Hi DJM, 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.

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.
