Hi folks!
I try to run my Native Instruments Traktor Audio 10 (a USB sound card) under pulseaudio but obtain the following behaviour:
Pulseaudio recognises the card via its module-udev-detect. pacmd list correctly identifies it. However, it is not available as output device in pavucontrol.
I can access the card as ALSA device plughw:1,0,0. However, this sends output to every channel at once. All higher channels (plughw:1,0,1-3) cannot be accessed. speaker-test -D plughw:1,0,1 results in Playback open error: -16,Device or resource busy. I could, for a while, live with all channels being accessed but at least I would prefer to access them through pulse.
There is a profile set in /usr/share/pulseaudio/alsa-mixer/profile-sets/native-instruments-traktor-audio10.conf that describes the card for pulseaudio. However, I am not sure whether I need to have additional kernel modules for my sound card.
Does anybody with a similar card (such as Audio 2/4/6/8) know how to get these to work properly under pulse or alsa?

I have traktor audio 6, and you need custom .asoundrc to make it work, check out this tread: http://www.native-instruments.com/forum … ux-support
audio 10 has more outputs so it wont probably work correctly/at all with the same asoundrc, but you could use it as reference.

Thank you!
I could use the last asoundrc in the post you linked to. The additional channels are easy to access. My asoundrc now looks like
pcm.T10_capture {
type dsnoop
ipc_key 1646
slave {
pcm "hw:T10"
period_time 3
period_size 512
buffer_size 32768
rate 48000
channels 10
}
}
pcm.T10_playback {
type dmix
ipc_key 1646
slave {
pcm "hw:T10"
period_time 3
period_size 512
buffer_size 32768
rate 48000
channels 10
}
}
pcm.T10_duplex {
type asym
playback.pcm T10_playback
capture.pcm T10_capture
}
pcm.T10_pair1 {
type plug
ttable.0.0 1.0
ttable.1.1 1.0
slave.pcm T10_duplex
}
pcm.T10_pair2 {
type plug
ttable.0.2 1.0
ttable.1.3 1.0
slave.pcm T10_duplex
}
pcm.T10_pair3 {
type plug
ttable.0.4 1.0
ttable.1.5 1.0
slave.pcm T10_duplex
}
pcm.T10_pair4 {
type plug
ttable.0.6 1.0
ttable.1.7 1.0
slave.pcm T10_duplex
}
pcm.T10_pair5 {
type plug
ttable.0.8 1.0
ttable.1.9 1.0
slave.pcm T10_duplex
}pair1 corresponds to the master output whereas pair2-5 are A-D.
What is your configuration for pulse? My Audio 10 is not attached all the time so I would like pulse to automatically use the devices I defined in my asoundrc whenever I plug in my sound card.

I'm only using traktor with xwax, so I haven't done any configurations with pulseaudio.
Setting the default sink to T10 in pa could probably be enough, I think there are some examples on how to do that in arch wiki.

Thank you again. The issue seems to be more complicated as I need to define appropriate paths etc. I will post updates as soon as I succeed.

I've been trying to get Traktor 6 Audio to work with pulseaudio for some time, and this thread was one of the top search results. Therefore I hope it's ok to necrobump, since everything on this thread is still relevant.
At this time, pulseaudio includes profile-sets for a lot of NI devices, including Audio 6 and 10. However, the profile-sets for at least those two cards are broken.
There's a bug report (that has been dead for quite a while unfortunately), with an attachment for a profile-set that should work with A10, although it's only possible to input/output from all ports simultaneusly, and not from each stereo-pair separately.
Based on that profile-set, I hacked one that works with Traktor A6:
