Perry, at this time, let's just go through only one item, ie., the PCM 
issue which made me feel like a complete idiot. :)

I take it you have video in youtube at firefox but no sound;

Do you have the Kmix icon at the system tray?
If not, open command and enter 'kmix'
LEFT click on the icon and click 'mixer' button.
Do you see a channel with PCM?
If no, at the settings, click configure channels.
Then tick PCM button. You're done.
Make sure you slide up the volumn level up, too :)

Regards,
Goh Lip

note: if this is not the issue, let's tackle this some other time.
I need to take about 8 hrs off.
