Lubuntu 11.10 中耳机无法使用

问题没有解决，但我又回到了11.04

1.问题描述

扬声器可以正常工作。当我插入耳机（尝试了 2 种类型）时，扬声器和耳机都静音了。

==============================================================

2. 我找到了这个。我如何在 Lubuntu 上尝试这个？

“我需要做的就是将声音设置屏幕的硬件选项卡上的配置文件从‘模拟立体声双工’更改为‘模拟立体声输出’。”关联

=============================================================

3. 已经尝试过

（我）[HP Pavilion dv6、IDT 92HD75B3] 线路输出不会使内置扬声器静音

没有用。

（二）HdaIntelSound如何

$cat /proc/asound/card0/codec* | grep Codec
Codec: Conexant CX20549 (Venice)

$给了我一个文件，但是对于 conexant ，sudo gnome-open /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz
只有Conexant 5045，，，。Conexant 5047Conexant 5051Conexant 5066

（三）[Bug 876020] 回复：[8932CTO，Conexant CX20549（Venice），绿色耳机输出，左] 完全没有声音（注意：我需要重新启动。）

(i) 现在，当我插入耳机时，声音会从扬声器和耳机中发出。

（二）自动静音选项alsamixer已经消失了。

Fn+F10/F11(iii) 我无法再改变音量。

=============================================================

答案1

我不知道这是否会起作用，但我以前在不同的硬件上确实如此。您可以尝试编辑 /etc/modprobe.d/alsa-base.conf 文件，在文件末尾添加以下内容

options snd-hda-intel position-fix=1

然后，重新启动您的机器并检查它是否正常工作。
