Just thought I'd add to your points about sound from DTUs and Flash. From
what I've been able to find, Adobe have written Flash Player with only ALSA
support since version 8, whereas the Sun Ray sound module utilises the older
OSS sound model. Programs that can 'talk to' OSS should work fine, but the
Linux flash player as provided by Adobe will not. Adobe have released an API
with Flash 10 for people to back port OSS and other stuff into, but I don't
think anyone's done it yet.
I had to rebuild the esound RPM to disable ALSA support, as with ALSA
support compiled in, I was unable to get the CentOS 5 ESD to honour the old
OSS $AUDIODEV environment variable. Now you I just enable software sound
mixing in the Gnome Sound preferences, esd starts at login and works a
charm.
Best compromise I have to play YouTube though is through a Windows
terminal services client and put up with the 5 second sound delay.

Subject: [SunRay-Users] [SOLVED] -- Re: SRSS 4.1 on RHEL 5.2 and CentOS
5.2: DTU's play no sound
I solved my problem ... at least to the largest part! So in case
anyone runs into the same problem on RHEL 5 and/or CentOS 5 - here is
how I solved it (well ... 95% of it)
Google for "Dag Wiers", "EPEL", FreshRPMs, Dries, NewRPMS, and "Planet
CCRMA"
=> these are extra-repos for RHEL 5 and/or CentOS. Google knows them
all. Read the install instructions for each of these repos carefully.
If you get "404" errors when you try to run "yum update" check the
affected *.repo file, in most cases it's enough if you replace the
variable names they sometimes put in there manually with the correct
value. e.g. the "PlanetCCRMA" repos had a line saying something like
baseurl=http://........ /$baserelease/$basearch
For some stupid reasons the variables would not resolve correctly on
RHEL 5, so I replaced the variables manually with this:
baseurl=http://....... /5/i386
After this it should work.
So once I got "yum" working correctly with all of the above repos I
simply installed these packages:
gstreamer-plugin-bad
gstreamer-plugin-ugly
These packages pulled in lots of other dependencies (faad, ffmpeg, +
dozens of other packages). Then install any MP3 player, e.g.
yum install amarok exaile
... To install both "Amarok" and "Exaile". Now when I open any MP3
file I can definitely hear it playing correctly on the DTU's
speakers!!
I have still no sound on YouTube but I don't really care so much about
that. Probably it's just another extra-package that is missing (e.g.
"flashplugin-nonfree-extrasound" ??? I didn't bother to search for it
yet on RHEL or CentOS ...) but as far as I am concerned this problem
is solved ... at least for me :-)
I thought I post this here in case anyone runs into this thread via Google
....
Thanks to all + best regards,
DJM.

Hello all,
I seem to have a similar problem to that was described by William
Goodman in this posting:
http://www.mail-archive.com/[email protected]/msg11023.html
My setup:
- RHEL 5.2 i386 running on a Sun Ultra 20
- CentOS 5.2 i386 on the same machine (dual boot; for testing purposes)
- SRSS 4.1 on both partitions; works tip top with both distros (except
for the sound problem)
- Sun Ray DTU's: Sun Ray 2, Sun Ray 170 and Sun Ray 270 ... I
experience the same problem on all of them
The symptoms that I experience:
- normal applications seem to produce no sound (e.g. there is no sound
in Firefox, YouTube, etc.)
- I get the same problem on both RHEL 5.2 and CentOS 5.2 (on the
bright side: this really seems to prove that CentOS is 1:1 compatible
with RHEL, even errors are reproducible 1:1 :-) ...)
- GNOME's volume control applet is being loaded but right-clicking on
it and then selecting "Open Volume Control Ctrl+O" produces this
error message:
"No volume control GStreamer plugins and/or devices found."
(clicking on "Close" removes the message again). This too happens on
both RHEL and CentOS ...
- Environment variables are being set though:
$ env | grep AUDIO
AUDIODEV=/tmp/SUNWut/dev/utaudio/utdsp-0
UTAUDIODEV=/tmp/SUNWut/dev/utaudio/utdsp-0
- going into the "Sound" preferences via the menu: " System >
Preferences > Sound "
... and then going to "Sound Events" (which is set to 'Autodetect')
and clicking the "Test" button there it might produce a distorted
sound the first time I click the button (this does not always happen),
but on the second and all subsequent clicks it then produces the
normal GNOME test sound you're supposed to hear.
- going to the "Sounds" tab and clicking on the 'play' button of any
of the preset sound events there produces no sound though, e.g. I can
click on "Question dialog:", "Warning message:", and so on, but
instead of hearing any of the configured *.wav files all I get is
silence.
I'd be thankful for tips on how to resolve this :)
Thanks in advance!
DJM. / Switzerland
