as far as I see I have similar chipset configuration but different video chip and usb web cam - I have Dell D520.
Have you assigned slots to the audio devices you are using. People reported success after doing this in similar situations.
CODE
cat /etc/modprobe.d/sound
## ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-usb-audio
## module options should go here
#options snd-hda-intel index=0 model=dell-m6,ref,auto
#options snd-hda-intel index=0 model=ref enable_msi=1
options snd-hda-intel index=0 model=ref
#options snd-hda-intel index=0 model=hp-dv5 enable_msi=1 position_fix=1
options snd-usb-audio index=1
This assigns same id to my devices.
Might help I hope!
The other thing I'm seeing in your issue is
CODE
ALSA lib conf.c:4633:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM hdmi
This is something about HDMI and I dont understand where it is comming from.
Arent you willing to try the 2.1 skype version it has many changes addressing newer hardware (such as hdmi and different web cams).
