Ubuntu 20.04.6 LTS下HP Omen笔记本主扬声器间歇性音频中断问题求助

大家好，我遇到了一个困扰很久的音频问题，想请各位帮忙排查下：

• 环境：Ubuntu 20.04.6 LTS系统，HP Omen笔记本
• 核心症状：主扬声器在从「无音频播放」切换到「有音频播放」的短时间内，会出现约1秒的音频中断；但持续播放音频（比如连续播放YouTube视频）时完全正常
• 影响范围：这个问题在所有应用（VLC、Chrome、Firefox、系统声音测试）和所有音频源（音乐、视频通话、视频）中都存在，但仅主扬声器受影响——目前测试蓝牙耳机和有线耳机都正常（不过之前蓝牙耳机也出现过相同问题，但现在无法复现）
• 已尝试方案：我试过某篇帖子里的所有解决方案，以及该帖子描述中链接的其他帖子方法，但都没能解决问题

以下是我在VLC中暂停再恢复播放时捕获的调试日志：

另外，播放VLC期间dmesg没有相关问题输出，只有审计类消息。
