描述:Ubuntu 21.10 / 代号:impish
如果重要,运行 LXDE
我在我的外部 USB 扬声器上观看 youtube,声音播放得很好。
突然间,它们静音了,插入的耳机(Plantronics,Inc. DA40 适配器)在没有我干预的情况下播放声音......
我确实在切换时通过 journalctl 看到了一些日志:
Mar 01 10:04:57 wilddog pulseaudio[1678]: ALSA woke us up to write new data to the device, but there was actually nothing to write.
Mar 01 10:04:57 wilddog pulseaudio[1678]: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers.
Mar 01 10:04:57 wilddog pulseaudio[1678]: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
这是一个非常新鲜的安装。
如何在外部扬声器上保持稳定?
原来是一个坏的usb扬声器。
