![Linux下没有声音](https://linux22.com/image/57110/Linux%E4%B8%8B%E6%B2%A1%E6%9C%89%E5%A3%B0%E9%9F%B3.png)
我的系统上没有声音(opensuse 13.1 | gnome 3.12)。
alsamixer
ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL default
cannot open mixer: No existe el fichero o el directorio
一些需要补充的数据:
sudo /sbin/lspci | grep Audio
00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Wrestler HDMI Audio
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) (rev 40)
cat /proc/asound/cards
0 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xf0444000 irq 41
1 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xf0440000 irq 16
Gnome 看不到卡片:(
aplay -l
**** List of PLAYBACK Hardware Devices ****
ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL hw:0
aplay: device_list:277: control open (0): No existe el fichero o el directorio
ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL hw:1
aplay: device_list:277: control open (1): No existe el fichero o el directori
那么我怎样才能让它发挥作用呢?

这几天也遇到类似的问题。
安装pulseaudio
并pavucontrol
为我解决了问题。安装后,您必须运行 pavucontrol 并配置您的声卡一次。
