How to revert all changes made to sound settings?
While recording sound, there was too much noise and I changed some settings that I do not remember now and could not find the blog I used for instructions. The only thing I remember was removing pulseaudio and changing some sampling rates
Now I can almost use Audacity to record (it creates some humming only when talking) but I can at least record some sound.
The others: Skype, Google Voice or SFL Phone, I cannot use it at all. I can hear, but my voice is not delivered.
Is there any way to revert all changes I made (like a restore point or as a fallback: reinstalling kubuntu from scratch)
I changed nearly all settings with KMix and alfamixer, but it did not solve my problem.
Do you have any ideas?
