检测到声音硬件,但键盘按钮、面板图标按钮不起作用

我有 64 位 Ubuntu 11.10。声音工作正常,但键盘声音键不起作用。顶部面板上的声音图标也不起作用。此外,声音设置中没有显示任何硬件设备和正在运行的应用程序。

一些可能有帮助的命令的结果:

$ lspci -v | grep -A7 -i "audio"

我认为缺少了一些包。有什么建议吗?

这是我尝试过的... 1. rm -rvf ~/.pulse/

重启

没有成功

  1. https://help.ubuntu.com/community/SoundTroubleshootingProcedure

运行此命令 sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image- uname -rlibasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image- uname -rlibasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aGcat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g' whoami

因为我有 11.10

重启

猜猜看...它像以前一样工作:)

卡马尔

我的声卡也遇到了同样的问题。但是根本没有声音。系统是 32 位 Ubuntu 11.04,带有 gnome-shell 3.3.2。

$ lspci -v | grep -A7 -i "audio"
Audio device: nVidia Corporation MCP55 High Definition Audio (rev a2)
    Subsystem: Micro-Star International Co., Ltd. Device 7250
    Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 20
    Memory at fbef0000 (32-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: HDA Intel
    Kernel modules: snd-hda-intel

$ cat /proc/asound/cards 
 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfbef0000 irq 20

输入$ sudo alsa reload设备后,声音设置中会出现,但仍然没有声音。
