| Live broadcast without sound | 8,300 | Zhihu, Bilibili | Similar complaints from Huya during the same period |
| Audio decoding error | 5,200 | Technology Forum | New version of FLASH vulnerability |
| 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 transmission protocol upgrade compatibility issues
• CDN node cache abnormality (especially in East China)
• Audio decoding failure in new version of HTML5 player
2.Client issues:Sampling survey shows:
| Device type | Failure rate | Main performance |
|---|---|---|
| Windows PC | 61% | Sound card driver conflict |
| Android | 28% | Permission not granted |
| iOS | 11% | Mute button accidentally pressed |
3.Anchor side configuration issues: Some game anchors reported that the change in the audio sampling rate (44100Hz → 48000Hz) in the OBS streaming settings caused abnormalities.
3. Official response from the platform
The Douyu technical team issued an announcement on August 18 confirming the following problems:
• 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:
• Is browser/APP volume control enabled?
• 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.
