Can someone reproduce this bug?
Any update?

Alsa is the only sound option when building Firefox. Someone has proposed bug 543779 for changing that. You should use whatever alsa to oss tool to get this to work.

This actually applies to sound in general. Vorbis used in audio tag doesn't work with OSS4 as well.

Assuming you're using an official build (or something built using the official configuration, which uses ALSA), this is a configuration problem on your system.  You need to install and configure ALSA correctly on your distribution so that it uses the OSS backend (via the alsa-oss plugin, I think).

If you're using an unofficial/unsupported configuration where the Firefox audio backend is using OSS directly (using media/libsydneyaudio/src/sydney_audio_oss.c), we'll need to find someone interested in supporting that code to look at debugging the problem.

O, sh...! Almost 2 years of hard researching! 6 major releases till that time! And still no sound.

I've compiled Seamonkey from sources, yet I have no sound what so ever.
So, what can be done to fix sound for HTML5 in Seamonkey/Firefox with OSS? And no, I don't want anything ALSA on my workstation.

Thanks

See above comments. I don't think Firefox supports building with OSS as the audio backend. Please take any further concern regarding Firefox & OSS to the [e-mail] mailing list.
