neither are required.
I've never seen an issue in a fedora's 3-8 in relation to sound on my 
PC's. I might not update daily, but more than weekly for sure, and mp3, 
flac, wav, dvb-mpg, dvd etc have continued to work. I'd be less sure 
about my nvidia cards s-video output, which I do have trouble with.

I can't think of any manual thing that I needed to do with PA for that 
to work; in fact I was pleasantly surprised it does work, whereas the 
previous alsa based way didn't {on my hardware}.

Many modern sound cards digital attenuators actually have gain as well. 
To avoid distorting digitized sound that uses the full digital scale, 
you may need to limit the wave input fader to 80, 70 {for mine} or even 
50%. There are pulse audio settings that I think can limit / scale the 
volume slider to only set the chips attenuator to unity gain.

Don't forget the Marantz serial RS232 controlled surround/multiroom amps 
with heaps of inputs - and build some control of its switching and level 
control into an app for linux [*]
