Yes, I mean qemux86/x86_64 target kernel config, so that target kernel 
can use emulated sound card device to make some noise on host:)

I know there is something tricky to change the qemu target config as 
some internal tools are used. Last time, I hacked to add one extra 
config file including all changed entries. But forget it now:(

What's your suggestion for our kernel user to hack the config?
