Random audio corruption

[compucat]

While testing FTL streams with @quarktheawesome, they were able to reliably cause audio corruption in the decoded stream. However, the corruption itself seemed to vary randomly each time the stream was started/stopped. We experienced the following patterns:

• All audio replaced with blurbling noise
• Left channel okay, right channel replaced with full-scale sawtooth wave
• Left channel okay, right channel bitcrushed
• Left channel okay, right channel replaced with full-scale noise

This issue was replicated both on my selfhosted Janus servers (in various geographical locations) and on Glimesh.tv. However, OBS running on my local test machine works just fine. A local recording from OBS does not display the audio issue. Therefore, the issue must lie somewhere within Janus or FTL, but we're not sure if it lies within the sending or receiving side.

Test system info:

• Fedora 33
• OBS 26.1.2 (Fedora build)
• Encoding with x264/opus
