ALSA pcm.c:8526:(snd_pcm_recover)出现运行不足

Question

在开始了解音频R包和其他基于该软件包的包时，我遇到了两个问题：

• 声音很可怕，不能被
• 理解，我的控制台充满了消息

一开始我收到这样的信息：

ALSA lib pcm_dsnoop.c:641:(snd_pcm_dsnoop_open) unable to open slave
ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave
ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side

ALSA lib pcm_usb_stream.c:486:(_snd_pcm_usb_stream_open) Invalid type for card
ALSA lib pcm_usb_stream.c:486:(_snd_pcm_usb_stream_open) Invalid type for card
ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slaveALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred

在尝试并搜索错误之后，我设法删除了其中的大多数错误，目前我只得到了这些错误(编辑，我仍然收到第一条消息，它们变得非常罕见:/)：

ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred

错误行的数目是随机的，有时没有错误，有时是一串。

我使用了带有简单play(sin(1:10000/20))代码的音频包和带有以下内容的Rmusic pakage：play_music(c("B5","A5","G5","F#5","E5","D5","C#5","B4"),c(1,1,1,1,1,1,1,1))

两个人都犯了同样的错误

我在kubuntu 20.04上安装了最新的R基3.6.3

> audio.drivers()
       name      description current
1 portaudio PortAudio driver    TRUE

在开始测试之前安装了Portaudio19 19-dev。

Answer 1

我的"silero“文本与speech python框架也有类似的问题：

ALSA lib pcm.c:8545:(snd_pcm_recover) underrun occurred silero

我通过从“软件”-application安装建议的编解码器来修正它。

加载项->编解码器-> GStreamer多媒体编解码器->安装

我也安装了所有建议的编解码器，并重新启动。对我来说，错误已经消失了。吉尔！
