Bugzilla Bug 131237

Hello,

Every time I upgrade mozilla-firefox, it stops behaving nicely with regards to
mixing multiple audio streams.  (My laptop doesn't support audio stream mixing
in hardware, and as far as I know it isn't possible to do oss software mixing) 
This is particularly annoying with flash-enabled websites, as they don't play
any sound unless firefox was the first application using sound to start.  The
simple solution to this problem is described here:

http://gentoo-wiki.com/HOWTO_ALSA_sound_mixer_aka_dmix#Firefox.2C_Mozilla.2C_RealPlayer.2C_Skype_.26_Co

I'd like it if there was a USE flag for firefox that caused the
/usr/bin/firefox script to be installed using "aoss" instead of "exec", so that
this didn't break everytime someone in my situation upgraded mozilla-firefox.

Created an attachment (id=85468) [details]
Patch to mozilla-firefox-1.5.0.2.ebuild to add "aoss" USE flag

Here's a patch that adds an "aoss" USE flag.

When enabled, it adds "alsa-oss" as a dependency, and changes "exex" to "aoss"
in the /usr/bin/firefox script that gets installed.

Completely unneeded... Both realplayer and netscape-flash play multiple sounds
just fine when alsa-driver is compiled with USE="oss". If that's not the case
for you, then fix your sound setup instead of requesting USE flags for Firefox. 

Also, no aoss is needed for that. The wiki howto apparently needs some update
wrt dmix as well, it's been default in alsa for a while.

jacub i think you're wrong. you need aoss wrapper to use dmix with oss
emulation.

however a better fix could be the mozilla launcher patch

As said, never needed any such thing like aoss here...

Enabling USE flag oss on media-sound/alsa-driver works for me! Thanks Jakub

Here it does not, I have always had the oss flag set in /etc/make.conf and
flash audio in Firefox has always refused to play if something else has used
audio since opening firefox.

I suspect that it may have something to do with the sound card. It could be
something such as soundcards which have hardware mixing work with just the oss
flag but aoss is required for those which do not.

Yes, that's what I suspect is at fault as well.  I've got an AC'97 audio
controller, and as far as I'm aware, it doesn't support mixing multiple audio
streams in hardware.
