我无法录音，我正在检查我的麦克风。

在另一边：
[joseluisbz@centos ~]$ cat /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=pch position_fix=1
[joseluisbz@centos ~]$
现在检查一下alsamixer
我明白了。
如您所见：我的卡中有：PulseAudio
改变与F6.
并选择F5以查看所有设置。
但是，退出时更改不会保存。并且选定的声卡不会被保留。
现在，我想使用sudo alsamixer.
[joseluisbz@centos ~]$ sudo alsamixer
[sudo] password for joseluisbz:
No protocol specified
xcb_connection_has_error() returned true
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
cannot open mixer: Connection refused
[joseluisbz@centos ~]$
稍后，进行更改后：
[joseluisbz@centos ~]$ alsamixer
[joseluisbz@centos ~]$ alsactl store
alsactl: state_lock:125: file /var/lib/alsa/asound.state lock error: File exists
[joseluisbz@centos ~]$

我该如何解决这个问题？
