Audio from Flash in Firefox does not go to correct sound device

Bug Description

Binary package hint: flashplugin-nonfree

On my laptop I use a USB sound card, and it is selected in the Sound manager as the device for all sound to go to. All applications correctly use it except for Flash (in Firefox) which goes out to my laptop speakers.

This is annoying because I have to listen to the sound through poor speakers instead of through my sound system, but the REAL killer is that if unexpected sound comes on, it takes forever to get muted (because all the keyboard shortcuts / sound icons manage the USB card, the default device), and there is just blaring sound until I can get to the right setting to mute the laptop audio. This can be a real show-stopper in a public place, or just when the audio is literally painfully loud and I can't effectively mute it.

This existed in Feisty and in fact I remember seeing bug reports about it but I can't find any for Gutsy or locate the old ones. Sorry in advance if this was filed improperly. Thanks for any help!

This also happens in gutsy. I have a Macbook C2D and am using a USB headset.

Marking as confirmed as a result of feedback by two other users.

The real problem I think is firefox and not flashplugin-nonfree, as audio from videos played from within firefox exhibit the same issue. Firefox is not picking up on the selected audio device from within Ubuntu, perhaps?

Problem is identical with opera too; neither flash works with my logitech usb but sound of otherwise, So, more likely flash or other?

The following solution worked for me (From http://ubuntuforums.org/showthread.php?t=543878)

"It comes down to getting alsa to use the right card.
Type "asoundconf list"

Then "asoundconf set-default-card INSERTCARDNAMEFROMLISTHERE"

Then alsa has a default card to look for and flash and youtube will work."

I wonder if PulseAudio in Hardy will take of this?

@Charles: Nope it doesn't

Install padevchooser and select manager from the applet menu.
You can see, when flash is using audio, that the channel is occupied on the onboard sound card.

Strange phenomenon: Microphone from the USB Headset works.
But sound not.
Setting default card via asoundconf or via gnome sound settings doesn't help.

Bumping it to medium, because it's an RC...
I wonder if it's a regression from using pulseaudio in hardy now.

ok,
after testing with Daniel T. Chen,

removing pkg libflashsupport helps to get some output on the headset again. But this means, flashplugin-nonfree is not using Pulseaudio.
The same thing happens when you killall -9 pulseaudio and setting the default soundcard to headset e.g.
Sound works.

With libflashsupport + pulseaudio -> no sound is coming over the headset even if its set as default.

It's not a regression; ALSA still works; flashplugin-nonfree still works. It's libflashsupport that's broken.

Hi Daniel. I was just wondering why importance was reduced to low. For the small amount of people this affects, it is a rather serious issue. In my case I had to keep Windows in a dual-boot setup to boot into in order to watch video or listen to music online.
