T60 声卡的问题

pangwa

大家好，

貌似我的机器的声卡驱动没有正确配置， 请问能帮忙看一下吗？ 机器 是IBM T60, 我用的是pulse， 但是在pulse的设备管理器里只能看到一个默认的dummy 输出设备

下面是相关的信息
:~$ lspci |grep -i audio

看来是一个bug, pulse的问题，
今天试了alsa， 发现alsa工作， 再找了一圈在这里https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/394500
找到了解决方法



I think I've found a temporary workaround (not a solution).

I've opened /etc/pulse/default.pa and commented 4 lines.

Before:

### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect
.else
### Alternatively use the static hardware detection module (for systems that
### lack udev support)
load-module module-detect
.endif

After:

### Automatically load driver modules depending on the hardware available
#.ifexists module-udev-detect.so
#load-module module-udev-detect
#.else
### Alternatively use the static hardware detection module (for systems that
### lack udev support)
load-module module-detect
#.endif

Then I killed/restated pulseaudio and now I have audio input/output from the internal audio device.

Still, the Hardware tab under Sound Preferences is empty, as if there was no audio device available.

Sound Preferences > Hardware > Choose a device to configure: > (empty field)
