Firefox Sound fades

Is this in flash?

Can you give the output of:

dpkg -l | grep flash; dpkg -l | grep gnash; dpkg -l | grep swf; uname -a

If not please indicate what conent is having issues.

Thanks

This is in flash, but now that I have moved some of my mp3 files onto the computer it is happening to them as well, the sound starts off strong and fades to nothing after about 20 seconds.

I am not getting anything when I put the above information into the terminal, possibly I am typing it in wrong? I am getting video through flash, just not sound.

Can you give the output of:

sudo lshw -C sound

The command I give can be directly pasted into the terminal which is why I give the full and exact command

Can you give the output of the first command I gave too

Thanks

My apologies, this has been frustrating me all day and this whole format is overwhelming at first, not sure why I didn't think of copy and paste, might have something to do with the 13 hours I've spent today trying to make this transition go as smoothly as possible.

The output of your first command:
me -a
ii adobe-flashplugin 10.0.45.2-1karmic1 Adobe Flash Player plugin version 10
Linux drew 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:05:19 UTC 2010 i686 GNU/Linux

And the out put of this one:

Thanks for your help, I ran out of options hours ago.

sudo apt-get --purge remove adobe-flashplugin; sudo apt-get --purge autoremove; sudo apt-get clean; sudo apt-get install flashplugin-nonfree

This will give the correct plugin for flash, you have a 32bit Ubuntu install which can make life easier.

Can you also give the output of:

lspci | grep -i sound; lspci | grep -i audio

See how sound goes in flash now.

Thanks

Ran the first command, but still no sound from flash, or mplayer.

Does it work ok in the liveCD environment. Boot to the CD you installed with and select "try ubuntu without making changes"

See if ts ok there.

Is the system a laptop?

It's a desktop, I booted from the CD and had the same problem there, and I ran a CD scan and it said there were no errors found.

I'd check the bug logs to see if there is similar activity reported. make sure you are fully updated with:

sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade

Maybe you could give it a try by turning off 'awesome' power saving.
gksudo gedit /etc/modprobe.d/alsa-base.conf

Find this line at the bottom of the file:
options snd-hda-intel power_save=10 power_save_controller=N

make it 0 (zero) instead:
options snd-hda-intel power_save=0 power_save_controller=N

Save the file, reboot and test.

I ran the update line and everything was up to date. I tried that change, to no avail, and now it seems I've lost my system sound as well. I'll keep searching, any other suggestions in the mean time are always appreciated.

btw. to get detailed output what might be wrong try working through this,
https://help.ubuntu.com/community/SoundTroubleshootingProcedure

the output of alsa report script may show some modprobe options which can be added to alsa-base.conf.
An example of such a file looks like this.

I started going through the trouble shooting steps listed, here is the output of one of the commands (it suggested I post it here) if that helps:

Also not sure if this helps to narrow the problem down at all, but I was having a similar issue with windows. My sound worked great on Windows and suddenly stopped working all together for flash player. The difference is that it still worked fine for media files.

Thanks Sam, that solved my question.
