Problem: In the ALSA section you are told to emerge media-sound/alsa-driver which is good. But something needs to be stated... If you recompile the kernel you NEED to emerge media-sound/alsa-driver again to get ALSA working. Fix: Note: If you recompile the Kernel you must emerge media-sound/alsa-driver again so that your new Kernel recognizes ALSA modules.
*** Bug 7035 has been marked as a duplicate of this bug. ***
Bug 7035 is not a duplicate to this bug. One deals with recompiling ALSA drivers after recompiling the kernel. The other deals with Making sure your sound drives are compiled as modules in the kernel. Very different... That's why I filed the bugs separately.
Fixed in the 1.4 desktop guide. //ZhEN
