upgrade 14.2>15.0: No sound except when root
by harryhaller from LinuxQuestions.org on (#6HWEK)
Just upgraded to 15.0 and cannot get any sound neither in browser nor when using mplayer.
Alsamixer doesn't show any card when I press F6:
Code:(default)nor does pavucontrol.
It shows "dummy output"
and under "Advanced", PCM is shaded and can't be clicked...
But as root alsamixer [F6] shows me two cards
Code:default:0 HDA Intel PCH
default:1 HDA NVidiaand I have sound when I use mplayer.
So I suppose it's to do with permissions.
Changes and hints mentions new groups, but I don't understand how they are to be used - or to what they apply - I don't know what these services are:
Code:*** NEW USERS/GROUPS SINCE 14.2 ***
cgred group, GID 41
dovecot user and group, UID and GID 94
dovenull user and group, UID and GID 95
icecc user and group, UID and GID 49
ldap user and group, UID and GID 330
ntp user and group, UID and GID 44
postfix user and group, UID and GID 91
postdrop group, GID 92To sum up, I get sound as root, but not otherwise.
