过去几天，我一直在尝试自己解决音频问题，但没有成功。我有一台 HP Evy 32 AIO 双启动（禁用快速启动），配有 ALC 274 声卡。扬声器和耳机不工作，但蓝牙可以工作。我尝试了不同发行版的故障排除步骤，包括 Ubuntu、Linux Mint、Fedora、Manjaro 和 Pop_os。我是 Linux 新手，所以请多多包涵。
我尝试过的方法的链接： https://support.system76.com/articles/audio/ https://bbs.archlinux.org/viewtopic.php?id=276789 https://forums.linuxmint.com/viewtopic.php?t=363010 https://forums.linuxmint.com/viewtopic.php?t=329074 https://github.com/thesofproject/sof
我不太确定我是否正确安装了 sof 固件，但是我使用了带有符号链接方法的 rsync，因为我无法让脚本正常工作。

-我唯一没有真正弄乱的是 hdajackretask，但我已经运行了 RtHDDump.exe 进行比较，一切看起来都很好。
-我唯一的成功就是跑步
sudo tee /etc/modprobe.d/alsa-fix.conf <<<'options snd-intel-dspcfg dsp_driver=3'
这给了我我的软件驱动程序
-运行 Windows VM 并在 VM 中安装 Realtek 驱动程序。这确实给了我声音。
-另外，我不知道这是否有帮助，但我在蓝牙中有一个“HP Envy Speaker”选项。当我连接到它时，它所做的就是尝试将扬声器用作麦克风。
-我还应该指出，我有 Nvidia Optimus。我确实禁用了它，并尝试了一些方法，但没有成功。
-如果您还有什么需要，请随时提出。我目前正在全新安装 Ubuntu，以防有人想回到基础阶段。
