Greetings, still hunting down the reasons for my laptop not producing any sound, I have meanwhile found reports on the web "no sound even though root is in group audio" or "Dbus doesn't "care" who root is -- it checks the ident- ity of the account that requested an action, and if that account isn't allowed to perform that action, the request is denied" [1].
I can't remember ever having manually added user "root" to any groups since I installed Gentoo on my laptop (as opposed to adding my own user- id to quite some groups)m and these are the few groups "root" is into: $ id root uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),26(tape),27(video) $ Should there be more? In particular, should "root" be in group "audio"? Sincerely, Rainer [1] https://www.linuxquestions.org/questions/showthread.php?p=3640443#post3640443
