Official Patch Notes
OBS Studio 32.1.1 is an archived hotfix in the 32.1 line. It mainly addressed audio mixer regressions after the 32.1 audio mixer overhaul, including missing tooltips, oversized mixer width, sorting problems, disabled sources appearing in the mixer, missing toolbar actions, incorrect colors, and an audio monitoring deduplication issue. This record is retained for rollback and context because 32.1.2 replaced it as the better maintained hotfix.
