I do agree that coding for pulse can be a steep learning curve, which
is why I opted to build all my solutions by simply connecting to the
text mode control socket and sending commands/parsing text output. I
have built what is essentially a multiplex audio switch allowing any of
x number input sources to play out of any x number of output sinks, all
controlled via a python or php app.<br>
<br>
You should check out module-combine-sink. You could combine all your
outputs, then simply mute all but the one you currently want to use. I
am using this as a 4x4 switch for audio and it works great.<br>
<br>
I also have simple (but poorly commented) python/php source I am happy
to share if it helps.<br>

say this list is pretty unresponsive in helping the community so I have
to ask myself "is pulse is a sensible choice for audio development
today"? Particularly since there is little in the way of useful setup
documentation for actually using the library on a programatic way, the
error messages from the library and utilities are not particularly
helpful and so on.

<div>What I need to be able to do is route audio around. I suspect
write a module for pulse that will look at the alsa stream class and
based on that use the input index to set the sick for that stream. It
would be nice to have a feature whereby I can rout all output sent to a
particular sink, to another sink. I guess what I'd like to do is be
able to create virtual devices whose output can be changed on the fly.
So for example I could define an mp3 output that I can switch between
headphone output and speaker output depending on a system setting. Or
between one speaker output and another. If pulse has a means to do
this already I'd appreciate someone pointing me in the direction that
can help.</div>
<div><br>
</div>
<div>It seems ALSA will do most of this and the ALSA list seems to be
a lot more active, so maybe I was mistaken in thinking that Pulse would
really be a useful addition to our audio stack, particularly since on
an embedded system it consume disproportionate resources for the
benefit it provides.</div>
<div><br>
</div>
<div>Also where is the mixer implemented and how is it controlled.
Or is the mixer just a dumb "you have 3 streams coming in and I will
make them one" type deal. In other words is there bussing or output
switching in the mixer. If not, is this planned?<br>
<div><br>
</div>
<div>Anyway, in case this helps anyone else, the sources that are
listed by list-sources are not really sources to pulse. So trying to
move them around will not work. Here's something I wrote up on the
subject:</div>

familiar with pacmd. According to the help, this looks as if it should

<div><font class="Apple-style-span" face="Verdana">Eventually I
want to publish several virtual devices, route them to a mixer
(possibly via an SRC) and route the mixer output to a specific ALSA
sink. I need two instances of mixers so that I can mix some streams to
one output device and some streams to another. I need to be able
to dynamically rout the entire output to another ALSA sink depending on
the policy set. I'd also like to rout sources to the different mixer
instances as required. If I can do routing within a single mixer
instance, so much the better. Is Pulse capable of this or do I need to
find another route to implement this.</font></div>
