Hi Gary,

I have a multi-media application/system (built with Poky/Yocto of course)
that is currently using ALSA for the sound. This works great but now
I'd like to be able to share some of the sound resources, in particular
the audio output (speakers). To satisfy this, I looked at pulseaudio,
but I'm overwhelmed by the package choices (there are 120 packages),
not to mention what to do about configuration.
I don't see any examples (images, etc) that use pulseaudio.
Does anyone have any recommendations on what I might need to install,
how to configure it, etc, to take over from my simple ALSA setup?
The top tip is the PulseAudio documentation on the web site, that
lists all the plugins and what they do. The pulseaudio-server package
depends on all of the important plugins, so that gives you a working
PA setup once you've started it.
You might want to have a look at Guacamayo's use of PA, that uses it
and will automatically switch output when new speakers are plugged in
too. https://github.com/Guacamayo
Thanks, that helped. I've built Guacamayo for my RaspberryPi and
can see how it's set up.
That said, I've not had much luck actually getting anything out of the
audio :-( I tried the guacamayo-image-mex-raspberrypi.rpi-sdimg which
came up and gave me a nice display but it wasn't obvious how to import
media and/or make it play. I tried copying some files manually to the
SD card, but they wouldn't play either.
Then I tried guacamayo-image-audioplayer-raspberrypi.rpi-sdimg and it
was even less intuitive.
Can you give me some guidance? All I'd like to do is play a simple
(.wav) file on y RaspberryPi using pulseaudio.
Thanks
