| Anchor microphone failure | 3,800 | Douyu Community | Platform Audio Interface Update |
2. Possible cause analysis
1.Technical issues: According to the user feedback timeline, problems broke out intensively after server maintenance on August 15, which may involve:

• Audio load balancing policy bug (hot fixed)
• BUG in the audio preprocessing module of the new version of the APP (expected to be fixed on August 25)
• Conflict in bit rate settings between specific live broadcast rooms (requires host to manually adjust)
4. User self-examination solution
1.basic check:

• System sound mixer checks web tab volume individually
• Try switching to H5/Flash playback mode
2.Advanced processing:
| Problem phenomenon | solution | Applicable scenarios |
|---|---|---|
| There is picture but no sound | Clear the cache and reinstall the plugin | Chrome browser |
| Intermittent voice | Turn off hardware acceleration | Graphics card driver is older |
| No sound in specific live broadcast room | Feedback room number + time period | Anchor push problem |
5. Industry Comparative Observation
During the same period, similar problems also occurred in Huya and Bilibili live broadcasts, which may be related to the following industry trends:
• New radio and television regulations require unified audio coding standards (AAC → Opus)
• DRM copyright audio protection system upgrade for each platform
• QoS policy adjustment in high-concurrency live broadcast scenarios
Conclusion: Audio failures on live broadcast platforms are often caused by multiple factors. It is recommended that users conduct basic troubleshooting first and pay attention to official announcements. The painful period in the process of technological evolution requires platforms and users to cope with it together.
