Fail to achieve loop playback using B_LOOP

[dsyrock]

Following the behavier in REAPER, B_LOOP=1 should mean that looping is enabled. I attempted to apply this to CF_Preview_SetValue, but the results were unstable. Occasionally, successful continuous looping was achieved with B_LOOP=1, but more often, it would stop on its own after a short period. With B_LOOP=-1, the success rate of loop playback is higher, but interruptions have also been experienced. Could you please advise on factors that may lead to interruptions in loop playback?

It's a boolean so setting anything not 0 is considered a 1 and behaves the same. (This can be observed using CF_Preview_GetValue)

Got more details on the issue you're having with it and how to duplicate? I used B_LOOP yesterday while troubleshooting your section issue and it was working fine then.

EDIT: Is the REAPER window focused (or transport active) the whole time the preview is playing? By default REAPER closes the audio device when inactive (Preferences > Audio > Close audio device when stopped and an application is inactive).

EDIT2: Found a condition where the preview can sometimes be incorrectly destroyed at the loop point. Fixing that...

EDIT3: Builds for testing will be at #1808.
