I have a fresh install of Debian Squeeze and am getting no sound from flash sources like youtube. Audio from other sources works fine. I've got everything unmuted and cranked up in the hda mixer.

Hi, sounds like your sound card is unavailable for the app (=being used by another app). All you need to do, is quit the app using the soundcard should tell you which app is using your soundcard. Another solution would be to install a sound server such as PulseAudio

Hi.

I ran into that problem when troubleshooting flash on ubuntu karmic on chromium. Turns out flash 9 played the content but had no sound. So i had to revert back to version 10 of the flash player. Firefox got affected as well.

Perhaps you can try putting the flash plugin to chromium and restart the browser, try again and see what happens.

Cheers.

By the way, if you ever get it to work smoothly, let me know.

You might want to look at which processes your username has running. Is there a dead npviewer.bin process?

Which desktop are you using? KDE 4 has a sound configuration applet. Phonon has different configurations for audio and video applications.

Are you using Pulse audio?

Hi,
I too am having no sound in flash. I have recently installed gnash on Fedora 12, as Fedora 12 has no flash support. I have also installed VLC media player from fusion repository for playing some restricted media formats.

Is the sound issue in flash due to no support of some media formats (video/audio) on most recent Linux distributions.

I had this once and after a lot of digging I found that a fix was to delete some temporary files from your home directory (within .mozilla I believe). I can't remember exactly what they were and can't seem to find the link now but I basically just stuck the code in my bash_login file so it ran automatically.

I too have been plagued and frustrated by the problem of hearing the sound in YouTube videos. I use openSUSE 11.1 (KDE 3.5) on a home assembled two year old IBM type computer with Intel motherboard and Turtle Beach sound card. If you have not already done so,install the codecs from http://opensuse-community.org/Restricted_Formats/11.1 using the command line. Simply open a terminal in the same window as the codec download page, type su and enter your super user password.Copy/paste the entire line(s) to the command line. The first two will add the repositories and the third will install the necessary files. Next, go to http://software.opensuse.org/112/en, then Software Search. Click on your version of Suse and type in VLC. This will bring you to a download page. Select vlc-open and after it has installed, click on vlc-open-mozillaplugin. This last file is what turned the trick for me as everything else had been installed previously.Good luck and I hope your results are the same as mine.

I hate having to append my previous remarks but as of today, Monday the 15, the sound problem resurfaced. Sometimes it works, sometimes not. Aaaaarrrrrgh !!

I've been plagued with this problem too, and despite participating in several threads about it and opening one of my own, I've found no relief. Sound works for a little while immediately after a clean boot, usually long enough to play one video, but then it stops. I've pretty much tried everything that anyone has suggested for resolving the youtube "no sound" or "garbled sound" problem. So far, nothing has worked for me.

The only sound that doesn't work is the sound with flash video, such as YouTube uses. All other sound sources work fine.

What you posted Walker2 sounds interesting, but I'm not running Suse and it's not clear to me if it'll work on KDE 4.2.

Hi, after playing around with pulseaudio a bit, and deciding I didn't want it, I read more carefully the Archlinux wiki, and it appears that for some reason, flash uses OSS by default (even though it is ALSA capable). I just disabled the 'snd-pcm-oss' module (blacklisted it) and voilà...

All that is needed is actually to mix several streams into one device, ALSA has (usually) dmix configured by default, but if some app uses the OSS emulation in ALSA, it takes control of the sound card. (and if something is already playing, then OSS can't take exclusive control of the device, hence no sound).

That's an interesting idea Serafean. Unfortunately, removing the module didn't fix the sound for me. Is that the only one you blacklisted? I have a few other oss modules loaded.

Actually, this only did the trick on my XFCE box, with KDE flash sound is still a no-go... (unless I use pulseaudio)

Good job posting this. I had this problem as well but was able to fix it by reading the posts above. Thanks!
