esd prevents sound working in some apps/games...

is there a workaround apart from manually killing the esd
process? I'm
using dapper, latest updates.

AFAIK, ESD opens the sound device, so if any other
application, like
MPlayer or a game tries opening the device directly, it will
fail. I
think ESD has a feature to automatically closed the sound
device after
some period of inactivity.

Of course, the only solutions I see are:

1. Disable ESD or killing it.
2. Configuring ESD to release the sound device after some
period of idle time.
3. Configure the game to use ESD.
4. Everybody using ALSA, which supports hardware/software
sound mixing
which allows several different applications to output sound
at the
same time.

This has been done for both Breezy (5.10) and Dapper (6.06.1
LTS); cf.
/etc/esound/esd.conf .

If the game is SDL-based, one could (re)install
libsdl1.2debian-esd. The
recommended route is to use libsdl1.2debian-alsa (which is
installed)
instead.

Mostly. OSS-only applications (notably Adobe Flash) will
need
hackarounds like esd or aoss.

So what's the real point of ESD? What does it do? Even if I
kill it's
process I can still get sound from my applications... so why
run it?

Also I can't seem to adjust it's idle time-out from
system-preferences-sound

so why run it?

AFAIK, ESD was used a long time ago when the sound drivers
didn't
support native sound mixing. I think now it seems pretty
useless to
me. aRTS, for example, is similar to ESD but has several
plug-ins to
implement fancy effects, like echo, filters, etc.
