播放声音卡顿
安装完Ubuntu18.04后，用网易云音乐听歌时，声音总是每隔几秒卡顿一下，特此记录一下解决方法。
用命令sudo lspci -v | grep -A7 Audio查看系统的使用的声卡设备是Intel Corporation 200 Series PCH HD Audio，使用的驱动时snd_hda_intel。
~ sudo lspci -v | grep -A7 Audio

有时电脑重启后，声音就一直每隔几秒爆音一下，重启也没用。可以执行一下命令，重启一下pulseaudio。
pulseaudio --kill \
&& rm -r ~/.config/pulse/* \
&& pulseaudio --start
