Hi right now i did only one test:
On sender and reciver i use audacity to generate 1000Hz signal and to
capture it for measuring.
For microphone i use logitech c905 webcam. Distance between right
speaker and mic is 24cm.
Windows and Linux was configured for maximal volume. On linux i use
maximal alsa volume, not pulse. On windows no plugins are used.
Windwos 7 64bit, latest realtek driver.
Ubuntu Linux 13.10, kernel 3.12.0-031200rc6-generic.
Both Windows and Linux have same volume. Check attachment in audacity.
Reported issue may be result of enabled compressor plugin on windows.
I will need some more time to test in on UX31A, there is no windows on
