Sorry the result is more or less the same. Maybe slightly better.
Still some cracks (at random).
I have checked CPU, below 40%. Stopped XBMC, CPU less than 20% still some cracks.
Terminal
dmesg | grep -i fiq
[ 1.100643] dwc_otg: FIQ enabled
[ 1.100668] dwc_otg: FIQ split fix enabled
[ 1.100643] dwc_otg: FIQ enabled
[ 1.100668] dwc_otg: FIQ split fix enabled
Do you have some more suggestions?

no until I run it myself.
btw: have you not reported that you changed one of the FIQs to disable?

oh my dear lord what a crap RPI is.
this is for sure not lack of power or something... and I'm so much pissed off. probably only part having value on RPI is its paper packaging box.
but you have it to throw away first. to save a forest.

@Killerbee
prepared firmware from 11.April and 3.13.6+ kernel from ->next.
both are in devel (xbian-package-kernel 1.3.7 and firmware 1.4.15).
((don't install packages with suffix -6q by mistake - it's cubox))
also check those kernel scheduler parameters - although I have feeling for those parameters to be active "Automatic process group scheduling" and "Control group support" must be compiled in.

Many thanks for these kernel and firmware packages! Finally I am able to listen to my favorite music without pops and clicks!
I didn't change anything to my cmdline.txt
This is my current cmdline.txt file
Terminal

[edit]
dmesg shows alot of these messages:

@Killerbee
really ??
please report back later if you hit some unpleasant side-effects as I was following the topic a bit lately and have to say that I'm not fully convinced about "readiness" of this patch.
but definitely will try the USB audio again because last time I was very very angry (about the completely f***-up USB implementation on RPI)
on the other hand of course I'm glad we have a solution.

@mk01
Until now (a few hours) no distortion/cracks/pops at all!
I am even able to watch a HD movie (shared on my other pi using smb) and listen to spotify on the same PI without any distortion!.
Until now no unpleasant side-effects (for me)....
I am a happy man
Thanks again

FYI
Terminal
dwc_otg.fiq_enable=1 dwc_otg.fiq_fsm_enable=1 dwc_otg.fiq_fsm_mask=0×7
I just see a (none blinking) cursor at the top left corner.
No ssh login possible....

me too. it freezes right on the firmware. even kernel is not loaded from sdcard.
I remember some forums saying 0x3 or even 0x1. but I'm not sure this one is this problem
