Expected Behavior

OBS should run a live stream without crashing some time later. Audio devices should remain stable, and the application should not unexpectedly terminate.

Current Behavior

OBS crashes randomly during a live stream with an error. The crash log indicates the issue is related to audio handling (audio_output_disconnect, stop_audio_encoders, and end_data_capture_thread), suggesting a problem with how OBS manages audio devices during the stream.

Steps to Reproduce

1. Start OBS Studio
2. Use Aitum Multistream to stream to multiple platforms, including Twitch.
3. At some point during the stream (unpredictable timing), OBS crashes.
4. The Twitch stream stops, but other platforms continue broadcasting.

Anything else we should know?

• The issue is inconsistent and can happen anywhere from 10 minutes to several hours after starting OBS.
• I have tried reinstalling OBS and even reinstalling Windows, but the issue still persists.
• The crash happens with no clear pattern, which makes it difficult to predict or consistently reproduce.
• It may be related to how OBS/Aitum Multistream handles Twitch’s audio stream.

Start by reviewing the attached OBS log and crash log, focusing on the reported audio_output_disconnect, stop_audio_encoders, and end_data_capture_thread entries. Compare the failure with the Aitum Multistream and Twitch setup, then seek a reliably reproducible disconnect scenario. Done means identifying a confirmed cause and preventing the crash without stopping unrelated streams.
