Dolby Digital over TOSLINK SPDIF to Audigy2 Platinum EX
by Luke Macken
Hey Fedora Audiophiles,
I lost an hour last night trying to get this setup working, but to no
avail. I was wondering if there is anyone out there with a similar
setup, or with knowledge on how to get this up and running. Here is
what I'm trying to do:
Playstation 3 -> Optical -> Audigy2 Platinum EX external box -> Computer Speakers
This setup works great out of the box, using Linear PCM 2 Ch. 48
kHz, but when having the PS3 output Dolby Digital 5.1/DTS 5.1 sound, I
can hear the data, but it does not get converted properly, so I hear
crazy pulsing sounds.
I've tried tweaking every setting in alsamixer on every piece of
hardware, but nothing seems to make a difference.
Does anyone have any experience taking Dolby Digital data from an
optical input, and convert the bitstream to analog, before sending it
off to the speakers? I was under the impression that this external
receiver could do this for me, but I can't seem to figure out how to get
it to work.
Thanks!

Future of PowerPC for Planet CCRMA?
by William M. Quarles
Hello Fedora-music list,
For those of you who haven't read, I'm trying to help Fernando get a
PowerPC distribution of Planet CCRMA going for Fedora. I took this on as
an experiment, and boy is it an experiment.
Well, there's news... I don't know if it's good or not yet. Fedora 12
turned my new-old Power Mac G4 AGP into an electronic brick. After much
frustration, I gave up on F12 and tried F11 instead. F12 could not work
in graphical installation mode on my machine (neither with kernel nor
VESA modes), and also during and after text installation it could not
get an ip address, through no fault of my home network at all.
On Fedora 11 I had the same problem with graphical installation, but I
was able to get a text-based network installation to work, then download
most of the needed packages for graphical workstation with applications
through yum at the text command prompt. This was much better.
I'm guessing that X did not work at all for many early Mac G4 graphics
cards on Fedora 11 nor Fedora 12 until recent updates came about, since
at my check Fedora 12 has only been around 3-4 months, and both releases
initially had the exact same problems with X with the installer on my
ATI Radeon 7200 card. I don't know how anyone updated Fedora 12 after a
disc install without being able to get an ip address, neither during
installation nor post-installation. Perhaps something differently
happened if they were able to get a graphical installation to work from
the beginning on F12, I'm not sure.
Anyway, after yumming up Fedora 11 for the ppc on my machine I was able
to get X to start, but the display of fonts appears to be corrupted. My
conclusion is that either
1. There hasn't been much (if any) testing done on Power Mac G4 AGP
models, or
2. There isn't much testing done of Fedora on the ppc platform period
due to the currently low demand for it on non-Intel Macs and Play
Station 3s.
Perhaps things will work differently on the newer Mac Minis that
Fernando mentioned that he would try to get going sometime at Stanford.
But until I can get a more functional install of X at home here, I won't
be able to test any of the potential ppc builds myself. I still have
Fedora 12 installed on two i686 machines in my home, so I would be able
to easily access any build machines at CCRMA, provided that such access
is granted.
Any help that list members can grant is appreciated. I've written some
to the Fedora users list as well, but I use GMANE to access it, and I
don't think that GMANE is getting all of the new messages from the
migration yet due to the insanely smaller traffic on there in recent days.
Thanks all,
William
