[gentoo-user] systemd and amixer

[gentoo-user] systemd and amixer

[covici]

Hi.  Since I booted into systemd, if I try to run amixer from a normal
user I get very different results than if I run amixer as root.  The
directory /dev/snd  is  world rw and I would like to know what is
happening.  The numbers are very different for instance the Master
volume as a regular user is 100%, but as root  its 40% where it should
be.

Thanks in advance for any  suggestions.

  Is /var/lib/alsa/asound.state world readable?  If not, regular users
may get some default value.  On my system...

[d531][waltdnes][~] ll /var/lib/alsa/asound.state
-rw-r--r-- 1 root root 7749 May 28 17:32 /var/lib/alsa/asound.state

Yep, its the same, but when I tried to restore as a regular user (which
I normally don't do) it complained about the .lock file and restored to
some strange values which involved so much feedback that I had to go to
a root window and restore again.  The strange thing is that I had no
problems like this under openrc, so I wonder what systemd is doing and
how I can get around it.

  The settings are supposed to be automatically restored as part of the
bootup process.  If you run openrc, did you execute...

rc-update add alsasound boot

...at alsa installation as per http://wiki.gentoo.org/wiki/ALSA ?  If
you run systemd, I assume there's an equivalant service file.  And,
grasping at straws, is your regular user a member of the "audio" group?

alsa-utils brings alsa-store.service and alsa-restore.service, but these
should be enabled by default

$ find /usr/lib/systemd/ -name *alsa*
/usr/lib/systemd/system/basic.target.wants/alsa-restore.service
/usr/lib/systemd/system/basic.target.wants/alsa-state.service
/usr/lib/systemd/system/shutdown.target.wants/alsa-store.service
/usr/lib/systemd/system/alsa-restore.service
/usr/lib/systemd/system/alsa-state.service
/usr/lib/systemd/system/alsa-store.service

The restore does work under systemd, but its done as root.  Also its
done under openrc as well.  Under openrc, the regular user will get the
same contents using amixer get Master as root, whereas under systemd he
will not.  I was told to take the user out of the audio group some time
ago and so I did, with no result I know of, maybe I will put it back and
see if it makes any changes.
