运行 Ubuntu 22.04.2，由于内核 5.19.0-35，HDMI 音频输出存在问题。您能帮我恢复我的 HDMI 音频输出吗？
使用内核 5.19.0-32 时，发现 HDMI 输出：
$ uname -a
xxx 5.19.0-32-generic #33~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Jan 30 17:03:34 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
cat /proc/asound/cards

HDA Intel PCH at 0xa0340000 irq 127
1 [HDMI ]: HDA-Intel - HDA ATI HDMI

使用内核 5.19.0-35 时，找不到 HDMI 输出：

答案1
简单地说，我删除了相关的内核并恢复到之前的内核。
sudo apt --purge remove linux-headers-5.19.0-35 linux-headers-5.19.0-35-generic linux-image-5.19.0-35-generic linux-modules-5.19.0-35-generic
