N56VZ:低音炮不再工作

N56VZ:低音炮不再工作

我在华硕 N56VZ 上使用 Ubuntu 12.04,低音炮按照 Sami 建议的以下技巧工作:

a. 添加到 rc.local

echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs

echo 1 > /sys/class/sound/hwC0D0/reconfig

b. 在 /etc/modprobe.d/alsa-base.conf 中添加选项 snd-hda-intel model=asus-mode4

c. 重启

d. 在声音设置面板中将模式设置为“模拟环绕 5.1 输出”

但几周前,“模拟环绕 5.1 输出”框不再出现在声音设置面板上

我尝试安装此驱动程序:https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS 但没有结果。

这是我的 /etc/rc.local:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution  
# bits.
#
# By default this script does nothing.
fstrim -v /
fstrim -v /home
echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig

exit 0

和我的 /etc/modprobe.d/alsa-base.conf:

非常感谢你的帮助。

挂起后,计算机声卡停止工作。我可以使用耳机,但低音炮和计算机扬声器不工作,重新启动后就可以正常工作。有什么办法可以解决这个问题吗?如果不更改 /etc/modprobe.d/alsa-base.conf,低音炮不工作,但计算机扬声器在多次挂起后工作正常
