But the ice1712 is the same chip used for the delta1010
which has 8 analog and one s/pdif pair. I just guessed... and kept
trying inputs till I found it. I also have the USBDualTubePre and had to
find out with my Delta66... I use inputs 1,2,3,4,9,10 ...
Or you can start Jackd first and then set audacity to talk to
jack instead of alsa or pulse. You can use qjackctl to connect
audacity to channel 9 for recording. To see levels hit pause
and record... infact you will have to do this before you
connect ports with qjackctl.
This seems most promising to me.
I have audacity started up and in "pause/record mode".
I have qjackctl started up.
But I don't really know where to go from here. I have
hit the qjackctl "Connect" button, and see both the
"Audio" and "Alsa" tab. Perhaps you direct me where to
go next or direct me to some documentation?
Audacity uses the portaudio library to connect to Jackd.. so in the
qjackctl connections window and the audio tab you should see PortAudio
on the right side. Connect system/capture_9 to PortAudio/in_* (the * is
a number that changes every time you hit record) and you should see the
left meter showing audio. You may wish to disconnect whatever audacity
auto connects first. The only documentation to look for portaudio is in
the audacity setup screen where you set up jack it says:
Using: PortAudio V19 bla bla bla
My experience with recording via Audacity using JACK is that the
PortAudio connection only appears in JACK while Audacity is actually
using it (playing or recording). So I guess you start recording in
Audacity, pause it, tweak the connections in JACK, then continue recording.
I record using a USB card that has only 2 inputs, so I've never had to
tweak the connections JACK provides.
