I have a HDA NVidia, with a Conexant chipset CX20549 Venice (CXT5045)

I tried to test the last alsa-kernel in -mm tree to support my mic. 
(2.6.21-rc4-mm1 and 2.6.21-rc5-mm2)

When I try to load the hda-intel, I receive this message:

Mar 27 11:29:08 dig kernel: hda_intel: azx_get_response timeout, 
switching to polling mode
Mar 27 11:29:09 dig kernel: hda_intel: azx_get_response timeout, 
switching to single_cmd mode

After loaded, the speakers doesn't work. Headphone works ok. Mic too.

Look in code, I apply this comment and now the speakers works for me:

But, I don't understand why, because this code is not executed for my
