[SOLVED] So.....

[sjoens]

what did I do???

One mono audio track plays hard left and one mono track plays hard right when both Pan knobs are -0-.

All track settings look right for playing dead center.

Converting to stereo and panning opposite results in silence even though you can see wave form on both channels.

Interleave button changes nothing.

No FX.  No bus.  No automation.

If I create a new audio track and copy the audio clip there it plays dead center as it should.

pan law settings? corrupt audio file?

[sjoens]

Since only one response out of 80+ viewers I can only assume this is a rare event.

Pan law is 0 and never touched.  Audio files seem ok as they play correctly in a new track.  So... old tracks must be corrupted?!

Any rate, they are now replaced with new tracks properly panned.

I can only guess without a screenshot that shows the track header and routing. A console view shot ?

Tracks were deleted but appeared as any new track would, Pan knobs simply didn't work.

I finally traced the issue to a 2020 project that was saved in x32 SPlat.   The last good project was also saved in x32 SPlat.  The problem is there when opened in SPlat so SPlat is to blame.  I haven't worked on those particular tracks since then so didn't notice the issue until now.

Same track with Pan set 3 ways resulting in same left output.  Bus plugin is stereo Sonitus Equalizer.

The other track panned hard right affected the same way.

quick test in Sonar - two tracks hard panned, out to buss A, plus sends to an Aux track as well, stereo as expected. with or without the Sonitus EQ. for me it seems to be working as expected.

• each source track was set to mono interleave with a mono clip.
• buss = stereo interleave, aux = stereo interleave
• no FX, no PC on any tracks or buss
• no solo settings
• latest Sonar

second test - still works on Sonar

• used stereo interleave on all tracks
• added PC EQ w/ boost on ~1200hz
• turned on solo on source tracks
• used Sonitus EQ on buss A with a couple of boosts

I was curious if I had done something to cause it but now I don't think it's something that can be reproduced intentionally and may have happened during one of CbB's frequent crashes or hanging in Background Processes.  AAR the offending tracks are replaced with new ones in the latest saved project...  so far so good.

Turns out I had saved several sequential projects that have the bad tracks but they will lie dormant until deleted.

Just going back to your original post. Are you 100% sure that the interleave does nothing?

 

[sjoens]

Well it does change the track icon as it should but doesn't change the sound or Pan of the output.  Something disabled the Pan function permanently locking the tracks in the hard panned state they were in.  I could post before and after screenshots showing this.
