Ubuntu 10.04下耳机不工作的解决办法(ACL269声卡)
主旨:
升级alsa到1.0.23版。
注意事项:
(1)编译alsa所依赖的包:
ncurses-dev gettext xmlto libasound2-dev linux-headers libncursesw5-dev
(2)需要编译的包:
alsa-driver-1.0.23
alsa-lib-1.0.23
alsa-utils-1.0.23
(3)编译之前需要先停掉alsa
sudo /sbin/alsa-utils stop
(4)编译安装完之后再运行:
sudo alsaconf
(5)如果需要在外置音箱与耳机之间自动切换,还需在/etc/modprobe.d/alsa-base.conf里添加:
options snd-hda-intel model=auto
