I believe performance impact is very noticeable, especially I believe it would also be a latency impact.

The performance impact is hardly an issue on any modern machine you
will be running it.

The main concerns are regarding security.

While it's generally not recommended, you *can* run pulseaudio also as
a system-wide instance.

this is very well known to me, and also quite logical. pulseaudio is a
session process, espeakup is a system process. that whole thing actually
means it will have exactly those problems.

Howdy,
No one has any clue what is stopping it. People have contacted the pulse
developers who say it's something with espeakup, but then some think it
may
be speech-dispatcher's crappy pulse implimentation, which may be the
case,
cause I think it will work if a dekstop infironment isn't loaded with
orca.
No one has any clue how, or even what, to fix lol. So, I just avoid
pulse.
Thanks

Alsa itself has a pulseaudio plugin. So applications using alsa will
be routed through pulseaudio.

I tried to find the source for that plugin, but couldn't find it.
Maybe it was removed from alsa-plugins upstream? Or merged into
another plugin?

What is preventing speakup from using pulseaudio?

Howdy,
No, I don't have pulseaudio installed. I actually can't use it because
it
will not allow me to use speakup in the console. Interestingly enough,
I
read something that said moc doesn't have support for pulseaudio. So,
I
must
have found outdated info.
Still, I wonder if we are missing a plugin in alsa itself?
thanks

Are you using pulseaudio? This works out of the box for me with
pulseaudio. moc controls the volume of whatever was the default sink
when it was started.

Howdy,
I have installed extra/moc 1:2.5.0-3. Reading through the docs, and
things
on the net, I found a way to set up a softvol control for it in
alsa,
so
when I adjust its volume, it only changes the volume for moc.
Everything
went well, except, I can't adjust the volume from within the moc
app,
which
should be possible because you can set the alsa device and mixer in
the
~/.moc/config file.
It is using the right device, and amixer sset Mocmaster 50% sets the
volume.
It's just the in program controls that fail. When moc starts, it
gives
this
error:
ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared
library
/usr/lib/alsa-lib/libasound_module_ctl_softvol.so
This makes me think that either a plugin is missing from
alsa-plugins,
or
maybe moc is using an outdated way to change its volume. However, if
the
alsa controls are set to their defaults, the volume works fine, but
it
lowers the volume on the whole system.
I did a pacman search for alsa softvol but it didn't return
anything.
Is
there anything I can install to fix this?
Thanks for any help
