从 Windows 10 重新启动后，Ubuntu 18.04 中没有声音

Question

我在华硕 Zenbook 笔记本电脑上使用 18.04，关机后我的声音工作正常（干净的平板）。如果我启动进入 ubuntu，声音有效，如果我仍然重启进入 ubuntu，声音仍然有效。如果我启动到 Windows 10，然后关闭并启动到 ubuntu，声音工作。但是，如果我启动到 Windows 10 然后重新启动到 ubuntu，现在声音不起作用（没有静音，alsamixer但根本没有声音）。只有关机修复它，重新启动不会。我已经按照所有其他答案中的建议禁用了 Windows 中的快速启动并杀死/清除了脉冲音频。声音也不适用于耳机

我在声音有效和无效时拍摄了两个系统日志快照，我看不出它们之间有任何显着差异。在我看来，它确实像硬件/固件问题，但我想必须有一种方法可以从软件中修复它。有什么建议？

这最终成为 Realtek ALC294 alsa 驱动程序中的一个错误。它已经在启动板中报告：https : //bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1742852
