耳机里有噼啪声

我最近在新的 Asus BX425EA 上安装了 Ubuntu 20.04（与 Windows 双启动）。到目前为止，一切顺利，一切似乎都运行良好。除了当我使用耳机时，我会听到噼啪声。此外，如果音量较低，我会受到干扰。

使用笔记本电脑内置扬声器，没有问题。此外，我尝试使用另一个蓝牙连接的耳机（不是我的，我借的），没有问题。我的耳机没有蓝牙，我只能用电线连接。但问题是，笔记本电脑没有 3.5 毫米音频插孔插头：有一个 USB-C 转插孔适配器（笔记本电脑随附，见图片）。所以，我很确定问题出在这个适配器上。

我已经尝试了很多方法，但都没有成功：

以下是一些信息：

$ cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC294
Codec: Intel Tigerlake HDMI

和：

$ dmesg | grep usb

任何帮助将不胜感激！

答案1

经过几天的尝试，我还是没有成功，于是我冒险购买了 Apple USB-C 转 3.5 毫米接口适配器（法国 Apple Store 售价 10 欧元）。在这篇文章中，我有点希望它能起作用。我想我很幸运，因为声音非常清晰！即插即用，无需配置。
