No sound from internal amplifier

Hi,all.

I moved from Ubunt to Arch yesterday, Everything works well
except that I can not hear any sound from internal
amplifier. Anyway, the headphones works well,

I used OSS. The amplifier functions well when I on Ubuntu,
So it can't be a hardware problem,  I think.

Here is some data, hope helpful:

During osstest, I can hear sound from pcm0, pcm2,pcm3, all through headphones. But no sound from internal
amplifier.
