[Slackbuilds-users] TiMidity++ as daemon, failure to connect to pulseaudio
porting at use.startmail.com

The instructions provided in TiMidity++'s Slackbuild page for running
it as a daemon/alsa sequencer don't work.
rc.timidity will have the daemon started, but it will fail to generate
any sound output.
I suspect that, when I start a desktop session, a pulseaudio instance
under the privileges of my user gets started. TiMidity++, running as a
root daemon, is not authorized to inject sound into Pulseaudio because
it is a different user than my desktop one.
Could somebody else reproduce this problem and confirm it?
A possible solution would be to run pulseaudio as a system wide daemon,
but that is too problematic.
Another possible solution would be to apply something like this:
My suggestion, if this issue is reproducible and shown to be caused for
the above reasons, is to update the slackbuild in the following ways:
1- Recommend the creation of a timidity user for running as a daemon.
Running the daemon as root is a bit dangerous.
2- Modify rc.timidity for starting the daemon under the privileges of
3- Recommend the solution posted in the Arch wiki. I have yet to try it,
and is also a bit dangerous because it allows system-wide access to the
daemon run by the user to everybody in the system, unless you take
additional messures (such as changing the permissions of the socket?)
Trivial solution is to start timidity with the desktop session, running
with the privileges of the user sitting in front of the machine.
