由于我的 HP 超级本的触控板需要更换，因此我购买了一台便宜的 198 美元 Acer Gateway NE46RS1 笔记本电脑并在其上安装了 Linux Mint 18。除了耳机输出之外，这款笔记本电脑只有一个集成扬声器。
所以，我发现在 alsamixer 中，它需要增加“耳机”音量才能从笔记本电脑扬声器中听到声音。另外，如果我插入耳机，扬声器就会静音并且保持静音，除非我再次提高耳机音量。如果我想让扬声器正常工作，必须调高混音器中的耳机音量。我尝试通过运行“sudo alsactl store”来保存 alsa 状态，该状态在下次重新启动时不会保留并被静音。另外，请注意“前”卷丢失了。
我想要的是为扬声器重新分配适当的音量控制选项，而不是使用“耳机”音量，以及保存音量状态，而不是在每次启动时自动静音。
请参阅 alsamixer 控件和 alsa-info.sh 详细信息： Alsa-Info 结果
