Launchpad Issue: lp1076948

First of all, thanks a lot for the really awesome piece of software that Mixxx is.

I'm running Ubuntu 12.10 and Mixxx 1.10.1~dfsg0-1 (the version from the main archive), and I'm trying to use an NI Traktor Audio 2 sound card as the master output device in the sound preferences.

It's a USB sound card with 2 outputs that's got a working driver in Ubuntu. It works out of the box with PulseAudio apps (e.g. the main sound preferences in Ubuntu, Banshee, Rhythmbox, etc) and with some ALSA apps (e.g. transitionsdj), at least for a single channel output.

However, while it can be initially selected in the sound preferences as an output device, upon clicking on the "Apply" or "OK" button, I get the following error, which stops me from using it:

Error opening soud device "Traktor Audio 2: Traktor Audio 2 (hw:2,0)"
Sample format not supported

I've worked around it by creating a custom .asoundrc file, as documented below. However, I'm reporting this bug as for a better user experience (not every user will be able to create such a file or know that they need to create it) I believe the card should be selectable and usable out of the box with Mixxx.

http://askubuntu.com/q/214749/9781

Here is the relevant log output (TraktorAudio2 is the card I'm refering to):

Is this still an issue with the latest Mixxx 1.11 or Mixxx 1.12 alpha?

The older Native Instruments devices use subdevices, which portaudio does not support. I have the same problem with my Audio4DJ. A .asoundrc or a JACK setup are required to work around the problem.

But, this is not a mixxx bug.

Work is proceeding on trying to fix this bug in portaudio: http://music.columbia.edu/pipermail/portaudio/2015-January/016496.html
