我试图在python中使用socket和pyaudio编写一个语音聊天的代码。我写了它，它可以工作，但它产生了以下的错误
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open)无法打开奴隶。
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) 未知PCM卡.pcm.area
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) 发现没有匹配的通道图。
ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open)无法打开奴隶。
并不断提出这个问题。
ALSA lib pcm.c:8306:(snd_pcm_recover)发生欠运行"
我在接收和播放声音的Server.py中得到这些。如何解决这个问题？
