I have no sound, may be two cards conflict? Help

I got a Acer Aspire 4738g with HD6370M. Everything is OK but Audio. alsamix seems recognize the cards but shows no channel. kmix shows channel Master, PCM, etc. but no sound at all.

$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
01:00.1 Audio device: ATI Technologies Inc Manhattan HDMI Audio [Mobility Radeon HD 5000 Series]

$ sudo aplay -l
**** List of PLAYBACK Hardware Devices ****

  Subdevice #0: subdevice #0

dmesg | grep snd

I think it may be two cards conflict. Can/How I disable the HDMI Audio? (no options in bios)

headphone output is correctly, only internal speaker has no sound
