Sound jitters on music media playback & flash crackles on... [SOLVED]

Okay, so i've spent a good time looking through these forum threads, the wiki, and Google but  have still been unable to resolve this issue, so am needing some help on this one:

I ran an upgrade on my machine, and ever since have had jittery sound on music playback (using mplayer, songbird, spotify) and to lesser a degree - more crackle-like! - with flash. Trying out games has been fine however. 

I am using ALSA, no pulseaudio, and have the modules installed from here:

https://wiki.archlinux.org/index.php/Realtek_ALC892

lsmod | grep snd*
snd_hda_codec_realtek    52977  1 
snd_hda_intel          21635  9 
snd_hda_codec          68014  2 snd_hda_codec_realtek,snd_hda_intel
snd_pcm                73416  5 snd_hda_codec,snd_hda_intel
snd_page_alloc          7409  2 snd_pcm,snd_hda_intel
snd_timer              19094  4 snd_pcm
snd                    57615  17 snd_hda_codec_realtek,snd_timer,snd_pcm,snd_hda_codec,snd_hda_intel
soundcore               5442  1 snd

Running songbird, spotify, mplayer and firefox (which uses a process called "plugin-containe" for YT) simultaneously, I have been trying to single out the common file used by each application with fuser, seaching through /usr/lib, writing the results to a text file:

 fuser -v /usr/lib/* > fuser.txt && grep "songbird"  --after-context=3  --before-context=1 fuser.txt
...

/usr/lib/libssl.so.1.0.0:
                     stuart    ....m songbird-bin
                     stuart    ....m spotify
                     stuart    ....m plugin-containe
                     stuart    ....m mplayer
...

Downgrading relevant packages (openssl, as above, for example) hasn't changed anything, i.e. I have not found the culprit package.

My question is what other directories might I try searching through? Or what else might the problem be?

I have tried the below fix too with no success.

Ideas would be gratefully received.

EDIT: We'll pretend that the solution wasn't to mute non-existent speakers in alsamixer, and was in in fact, actually, extremely complicated..
