I think I have this problem as well. Pulseaudio will be working fine. When
sounds play in rapid succession, or a program that emits sound while I already
have a video or music playing, sound will turn into an amalgam of random
screeches, blips, and crackles. It is not always immediate, and sometimes will
go away when one of the sources of sound goes away, but not always.

Currently running a slimmed down custom compilation of 3.7.5-1 on Arch linux.

3.7.5-1-custom2 #1 SMP PREEMPT Sat Feb 2 20:57:43 EST 2013 x86_64 GNU/Linux


Audio controller:

00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family
High Definition Audio Controller (rev 04)
        Subsystem: Elitegroup Computer Systems Device 7c47
        Flags: bus master, fast devsel, latency 0, IRQ 51
        Memory at f7b10000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
        Capabilities: [100] Virtual Channel
        Capabilities: [130] Root Complex Link
        Kernel driver in use: snd_hda_intel

I am able to get sound working again by either killing pulseaudio(which
immediately respawns, or by opening up pavucontrol and changing the profile
from "Analog Surround 5.1 + Analog Stereo Input" to 4.1 then back.(this may be
reloading pulseaudio? idk)

I've attached a recording of the static, in case that give any idea of what's
going. Around 20s is the start of a new video, with a higher volume, resulting
in louder garbled noise.

I've also attached the output of pulseaudio -vvvvvv, started shortly before I
forced the problem(I found that running a certain old game(widget workshop, if
you must know) in wine happened to produce the issue fairly often), though it
occurs plenty of times during day to day browsing/music listening/video
watching.
