First of all, please install latest version 0.8.8-2 in unstable.

At youtube.com, you might encounter cookies-related issues:

At the moment, we didn't understand yet what browsers are affected,
what not, what conditions. What acts as workaround in all cases seems to
be removing+blocking cookies from youtube.com.

I tried your configuration with few changes and now my system uses jackd
too but I only have good news: it works fine! :)
FWIW I'm using qjackctl as auto-starter.

Exactly. Gnash can't modify or start with a configurable volume level
whereas .swf applications it plays can do it.
And this is what I found out:
under ~/.gnash/SharedObjects, gnash stores .swf applications and related
data. For example:

SharedObjects/s.ytimg.com/yt/swf/watch-vfl186120.swf
	local copy of youtube movie player
SharedObjects/s.ytimg.com/soundData.sol
	volume settings we was looking for

So when you modify volume level, gnash stores it in that file.
I confirm that at the first access, volume is at maximum level but when
you lower it, your action is saved.
s.ytimg.com is one of the youtube servers and I don't know how many they
are so there might be more than one "first access".

And how to made initial maximum level lower?
Play with levels, IMHO the answer is there.
