我有 VIZIO CT15-A5,12.04 LTS (64) 运行顺畅...只有一个问题...由于缺少麦克风输入,我无法录音或使用 Skype。
我尝试使用 alsa 混音器调高音量,并尝试使用脉冲音频音量控制,但似乎存在硬件问题...它在 Windows(双启动系统)下运行良好
以下是输出lspci -vv

我还尝试将以下内容添加到“/etc/modprobe.d/alsa-base.conf”,但无济于事:
options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes
是的,我甚至尝试了奇怪的前右声道禁用,但无济于事。
这是我的原始 alsa-base.conf 的副本

答案1
我在同一台笔记本电脑上遇到了完全相同的问题,并且几乎尝试了所有我能找到的针对此类问题的标准修复方法。所以我只想在这里评论一下,安装这个版本的 alsa为我解决了这个问题。我假设这意味着它将很快被纳入标准存储库,但以防万一有人仍然需要它。
