LG gram 2023 (i7-1360P) 扬声器没有声音

刚买了一台 LG Gram 16Z90R-G.AD78F EVO，这是全新的 Lg Gram，配备了新的 i7-1360P，而不是之前的 i7-1260P（我之前的笔记本电脑，没有声音问题）。

安装 Ubuntu cinnamon 23.04 后，一切都运行良好，除了扬声器发不出任何声音，它在 HDMI 输出或插孔上运行良好，但切换到内置扬声器时不会输出任何声音。

我尝试过网上很多教程，比如这个一

问题解决了，请看一下：

https://forums.fedoraforum.org/showthread.php?331130-Fixing-ALC298-audio-（扬声器无声音）

该解决方案依赖于执行许多hda-verb（来自alsa-tools）命令来重新配置高清音频编解码器。

sudo apt install -y alsa-tools
wget https://github.com/joshuagrisham/galaxy-book2-pro-linux/raw/main/sound/necessary-verbs.sh

chmod +x necessary-verbs.sh
sudo ./necessary-verbs.sh

如果它对你有用，你可能希望在启动时像这样运行它：

cat <<EOF | sudo tee /etc/systemd/system/audio-fix-alc298.service
[Unit]
Description=Run internal speaker fix script at startup
After=getty.target

[Service]
Type=simple
ExecStart=/usr/local/sbin/necessary-verbs.sh
TimeoutStartSec=0

[Install]
WantedBy=default.target
EOF

笔记：

  • hda-verb 在 Ubuntu 22.04 上至少需要 root 权限
  • 像往常一样，你应该检查不受信任的 shell 脚本
