Comment 2 for bug 153742

I'm having the same problem. No sound with Firefox 2.0.0.8 and flashplugin-nonfree v9 on 64-bit Ubuntu v.7.10 'Gutsy'. nspluginwrapper and alsa-oss are installed. Most other apps play sound fine. I've reinstalled, tried launching firefox with aoss, edited /etc/firefox/firefoxrc and put FIREFOX_DSP="aoss", installed pulseaudio, etc., etc. Nothing I've tried so far works.

I have an AMD 64 Athlon 64 3500+ processor and the motherboard is a ECS RS-482_M.
The on-board AC '97 sound just wouldn't work with Ubuntu at all, so I installed a Ensoniq ES1370 [AudioPCI] and disabled the on-board sound support in the bios and all my other apps work fine with it.

lsmod shows the following:
