[Blink] Blink hangs on Linux when accessing sound device

As our code is the same on all platforms and on all my Linux boxes it simply works, I can speculate on the following:
1. It depends on a particular dependency that gets installed in that OS
2. It depends on the type of hardware
Can those who have this problem let us know about the combination of hardware chipset and alsa drivers installed in their system where it does not work?
I setup a wiki page that anyone with an account on SIP SIMPLE client SDK wiki site can edit here:
http://sipsimpleclient.com/wiki/LinuxAudioCpuProblem
Please edit the page with your details to try to make a summary that can perhaps help us narrow our searches for a solution:
