"Echo in Audio Calls and Framerate/Audio Issues in Video Calls on Baresip with RPI Zero and ReSpeaker Pi Hat 2"

[Brij Kumar]

Hello everyone,
I’ve set up Baresip on an RPI Zero with a ReSpeaker Pi Hat 2 for the microphone and speaker, using PoE. While the setup works, I’m encountering a few issues:

1. Audio Calls: There is a significant echo during audio calls, which affects the call quality.
2. Video Calls: The framerate drops during video calls, and when this happens, the audio quality also degrades—sometimes the audio cuts out entirely.

Has anyone experienced similar issues with echo, framerate drops, or audio problems in a similar setup? Any advice or recommendations on resolving these would be greatly appreciated!

Thanks
