Olivier,
I am certain that rtl8192ce does not disable interrupts for 2 sec, but I need
some more info from you.
What is your CPU situation? I suspect x86_64, but please confirm. How many CPUs?
What is the maximum CPU speed?
What distro?
How do you control the wifi? Is it NetworkManager? This is important because the
device driver does not initiate any scans on its own - scans are initiated and
controlled by upstream.
Please provide a URL for the test file sine.wav. If it is part of your distro,
then put it in a public repository, or E-mail it to me privately.
Larry
