Dear all,
Anybody any clue what the following JACK message means?
"ports used in attemped connection are not of the same data type"
since JACK has only 2 data types at present, it implies that you were
trying to connect audio& MIDI ports.
Hello Paul,
That is the point, I wasn't doing that deliberately. This message
appears with practically every audio connection I try to make. And I'm
using QjackCtl which doesn't allow for making that kind of connections
afaik.
But at least I know what it means, thanks (pretty straighttforward
though, should've figured it out myself). And indeed, easy to reproduce
on the command line:
jack_connect system:capture_1 yoshimi:midi\ in
Results in a "ports used in attemped connection are not of the same data
type" message (with a little typo). Now my question remains why it appears.
I have 2 USB audio devices - one a USB sound card, the other a MIDI
connection. Sometimes JACKDMP 1.9.2 insists on trying to use the MIDI
device as an audio OUT port.
I don't know why. Usually goes away if I leave the MIDI connection
unplugged when I start the computer up, or simply tell QJackCtl to use
the appropriate hardware-numbered port. But it could be related to the
fact that sometimes the built-in Intel audio chip appears, and sometimes
it doesn't!
