- OS Version: 6.1.7601.2.1.0.256.1 (Windows 7 Ultimate x86 Eng)

One would say that's a kind of mysticism, and this is how it looked like, but only at a glance, though.
A few regular updates of (a) Adobe Flash , (b) Google Chrome, with its Flash player included by the way, and (c) Skype during June-July, 2012 - brought some unexpected and unwanted behavior to this bunch of software pieces, they started hanging, just at the most inconvenient situations:
- you start playing a Flash video in Chrome - it hangs up, freezes partly (only the current tab) or sometimes totally;
- sometimes (rather often during a day indeed), during most active hours, Skype hangs up, freezes, as it's been noticed - after an attempt to play a "new message" sound, so that you can see the messages arrived being left unread regardless that you stare at them on and on, and your own messages you start typing and sending - can't be sent out just showing that progress animation against each your message. When it happens, you can even notice the sound "tick" as the failed attempt to play that.
It's been noticed as well, as a temporary workaround, that when it happens (e.g. both Skype and Chrome have hung up, frozen that way, or when one of them has) you just go and open another Chrome tab, open any flash video, it's "trying to start" during a few to ten seconds - and yahoo! - it helps, looking like it's making a kind of break-through - both Skype and Chrome are getting back live and you get some relax... until the next freeze :)
Found out that although the Flash version included into the Chrome distribution was the latest one (Chrome updates handle that), there was still the stand-alone Flash version used by IE, Skype and others - that was not the latest one. So, it's been updated to the latest non-debug one 11.3.300.265.
Some other suspects made me check a list of ideas, incl. the video hardware acceleration used by Flash, and thus some possible incompatibility with the video drivers, etc. But the system/apps logs contained nothing related, and disabling that Flash "hardware acceleration" didn't help either.
Decided to force the Chrome to use only the stand-alone Flash instance, not the one included into the Chrome distribution:
Managed to get the Chrome.exe crash report, just having tried to close it during such a freeze:
A problem caused this program to stop interacting with Windows.

Oh, that "svchost.exe:AudioClientRpc" has brought some piece of hope indeed. Has checked whether the sound drivers are the latest, went into its advanced properties with the suspect of some sound drivers incompatibilities, trying to simplify the sound device usage, turning off various effects one by one - finally faced the reason and the solution. It was the system-wide "Equalizer" on-the-fly enhancement provided by the sound drivers, it turned to be the reason why various applications were hanging trying to communicate with the audio device.
- PlayBack Devices -> Speakers -> Properties -> Enhancements -> "Disable all sound effects" checkbox should be turned ON, that solves this problem in this specific case.
Considering the wide variety of Flash-related crashes, issues, feezes in various OSs like Windows, Linux (specifically Ubuntu), OS X reported recently, the updates from Adobe would be highly appreciated.
In the mean time, looking forward and thanks in advance,
