Tnx

Thor
Sys : FC12/JRE 1.6.0 20/Firefox
(years later - sorry for my wining...)

i could start listing off things to try.
BUT What have you done and tried already ?
and did sound work before ??? now .

Works just fine here.
Debian sid 2.6.32 kernel Firefox 3.6.8 and in Chrome 6.0.472.14 dev
Java(TM) Plug-in 1.6.0_21
alsa 1.0.21

Works with the 2.6.35 kernel and alsa 1.0.23 as well.

Hi,

Both of ya: BIG tnx for a reaction...

Ok, here's a short digest of the quest I did:
- installed FC12
- installed the JRE plugin from Sun/Oracle in /usr/java/jre1.6.0_21/
- made a symlink to the libjavaplugin in /home/T01/.mozilla/plugin (home folder of the user), owner and group were transfered to "T01" (the user) using chown
- tinkered with the alternatives next, as the Sun JRE was not visible in the plugins-pane of Firefox...
- I added the Sun JRE in the libjavaplugin entry of the alternatives, set it to active (the bullet) with priority 1000 (the max I could set it to)
- also checked the read-perms of the folder (/usr/java/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so) and x-perms were available, execute should have been possible...
- installed FC13 and went tru the whole song again...

I does work on FC10, there I did (about) the same - give or take some things that did'nt needed to be done as they did'nt have any impact anyway...

What I do notice is that system-configure-sound does not show ALSA as a device, but only the hardware - no virtual device as I do have in FC10...

Distro trouble? Broken stuff (I did update the FC13 - after a netinstall - it was an absolute fresh install)

BTW - what is the life cycle of your distros? Fedora has one of about six months now, and having to do that dance over and over again seems a bit of a waste of time, my projects dont wait...

Tnx!!

And all wellness to you!

(still crazy after all those years)

Take a look at http://www.mjmwired.net/resources/mj...-f13.html#java

Also see http://plugindoc.mozdev.org/linux.html#Java

Debian Stable is usually released about every 2 yrs,. You can use the backports and volatile repos to get newer packages. Stable only gets security and the rare bug fixes.

Personally I run Debian unstable it is more a rolling release, with continual updates. I have had the same install for 6 years, haven't had to reinstall so far.
I do apt-get update;apt-get dist-upgrade daily to stay updated.

you do know that fedora has the default java-icetea installed bu default ?
and by installing the sun java on top of a already installed java that messed up the currently installed java

i am not running fedora right now BUT
(/usr/java/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so)
that is not the location of the already installed java in fedora
it is in the "alternitaves " folder

fedora changes SO VERY fast
that what worked in 10 might not work in 13
3 newer versions

the java install changed i think in fedora 11

Hi,

John : thanks, this means I have to re-learn how to install Java. A "mistake" I made was to assume Fedora would have some continuity in the way it's to be treated, it seems it does not. I looked at arch linux, and debian, maybe a change of distro is in order. Sadly, I really like(d) Fedora...
craigevil : big tnx for the boost here, I have the (hopefully wrong) impression that Linux is open, yet not acessible. I do hope I'm wrong...I dread the day I HAVE to revert to windows...
Lemme have a look at debian...
Eh, I'm so lost, I dont know if I have to change distro, or re-learn how to install Java. Maybe an uninstall of the icetea?

Hey, it's about midnite...and I just got of work...I'm rambling...

Wellness and goodnite good people!

Thor

Hi again,

Wow, craigevil, the links you gave are just the pick-me-up I needed right now.
I'll try that out asap...but now, the little munchkinks tell me to have a nap first...

Tnx, dudes!!

Thor
(happy again...)

yep that is fedora it changes very fast
the Mjm pages are one of the best help pages for fedora
so is the fedora docs
http://docs.fedoraproject.org/en-US/index.html

Hi,

Ok, so, here's what I did: I installed Debian :D . Smooth install, be it that some servers were not accessible (at the time) - I tried out the runescape, and still get no sound...

Using Lenny, kernel 2.6.26-2-686, latest JRE (1.6.0_21) and Iceweasel...

But, all in all, Debian seems like the way forward for me...if it has a lifespan that exceeds that one of Fedora by a couple of years.

In case you're wondering, this is what lshw found:

description: Space-saving Computer
product: Pentium(R) 4 processor 2666 MHz
vendor: Hewlett-Packard
serial: czc3280v5z
width: 32 bits
capabilities: smbios-2.3 dmi-2.3 smp-1.4 smp

and a whole slew more, there's a 250Gb SATA disk and 1.5 Gb memory...

Something MUST be possible here...

Man, there goes the project...again.

Tnx for some insight - if possible, guys.

Wellness

Thor

Sounds more like you need to get your soundcard working properly.
take a look at Trouble shooting ALSA on Debian - LinuxQuestions.org : http://www.linuxquestions.org/questi...n-debian-3018/

For the Java web browser plugin, install either the free icedtea-gcjwebplugin (Lenny) or icedtea6-plugin (Squeeze) package,
or the <non-free> sun-java6-plugin package. For other Java programs, you can install the default-jre package to get a Java runtime;
use "apt-cache search java-virtual-machine" to see other implementations. The best options are probably openjdk-6-jre or sun-java6-jre (non-free).

$ apt-cache policy sun-java6-plugin
sun-java6-plugin:
Installed: 6.21-1
Candidate: 6.21-1
Version table:
*** 6.21-1 0
500 http://mirrors.kernel.org sid/non-free Packages
100 /var/lib/dpkg/status

Update Iceweasel to the version in the backports repo.I would also update the kernel to the backports one.
See http://backports.org/dokuwiki/doku.php?id=instructions

Hi,

I just (simply) re-installed Debian added Pulseaudio and I have system sounds - quite a bit of them...but, no sound in the JRE. :S

I used the Sun JDK 1.6.0 21 and the JRE from that set.

Are we looking at a security problem here?

Tnx 4 yur hlp!!! :D

Thor

By the way - anyone else had this problem? And found a way to fix this? I'd like to head/read from you...and your solution. I'm still slaying in silence here (in Runescape) and I would like to hear the agony of the ones I slay...

Ok, I just want to hear sounds in Java...:D

Please...

Thanks

Thor

Well, for one I dont think it is a security problem...and I cannot install JMF...

If any-bo-dy has something clever/usefull to add, please do...thanks

Thor
:-(

Hi,

In the (bleak) hope of some answer/solution...I had the same effect on a PC where Runescape does work. The VLC was still active, and I did not get any (ambient) sounds in the game.

I re-installed PulseAudio on the Debian machine but without any difference.
Can it be that the system-sounds get in the way? Something else is in the way? How do I figure out what wants to make sound and thus hogs the speakers - so to speak?

Thanks

Thor

This may be a silly question, but did you check the package manage to see if any additional components need to be installed? I didn't realize you needed to install other components to get Rhythmbox to play mp3 in Ubuntu. USed the Synaptics package Manager, selected the needed packages, and now I have sound.

...hi RealGomer...and...thanks. You've set me thinking here. It seems like one of three (now two, before I read your answer I saw only two) options:
- a security problem - JRE is not allowed to play sound because of the sandbox thing
- something was not (properly) installed.
- annother program/module hogs the soundcard...

For the JRE to work as needed, I guess more must be done than unpack the thing somewhere centrally and make symlinks...
