I get understandable but not high quality sound but the Microphone  
does nothing and doesn't appear with the mixer.

I am using the snd_hda kernel module on an Acer 5520/5679 laptop with  
the following general info:

from dmesg:
pcm0: <NVidia MCP67 High Definition Audio Controller> mem  
0xf2680000-0xf2683fff irq 21 at device 7.0 on pci0
pcm0: [ITHREAD]
pcm0: <HDA Codec: Realtek ALC268>

 From pciconf -lv :
pcm0 at pci0:0:7:0:        class=0x040300 card=0x01261025 chip=0x055c10de  
rev=0xa1 hdr=0x00
     vendor     = 'Nvidia Corp'
     class      = multimedia

uname -a:

Any suggestions for getting the Microphone working,
