Tracktion default audio output

[Outdoor studio]

With the last tracktion 6 update (6.3.0) appeared problem with the default audio output. In settings page, if choose any of output for default, tracktion keep send audio in channels 1&2 and no in selected output. i try to choose different outputs (any of 24) and sample rates & buffer sizes with no luck. Already i have try to uninstall and install traction software & mixing console drivers. With Tracktion 5 version the problem is little bit different, audio go in selected output channel but still go in channels 1&2 parallel (I do not know if it was something in the past ) but still can work.
With other daw like studio one & cubase lite works normal. I work in PC with windows 7 64bit and for hardware i use presonus studiolive 24.4.2
Sorry for my English
ps:same with tracktion 6.3.1 & tracktion 7 demo

Hi Outdoor studio, are you sure this is the case? We specifically addressed this in 6.3.1 and T7.
If you go to the "Audio Devices" settings page and change the "Default wave output" option the default output should change in the Edits after you restart playback.

If you're not seeing this can you give some step by step instructions as to how to replicate the problem?
