[gentoo-user] no sound when playing flash

[Stefan Istvan]

Hello List,

I have two machines with Gentoo Linux installed, and one of them I don't
hear sound when playing flash anims either in konqueror or in firefox.
On the other machine I hear sounds well in flash anims. Other
applications play sound well.
I don't find any significant differencies between the two install, so I
thought I ask it in this list.

Where should I search for the solution?

Thank you for your help in advance,
Istvan

Well, the difference between the flash plugin and most
other programs that play sounds is that it only
supports OSS not alsa or arts. So the problem is that
you either have OSS emulation disabled in the kernel
or the soundcard only supports one stream at a time
and another application is using the soundcard (if you
are using KDE that program is artsd)

Assuming you are indeed using KDE it can be fixed in
Konqueror by checking the "Use artsdsp..." in the
netscape modules configuration tab in Konquerors
properties.
For a general fix see the alsa documentation on how to
enable dmix for OSS emulation too.

I once had the same problem, solved it using ESD (well, not the best
solution, but it works), so, at my startup script I have "esd &" and
flash anims have sound...

Try it, open any console and type "esd &" and try flash...

It's not only the best solution it is the only solution.  Flash uses esd for 
sound.  You can start it everytime you start your web browser or you can add 
esound to your default run level.

eh? I have sound with flash and I don't have esd installed.

I don't have proper hardware mixing though, so when I want to hear
sound with flash I usually have to restart firefox or it doesn't work.

Presumably this is fixable, and is due to flash using oss rather than
alsa, but I haven't really tried.

On a computer with a soundcard that does do hardware mixing (and without
esd installed) I could get sound with flash whilst other things were
playing sound though.

Didn't use to be the case, went googling and found that it no longer requires 
esd it just uses OSS.

Or as I found there are alternatives here, try launching firefox with artsdsp 
firefox, or alternatively aoss firefox.  This will play all sound through a 
muxer and will allow it to play nice even on machines without hardware 
mixing.

So to recap, you don't need esd anymore, just working OSS (ALSA provides OSS 
compatibility).  If you are having trouble with it playing while other things 
are playing sound try using aoss or artsdsp to mux the sounds for you (or esd 
if you like).

aoss firefox works, and I've changed line 454 of
/usr/libexec/mozilla-launcher to 

aoss "$mozbin" "$@" &

which will hopefully do the same thing

I've tried to set up the things you suggested, but everything remained
the same.
I've tried it using blackbox instead of kde, and checked that artsd not
running, but sill heard no sound from flash anims, though xmms and
mplayer had sound.
So I think it is not only kde problem. I also tried it from konqueror
and firefox, with the same result.

Doesn't solved the problem, but thanks.

I tried lunching firefox both with artsdsp and aoss, but when I load the
flash page, first it produces sound, then firefox is freezes. I tested
with http://www.kubrick2001.com site.
If I start konqueror with artsdsp or aoss, it plays flash anim, but
still with no sound.
