Angry Macromedia Flash Audio PROBLEM!!


I am using Mozilla Firebid 0.7
This problem also occurs in Mozilla and Galeon.

Hello. In Macromedia Flash, the audio WAS fine. Completely fine. But, now the audio is all choppy and "chipmunky" as described in an old thread. This happened before, but ater reinstalling it it worked fine. But now it's all totally broken (even after reinstalling several times)!!! I looked at other threads here but they weren't helpful. What is the problem? All my other audio is fine. I'm convinced it's a flash problem. But reaching techincal support on their web site is IMPOSSIBLE! They want a serial number! The flash plugin doesn't have any serial number! If anyone has a serial number please tell me. I'm so mad, I will snail mail the question the the CEO of Macromedia if I have to! Or even a petition!

P.S. Does anyone else have this problem? I read an old thread here about the same problem, but it didn't help. It looks like a bug in flash. I am just furious at the Macromedia support policy! I mean, it's their product and they should provide help (and actually fix bugs! Maybe its so hard to contact them the bug reports never get to them!)

I have had some probls with jerky sound with Flash too, and in my case it was due to bad sound drivers. I have a nForce-based mobo, and the drivers provided by nVidia don't work well with Flash. After I switched to ALSA drivers, all is fine.

It doesn't seem to be your case, since you say audio used to work for Flash... anyway, maybe trying a different sound driver (if at all possible) might help.

Question

I have the same problem... Audio through a flash web page is "choppy" and "chipmunky"...
...but other audio, like through XMMS MP3 player and system sounds are fine.
Using Fedora Core 1, Mozilla 1.4.1 and Flash plugin 6.0 r79.

What gives?

Thanks,
Chris

Chris, you don't make it clear whether you use ALSA or OSS. If you use OSS, you might wanna consider switching to ALSA, that solved the problem for me.

Using OSS right now...

I tried to switch to ALSA by following example here:
http://foolish.digitalinc.info/docs/alsa/
and here:
http://www.alsa-project.org/alsa-doc...odule=intel8x0

but it wont work...

I followed exactly...
my /etc/modules.conf looks like this: (default fedora install)

# ----------------------------------------------------------------------------------------------------
alias eth0 sis900
alias usb-controller usb-ohci
alias sound-slot-0 i810_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
# ----------------------------------------------------------------------------------------------------

I commented out the last 3 lines
and tried to add this:

# -----------------------------------------------------------------------------------------------
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-intel8x0
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

# -----------------------------------------------------------------------------------------------

That didnt work, so I changed it all back to the default fedora install...

Hmmm...

The instructions you followed seem to cover every relevant aspect, so it should have worked AFAICS...

Could you please explain better how exactly it did not work (error messages and such)? How far did you go? (kernel-module installation, modprobe etc.)

1st...
My kernal is 2.4.22-1.2166.nptl athlon

downloaded 4 files:
alsa-driver-1.0.2c-1.fr.i386.rpm
alsa-lib-1.0.2-2.fr.i386.rpm
alsa-utils-1.0.2-1.fr.i386.rpm
kernel-module-alsa-1.0.2-1.fr_2.4.22_1.2166.nptl.i586.rpm

installed rpms like this:
rpm -ivh *.rpm

when I did this from command line it displayed something like:
alsa-driver-1.0.2c-1.fr.i386.rpm **********************100%
alsa-lib-1.0.2-2.fr.i386.rpm ****************************25%
alsa-utils-1.0.2-1.fr.i386.rpm***************************75%
kernel-module-alsa-1.0.2-1.fr_2.4.22_1.2166.nptl.i586.rpm****************100%

Then in KDE I went to the rpm & clicked on each one, RPM says each one is already installed so I assumed that RPM installation was ok...

then I opened /etc/modules.conf and commented out
#alias sound-slot-0 i810_audio
#post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
#pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :

then put in what the ALSA site told me to for my chipset (i810)

rebooted.

got a system message that said:

Error while initializing the sound driver:
device /dev/dsp cant be opened (no such device)
The Sound server will continue, using the null output device

typed: lsmod |grep snd
got nothing... just my command prompt back..

tried to run alsamixer from command
got this:
alsamixer: function snd_ctl_open failed for default: No such device

no sound worked at all after this...

It makes sense. So far, it seems all went fine.

Mmmh... this is bad. It might not be the only problem, but it certainly won't allow you to use sound. So, let's try to fix it.
First, check if there is indeed a /dev/dsp device on your /dev/ dir:

ls -l /dev/dsp
crw------- 1 costa root 14, 3 Sep 15 10:40 /dev/dsp

If you don't have one, you will have to create it as root. IIRC this should do the trick:

/dev/MAKEDEV sound

I guess this wouldn't hurt either:

/dev/MAKEDEV alsa

(read the manpage)

Let me know how this comes out.

Well, let's first fix the previous problem, then we see if there's anything else to fix, ok?
