[SPAM] No ALSA device detected on ML403

Dear all

I am Binh, from Vietnam. I try to
use linux alsa driver on Xilinx XUPV2P board. This board has LM4550 AC97 audio
codec  same to ML403 board. 

  -I use EDK 9.1i sp2

  -I also use opb_ac97_controller_ref_v1_00_a
as requirement in ml403-ac97cr.c

  -I connect both Playback_Interrupt and
Record_Interrupt to Interrupt controller

  -I use ELDK as cross compiler, and download
kernel from xilinx.wikidot.com 

  -I config kernel: device drivers->sound
card support->Advanced linux sound architecture-> Generic sound devices
-> Xilinx ML403 AC97 controller reference

(I combine kernel and alsa
driver into one kernel file)

But when I boot the board there are messages: 

   " Advanced Linux Sound
Architecture dirver version 1.0.20

      Alsa device list:

No soundcards found"

Do I miss any steps?

Thank in advance

Best regards

Binh NT
