Installed manjaro yesterday and there is no sound

To further complicate your life; a little housekeeping…

Hi @OddToast and welcome to the Manjaro community.

As a new user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit. To that end, some or all these links will be invaluable:

And last, but not least, the Stable Update Announcements, which you should check frequently for important update related information. Occasionally an issue might be directly related to a particular update; it’s always best to check those announcements.

I hope this helps. Cheers.
