This particular install is a special, based on wheezy, but with a pinned

The only audio thing running, according to htop, is kmix. I do not see
any telltale footprints from PA in the htop listing.
This has been a PIMA here for a couple years,
surviving at least one
full fresh install to a new HD.
I hear a very strong thump during the bootup at about the time the
modules are loaded, which tells me the audio is alive and well.
However, when I have initially logged in and the system is ready to
be used for whatever my urges want to, if I want to hear the sound
on a web site as a news story is played, I must first call up a
terminal and issue:
alsactl restore
Now it seems to me there ought to be someplace in the junk that runs
after the login, to put a "/usr/sbin/alsactl restore", where it will
be executed as me, and this problem then should be fixed, at least
until a new install is done.
/etc/xdg/autostart/
or
~/.config/autostart/
Build a desktop file that has alsactl restore as it's command.
There will probably be examples in one of the above directories.
The question I have is what distro are you using that doesn't do this
on it's own already? (I am not sure what mine does to restore sound, I
just know it does)
It occures to me PA may be the thing that does this...
and removing PA
for proaudio work is common.
Likely, for a machine tool targeted OS, PA would be considered overkill.
The other 3 machines running this install are lucky if they even have a
$0.29 (USD) speaker in them to make beeps. Likely not even heard if the
machinery is running.
