Problems with 82801CA/CAM AC'97 Audio Controller on Evo N800v
Hello!
I have Debian unstable on a Compaq Evo N800v, lspci gives
(important line:)00:1f.5 Multimedia audio controller: Intel Corp.
82801CA/CAM AC'97 Audio Controller (rev 02)
But I'm not able to hear sound. I've installed ALSA, lsmod shows

Another problem is, that I'm not able to boot the new kernel after
"make install" of ALSA.. If changed the config to contain no sound
but the "Intel ICH (i8xx), SiS 7012, NVidia nForce Audio or AMD
768/8112x" as module. Before, the version which still runs now, has
built-in "Ensoniq AudioPCI (ES1370)" and "Creative Ensoniq AudioPCI
97 (ES1371)"
What do I have to do?
Can anyone help me?
Cheers, Chris
