Flash Player, Firefox: sound in blackbox but not KDE

DaneM · 07-02-2005, 04:15 AM

Hello, everybody.

I'm setting up a Slackware 10.1 box for a friend, using old components (233MHz P2, Dell OptiPlex GXa). Everything is working pretty well now, except that I don't get any sound when watching flash animations (such as www.homestarrunner.com) from firefox in KDE. In BlackBox everything works fine.

Things I've tried:

Code:

$ aoss firefox

Code:

# ln -s /usr/lib/libesd.so.0 /usr/lib/libesd.so.1

Clues:

When I try to do:

Code:

# cat /dev/urandom > /dev/audio

while in KDE, it tells me that the resource is busy and won't let me do it. It works fine in BlackBox (spits static out of the speakers). This suggests that something is hogging the sound card; the problem is that I don't know what!

Any help you can give me would be well-appreciated.

Thanks!

Try going to the KDE Control Center (kcontrol) and check out the "Sound & Multimedia" section. It may have a few options that you may need to adjust.

Thank-you for your post!

I messed around with a lot of stuff in the KDE Control Center, but to no avail. Do you have any other suggestions?

Thanks.

Have a look at the processes running by doing ps -A. If you notice anything that may be hogging /dev/audio, kill it.

Also try fuser /dev/audio

Edit: Here is a better idea. Do:

Code:

 fuser -v /dev/snd/*

and

Code:

 fuser -v /dev/dsp*

and

Code:

 fuser -v /dev/mixer*

and

Code:

 fuser -v /dev/audio*

I'm sure you'll find the process blocking sound.
For some reason I think its going to be "artsd" (Just a dumb guess)

If you run KDE, it starts artsd sound daemon by default and it open sound devices in exclusive mode. If some application can't use arts for audio and requires direct access to sound devices, starting it with artsdsp wrapper may do the job.

artsdsp fixed it! The command to use on firefox is:

Code:

artsdsp firefox

Thanks a bunch to everybody who posted!

Hi,

Sorry to resurrect an old thread, but I've been scratching my head in regards to flash sound using KDE and Firefox.

I am running current, KDE 3.5 and the latest Firefox, flash 7.

I can get sound when I run from wmaker, but not KDE, at least not reliably. I tried the suggestion here, and have seen it other places. But, when I run

Code:

artsdsp firefox

I get an error that says artsdsp only works with binaries.

Thx in advance for any advice or support. Silly to be so frustrated over such a simple thing.

I'm going to guess that your firefox command is not actually named firefox but something else like mozilla-firefox. from a terminal if you try to launch firefox manually using firefox, what happens?

Another thing to check is to righ click and view the properties for your launcher icon and see what command is actually being executed.

desertViking · 04-25-2006, 11:16 AM

Thx for the reply!

The command is executing from

Code:

/usr/sbin/firefox

(could be /bin), but I didn't check to see if it was a script or binary file. I'll have a look at that when I get home.

I ran into the same error message, however my firefox is run from /usr/bin/firefox (which is a symlink that points to /usr/lib/firefox-1.5.0.7/firefox... and yes, the symlink works)

I've tried:

Code:

$ artsdsp firefox

and

Code:

$ artsdsp /usr/bin/firefox

and

Code:

$ artsdsp /usr/lib/firefox-1.5.0.7/firefox

All three produce the same error.

Have a look at my solution here:

http://www.linuxquestions.org/questi...d.php?t=502891

I added my user to group "audio" with Slackware 11.0

This line works on Ubuntu:

$ export FIREFOX_DSP=artsdsp
$ firefox

If not, you could edit /usr/bin/firefox. Near the end of the file, you'll find something like "exec ${MOZ_PROGRAM}". Inserting artsdsp after exec should work.
