How to recover ALSA default configuration after reverting changes in .asoundrc? I've done some changes via `.asoundrc` (created "softvol" volume controls). Now, I want to get rid of these changes. Nothing of the following helped so far: * Deleted `.asoundrc` and rebooted system. * Created empty `.asoundrc` * `alsactl` commands (`restore`, `init`, ...) * Temporarily removed `/var/lib/alsa/asound.state` * ... **Any ideas on how to get back to the original config and have the volume controls I added vanish from`alsamixer`?**

The `softvol` controls are stored in memory together with other data related to the actual sound card, and are saved to and restored from `/var/lib/alsa/asound.state` when the machine is shutting down or booting.

So to remove them, you have to

1. unload the sound driver module (`rmmod snd-hda-intel`, or whatever you're using), and then
2. remove the entry from `/var/lib/alsa/asound.state` (or the entire file).
