Ubuntu 23.04 突发无声音问题求助（双系统环境）

系统与硬件信息 #

• 双系统配置：Ubuntu 23.04 + Windows 11（分独立磁盘安装）
• 设备：HP OMEN 游戏台式机
• Ubuntu桌面环境：已升级到最新版本的Cinnamon

问题背景 #

这套双系统我已经稳定使用了好几个月，之前声音一直完全正常，但上次启动Ubuntu后突然没声音了。我每次进Ubuntu都会执行系统更新升级操作，Windows 11的声音完全正常，Ubuntu这边我已经检查了静音开关、音量滑块这些基础设置，都没有问题。

声音设置里显示输出设备是「Line Out Built-in Audio」，配置文件为「Analog Stereo」，之前能正常工作的测试音现在完全没输出，系统提示音也彻底消失了。我搜了很多解决方案尝试都没用，作为Linux新手我平时根本不敢乱改系统设置，最近也没安装新程序，实在卡壳了，求大家帮忙！

已执行的排查操作及测试结果 #

我按照网上的建议跑了一些命令，结果如下（我完全看不懂这些输出代表什么）：

后续尝试的操作 #

• 安装了ALSA Mixer，调整了各种参数后只能听到非常微弱的声音，完全达不到可用程度
• 执行了pulseaudio --kill和pulseaudio --start命令，没有任何改善
• 我完全不知道怎么重新安装音频驱动，网上找到的都是针对旧版Ubuntu的教程，不敢随便尝试

真的很沮丧，明明之前一切正常，我什么也没改就突然出问题了，Windows那边又完全没问题，希望有人能帮我解决这个问题！
