Ever since I upgraded to Ubuntu 20.04.4 LTS, I've had to run sudo alsa force-reload after rebooting or else I'll have no sound. However, after a recent system update, even this stopped working. Now when I run the command, I get the following output, and then the command hangs:

Unloading ALSA sound driver modules: snd-hrtimer snd-hda-codec-realtek snd-hda-codec-generic snd-hda-codec-hdmi snd-soc-core snd-compress snd-pcm-dmaengine snd-hda-intel snd-intel-dspcfg snd-hda-codec snd-hda-core snd-hwdep snd-pcm snd-seq snd-seq-device snd-timer (failed: modules still loaded: snd-hrtimer snd-hda-codec-realtek snd-hda-codec-generic snd-hda-codec-hdmi snd-soc-core snd-compress snd-pcm-dmaengine snd-hda-intel snd-intel-dspcfg snd-hda-codec snd-hda-core snd-hwdep snd-pcm snd-seq snd-seq-device snd-timer).

I'm not sure why the modules are failing to be unloaded now.

The same happened to me. I found the solution here.

The sound was restored after running on terminal

systemctl disable timidity

Apparently, it is not a problem of ALSA itself, but this timidity converter. (well, with such a name...)
