![怎样判断扬声器是否烧坏?](https://linux22.com/image/1140495/%E6%80%8E%E6%A0%B7%E5%88%A4%E6%96%AD%E6%89%AC%E5%A3%B0%E5%99%A8%E6%98%AF%E5%90%A6%E7%83%A7%E5%9D%8F%EF%BC%9F.png)
昨晚我正在戴着耳机听音乐,我的笔记本电脑突然关机了...我重新打开它,发现扬声器不再工作了,这是我已经尝试过的办法:用在 ask Ubuntu 上的旧帖子中的所有不同方式关闭脉冲音频,卸载 alsa 并清除所有内容,重新安装并重新启动,但什么也没发生..耳机音频工作正常,蓝牙音频工作正常,是扬声器突然停止工作了。

注意索引 2 上的线路端口模拟输出扬声器:扬声器(优先级 10000,延迟偏移 0 微秒,可用:否)属性:device.icon_name =“audio-speakers”活动端口:“
我猜那些是笔记本电脑的扬声器,但是当尝试时:
pacmd set-card-profile 2 analog-output-speaker
我得到:
No card found by this name or index.
这是一张图片来自脉冲音频控制。
等等等等…
我的问题是,如何知道是否是硬件坏了?因为我尝试使用 Kali live usb 驱动器,但声音也不起作用,所以我认为硬件问题已经解决了!!
所以这非常非常奇怪。因为我对扬声器坏了的想法很不满意,所以我从头开始重新安装了 Ubuntu 16.04,擦除了整个磁盘,发现了同样的问题,但我仍然不满意,所以我继续在 30GB 分区中安装 Windows 7,猜猜“它们能用”... 是的,让我重复一遍,出于某种原因,扬声器在 Linux 上不能用,但在 Windows 上可以,这让我很高兴,因为它们没有坏。所以我最好的猜测是,找出扬声器是否坏了的最好方法是安装 Windows,看看它们是否仍然不能在那里工作。
另一方面,我安装了一个全新的系统,没有扬声器声音,是否可以确定要提出另一个问题?
答案1
经过一个月的尝试、乱七八糟的事情、删除操作系统、重新安装并重新尝试;我找到了问题的解决方案:我在 Synaptic 中安装了 alsa-tools 和 alsa-tools-gui,安装后的几个应用程序中有一个调用 HDAjackRetask,在那里我将两个耳机选项覆盖为“未连接”和“安装覆盖机器人”*(这使它永久生效,重新启动,Speackers 就可以工作了!现在。我不明白这个功能是如何工作的..它是如何影响耳机插孔的,或者只是发布我如何修复它!!!...
