Intel ICH4 audio troubles

    Hello,

    I've been having trouble getting audio working on my system, which 
is 5.1-BETA (built last night).  I have an Asus P4PE-L motherboard with 
onboard audio, which uses the Intel 82801DB chipset with an AD1980 AC97 
codec.  The kernel reports no problems but I can't hear any audio.  
Here's the dmesg output:

And, in case this is of any use:

muscle# sysctl -a | grep snd
hw.snd.targetirqrate: 32
hw.snd.report_soft_formats: 1
hw.snd.verbose: 3
hw.snd.unit: 0
hw.snd.maxautovchans: 0

Thanks for your help.
