XMG Pro 17双系统Ubuntu 23.04无声音问题求助（扬声器、耳机均无输出）

大家好，我刚入手一台XMG Pro 17笔记本，装了Windows 11和Ubuntu 23.04 STS双系统。Windows下音频一切正常，但Ubuntu里不管是内置扬声器还是插耳机，都完全听不到声音。

在系统设置里选择内置音频设备时，音量条明明在跳动，系统也显示正在输出音频，但就是没有任何声音。我试过切换耳机输出、甚至用HDMI接口输出音频，结果都一样。另外我已经重新安装过alsa和pulseaudio，但问题依然存在。

我运行了lspci -v | grep -A7 -i "audio"命令，得到以下音频设备信息：

运行pacmd list-cards命令的输出如下：

我能想到的排查方法都试过了，实在找不到解决思路，有没有大佬能给点建议？万分感谢！
