Also the Volume Control in Windows were all at 100% on Firefox and everything else in the list
Are you seeing this for every video or only some?  Can you please post a link to a video where you do see this?  Would you mind also attaching the report produced by dxdiag.exe and the speaker and output format details from the Sound control panel please?

This is for every video that's served without flash/silverlight

Here's the dxdiag output

The sound setup in control panel i have it to 24 bit, 192000 Hz

Thanks, that gives me a couple of ideas but I'm still guessing at this stage.

It sounds like your audio hardware/drivers has a volume limiting feature.  I don't know why that might affect Firefox but not Chrome (perhaps the way we configure the audio streams triggers a different path in the driver) but would you mind testing with that off (if it's on) to see if it makes any difference?  From Googling around, there should be a "Conexant Smart Audio" control panel where this is toggleable.

It could be that the communcation ducking is kicking in (but again, not sure why us and not Chrome), so it would be interesting if you could report the results of testing with the communications tab of the sound control panel set to "Do nothing".

The other guess is an interaction with our resampler since your hardware is configured for 24-bit/192kHz.  Would you mind testing Firefox's audio with that set to 16-bit/44.1kHz (or as close to that as possible, if that option isn't available) please?

I've set it to 16 bit 44.1kHz and i have SmartAudio in control panel but it has no option to disable it.

If you're still able to reproduce this problem, would you mind testing the special build available here:

...and letting me know if that makes any difference?  Thanks!
