[SOLVED] Flash/npviewer.bin breaks ALSA sound (not Flash)

After viewing a website with flash, YouTube, etc; mpd would hang. Killing firefox would fix this, more specifically, just killing npviewer.bin would restore sound.
When trying to play something with mpg321 it would just hang with no output, playing something with mplayer resulted in:

Hi!

Which version of emul-linux-x86-soundlib are you using at the time?

I means only 20080418 and perhaps (but not sure) 20080316 are based on alsa-lib 1.0.16 and only those will work properly with flash but they are ~amd64 and alsa-lib-1.0.16.

Hey guys,
I am currently experiencing a problem I don't how to solve at all.
For one week, I haven't been able to use (mplayer or amarok) WITH flash.
If I first play music with amarok, then no sound comes from the flash video (but it is properly playing)
If I first play the flash video, then mplayer tells me
[AO_ALSA] alsa-lib: pcm_dmix.c:996:(snd_pcm_dmix_open) unable to open slave
[AO_ALSA] Erreur ouverture de lecture : Device or resource busy
An other issue is that skype tells me there is a problem with audio playback. However Everything was perfectly working before.
And I can have amarok and mplayer playing music at the same time.

I tried to update to a new kernel, supress oss support, but the problem is I don't even know where it can come from.
Right now I am hesitating of reinstalling a new gentoo....
Thanks

Are you on AMD64 and using nspluginwrapper? If so check out this solution.

Great... This is right on the mark. Pity I didn't find it before going through the hurdle of re-compiling the kernel, re-running alsaconf and the works...

Though the fact that killing npviewer.bin returns sound immediately, it is a funny thing that my alsasound initscript got lost. What could have eliminated the entry from my rc-update db appears to be beyond the solution, which nevertheless works.

cheers. Upgrading emul-linux-x86-soundlibs worked on my amd64 box.
