The pi doesn't have a very good sound chip in it. It is only capable of
stero at 48KHZ. It can't do surround sound, and all the tests I've done
on it seem to indicate even front/rear speakers make no difference,
there's only left/right on the pi.
I did go hunting for sound cards that will work on the pi, and have found
3 of them, though detailed specs on the various cards were not available,
so I have yet to determine of any of those usb sound cards could be used
to render full audio required for the kinds of games the vi community
would like to see. I'm going to purchase one of the cards in a couple
weeks, and begin experimenting. Hopefully I can find something that will
work for us as a whole, but of course, having more folks looking/playing
with the pi would of course speed any and all progress towards the goal of
build our own gaming machine.
I would love to port anything of interest to the pi, but since I don't
know what is of interest, I'm kind of just nibling around the edges (so to
speak) and porting things I've already ported to the mac or linux from
before. I'm of course perfectly willing to help anyone port anything if
they have the desire to make a version for the pi, but until we can find a
better soundsystem for the pi, basic audio games are all we'll be able to
make, since things are constrained by the pi sound at the moment. Of
course, this doesn't mean we can't build up a nice collection of things to
play anyway, things that don't depend on positional audio will work just
fine. I've written to RSG games asking for a pi version of their client,
since python is one of the major languages for the pi, I expect that
porting the rsg client would simply be a matter of including a proper
version of their compiled python code, and poof, it's all done.
Unfortunately, I received no response to my inquiry, so no idea if that's
due to lack of interest, lack of knowledge, lack of message receipt, or
some other reason. However, I'll continue porting things I can get my
hands on, and perhaps, even without a great sound architecture, the pi
could still be used as a basic gaming rig by some.

Hi Travis,
I have been thinking about a Raspberry Pie for a while. You answered many of my
questions with this post but one that I have is how easy is it to set up with a
visual impairment?
Also, you had mentioned that the sound is not great. I assume you can plug a
headset into one?
Considering the headset idea, would it then be possible to install a
third-party audio library such as OpenAL?
You can see where I am going here. I am wondering what would need to be done
here to bring this closer to an audio gaming environment.
Thanks for any feedback or insights you may have.
Have a great day!
Cheers!
Cara

I bought a raspberry pi, case, power adapter, and pre-installed raspbian system
(never did get the sd card with the raspbian installed on it though) and the
entire bill including shipping was around the 85-90 dollar mark. It's an
excellent little unit. It has 4 cpus in it, and runs at 1GHZ, with 1GB of ram.
It uses standard micro sd cards, up to 32GB (if I remember correctly) though
some of the 32 gb cards don't behave properly, so there is that to look out for,
but otherwise, it is truly an excellent system. I'm actually using it as my
main pc at the moment, since my imac went belly up a few months ago, and the
only other machine I have is an old xp machine that has some serious dll
issues, so it doesn't like to run for more than an hour or so at a time,
depending on when/how windows decides to do things. I've never managed to fix
it, because my xp pro disk is unreadable, and I've not found another xp pro hd
I could copy the dlls from to repair my system.
I have other linux systems in the house, but mine was disassembled to give
parts to my son who built his own computer for gaming purposes, and I've not
managed to get the additional parts I needed to rebuild my linux machine, so
the raspberry pi is filling in quite nicely as my main pc at the moment. It
works well enough, and I can run it for about an hour using one of those pocket
juice things, though I've not (yet) experimented with other battery power
devices, although there's one on the raspberry store that claims 8 hours of
usage. I do plan to purchase one of those, so I have a nice portable unit.
I'd actually been considering trying to turn mine into a gaming unit as well,
(thus the writing of the memory game Jake referred to in his post) The sound
isn't anything to write home about, so for the moment, complex audio games
aren't possible, but otherwise, it's quite the neat little unit, and I'm
looking forward to see what else I can accomplish with it.
