我正在运行一台运行 Ubuntu 21.10 和内核 5.13.0-19 的 Dell Inspiron 17-7779。根据 BIOS，它有一个 RealTek ALC-3253 音频芯片，运行 lspci 会给出此响应
00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)
音频通过内置扬声器正常播放，但当我插入耳机时，没有音频。根据 PulseAudio Volume Mixer，声音在频道上播放，但耳机中没有声音
偶尔，它会工作，我估计大约每启动笔记本电脑五次就会工作一次，但在运行时经常会停止工作。
我尝试从 PulseAudio 切换到 PipeWire，但没有成功 patcl info

它是一台双启动机器，同一个耳机可以在 Windows 和其他设备上使用。
我注意到，有时当我打开 Audacity 时，某些选项无法播放。有时没有“默认”选项，只有“hdmi”
