[QUESTION] audio delay with only a few frames loss

[iququ]

When our device receives audio (no video), the delay may reach 2.2 seconds gradually within 15 minutes. We meansure the delay of the RtcOnFrame callback registered via transceiverOnFrame(). Our handling of the audio frame is in another thread so it would not block receiving audio. From onFrameDroppedFunc() warnings, there were only 14 frames dropped, which is just 280ms.

Could you guide us on find out where the issue is? We already tried to change DEFAULT_JITTER_BUFFER_MAX_LATENCY to 100ms, but no help. Thanks.
