[alsa-devel] My PC has 6GB memory but the limitation of the alsa-driver is 4GB.

The problem "Fedora 10 x86_64 alsa problem: Realtek ALC889A Audio
Codec(ATI azalia) not detected on alsa" seems solved.
I consulted #alsa on FreeNode. And Mr. Daniel Koukola discovered the
reason. He spared for 14 hours in all this evening and all this night
for my problem. Thank you very, very, much, Mr. Daniel Koukola!
