Describe the bug

My sip is peer to peer without register! I used "class extraaudiodevice" according to your prompt, but there was another problem: "alsa_dev.c pb_thread_func: underrun! 22:35:14.339 alsa_dev.c ca_thread_func: overrun! scombdb-dn Underflow, buf_ cnt=173, will generate 1 frame”。

At the same time, the problem of sound lagging behind video still exists, and I don't know whether the sound lagging behind is related to the video 3S and the log prompt. How can I analyze and solve this problem? I'm very anxious. If you have any offense, please forgive me.

Steps to reproduce

Thank you very much. My sip is peer to peer without register! I used "class extraaudiodevice" according to your prompt, but there was another problem: "alsa_dev.c pb_thread_func: underrun! 22:35:14.339 alsa_dev.c ca_thread_func: overrun! scombdb-dn Underflow, buf_ cnt=173, will generate 1 frame”。
