I've got a NI Traktor Audio 2 sound card I'd like to get working with Mixxx, but I don't seem to have any success so far. The card seems to be supported in Ubuntu out of the box, and it seems to work well with ALSA, but I cannot select it in Mixxx and I'm not sure whether is something I can do to make it see it (e.g. through).
So for testing purposes, on the command line I can execute aplay to check each channel:
aplay -D plughw:2,0,0 test.wav
aplay -D plughw:2,0,1 test.wav
That works well: I can hear the test sound on each channel (A and B)
The relevant output for this card using
aplay -D is:
hw:CARD=TraktorAudio2,DEV=0 Traktor Audio 2, Traktor Audio 2 Direct hardware device without any conversions plughw:CARD=TraktorAudio2,DEV=0 Traktor Audio 2, Traktor Audio 2 Hardware device with all software conversions
From those 2 items on the output,
plughw is the one that works, whereas
The problem is that Mixxx only lets me select the
hw card, which does not seem to work. I'd like to be able to select the
plughw card, which is the one that's working.
I've tried suspending Pulse Audio as suggested by this question, but that did not seem to work. I also played around with an
.asoundrc file similar to the one on this answer (which was for an older model of this sound card), but also without success.
Any ideas on how to make Mixxx show the right card (and channel, while we are at it)?
