I have recently installed Xubuntu 20.04 LTS and I noticed something strange. I do have sound and it works well, but I don't have any indicator of volume in the panel.
I tried using alsamixer to change it, but there I see that all the channels are set to 0 and there isn't any volume on any of them:
This is a really odd problem and to be honest I have no idea how to troubleshoot it. Hope that someone could help me.
