Somehow XMMS and Firefox (or rather Firefox media plugins) seem to
compete over sound resources.
If I start XMMS and then, say, go to YouTube to watch a video, there's
no sound from the browser. I have to kill XMMS, browse again, then it
works.
I am under the impression that it only happens with Flash movies, but
those are anyway the only ones that play directly in the browser - for
the other formats I use the MediaPlayerConnectivity plugin for Firefox
and configured it to launch Xine for WMV, Qt and Real movies.
What's the cause and how can I fix it?
Fedora Core 5
ALSA-1.0.11

The reason is that Flash and xmms both use old OSS for sound, which
allows only one app to access the soundcard at a time. Configure your
XMMS to use alsa and start firefox inside an aoss-environment with the
command "aoss firefox" instead of plain "firefox".
And bug the authors of every app that is still using OSS as default on linux...

Hi Arnold. Seeing another post suggesting using aoss for the webbrowsers, I
changed the command for opera to aoss opera. I'm using a realplayer plugin on
it for the BBC radioplayer from bbc.co.uk. But what I am finding with aoss,
is that there is now quite a lot of crackling on the sound. A bit like the
sound of electrical sparks.
Now I can listen to Internet radio, and listen to music at the same time,
which isn't easy, but at least it proves that starting opera with aoss works.
The problem I had was listening to Internet radio, using realplayer, and
using Gaim at the same time. The realplayer plugin would grab the soundcard,
and Gaim had no sounds. When I ended the Internet radio session, Gaim would
play all it's sounds from the beginning of it's session. all a bit bizarre,
and quite funny.

Alternatively, you could try to install
http://gige.xdv.org/soft/libjackasyn/
which works similar to aoss, but lets you redirect oss output to the
JACK server.
I installed it recently in order to listen to www.pandora.com
but I have to confess that I get a lot of crackling, making the
listening experience very unpleasant. Have to investigate this issue
soon (or wait for the new ALSA Flash version ?)
Who knows, it could fit some people's needs, though ?

It's because your card lacks hardware mixing support and Flash only
supports the OSS API (/dev/dsp) which bypasses ALSA's software mixing.
The only solution is to get Flash to support ALSA natively, or get a
hardware mixing soundcard.
You might be able to work around this limitation of Flash by setting
FIREFOX_DSP to "aoss" in /etc/firefox/firefoxrc.

Probably true, it's a cheap on-board AC'97 chip:
# lspci | grep audio
00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)

Damn, aoss is not available on Fedora. :-( I had to pull the aoss
src.rpm from PlanetCCRMA and rebuild it on my system to obtain the aoss
executable.
But still, my Firefox does not seem to use the FIREFOX_DSP variable,
either in /etc/firefox/firefoxrc, or in ~/.firefoxrc, or as an exported
variable in the shell that launches Firefox.
The only way that it works is to launch Firefox like this:
$ aoss firefox
Then it works, XMMS and Flash have sound at the same time.
Is that some kind of compile switch for Firefox, that enables that
feature, and it's disabled on my distro?
P.S.: For the record, my XMMS uses the ALSA output plugin.

You have all alsa-related packages installed? Does Fedora have an
alsa-oss package?
If it's really unavailable that has to be considered a bug. As you have
seen, it's sometimes the only way to make sound work properly!

The only way that it works is to launch Firefox like this:
Hmm, it might be a Ubuntu thing. Did /etc/firefox/firefoxrc exist
already, or did you have to create it?
$ aoss firefox
Then it works, XMMS and Flash have sound at the same time.

Other people have told me they have no /etc/firefox/firefoxrc. It might
be specific to my distro.
I guess you could just move firefox to firefox-binary or something, then
make /usr/bin/firefox a script that just does "aoss firefox-binary".
But, this is really the kind of thing your distro should handle for you.
File a Fedora bug report.

that's interesting, as it is available for me on FC5. I don't remember
adding it specifically, and I clearly didn't add it by source.

that's how I use it.

By the way, version 9 of Flash Player for Linux is going to use ALSA and
lots of other cool stuff:
http://blogs.adobe.com/penguin.swf/2006/07/api_review_1.html
It seems this is gonna be a very much better flashplayer than we've had
in the past... (Not that I like Flash, though...)
