    现象：社区版20.3的时候HDMI输出图像和声音都是正常的，升级到社区版20.5后，笔记本电脑合上盖子之后HDMI就没图像输出，但声音输出是正常的。升级到社区版20.6之后HDMI输出图像是正常的，但没有声音输出了。

    比较奇怪的是我记得原来声音输出设备里HDMI显示的设备名称应该是HDMI1 Output(HD-Audio Generic)，升级到20.6后变成了HDMI2 Output(HD-Audio Generic)，设备名变了是不是因为驱动变过呢？

    因为看到inxi -F的输出了里显示声卡驱动列出了两个驱动：

    Audio:     Device-1: Advanced Micro Devices [AMD/ATI] driver: snd_hda_intel
Device-2: Advanced Micro Devices [AMD] Raven/Raven2/FireFlight/Renoir Audio Processor driver: snd_rn_pci_acp3x
Device-3: Advanced Micro Devices [AMD] Family 17h HD Audio driver: snd_hda_intel

    虽然之前HDMI正常有声音的时候没注意过驱动列出是啥样的，但针对这两个驱动在某不知名搜索引擎上搜索snd_hda_intel snd_rn_pci_acp3x，看到也有人有类似的问题：https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1901157。

    参考帖子里一个回答的做法，按顺序执行了以下命令后，HDMI就重新输出有声音了：

    sudo modprobe -r snd_rn_pci_acp3x
systemctl --user restart pulseaudio
sudo modprobe snd_rn_pci_acp3x

    原理没有搞明白，感觉像重新加载了一次驱动，中间把pulseaudio这个服务重启了一下。而且帖子里是把几条命令弄成了脚本每次电脑启动自己执行一次，但我没弄成脚本执行，重启笔记本HDMI依然会有声音输出。

    记录一下，希望能够帮助到和我遇到相同问题的人。
