ALSA lib pcm.c:8306:(snd_pcm_recover) 发生欠载

Question

我正在尝试在 python 中使用 socket 和 pyaudio 编写语音聊天。我写了它并且它有效，但它引发了这些错误

ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) 无法打开从站

ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) 未知 PCM 卡.pcm.rear

ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) 未知 PCM 卡.pcm.center_lfe

ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) 未知 PCM 卡.pcm.side

ALSA lib pcm_route.c:867:(find_matching_chmap) 找不到匹配的通道图

ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) 无法打开从站

它不断提高这个：

ALSA lib pcm.c:8306:(snd_pcm_recover) 发生欠载"

我在接收和播放声音的 Server.py 中得到这些。如何解决？
