Hi Daryl.

Did you have to set model options for snd-hda-intel on your T61 so as to get 
the sounds working? I ask because the ALSA-configuration.txt file for the 
1.0.16 alsa driver shows 3 options for the AD1984 codec, as below.

AD1984
   basic  default configuration
   thinkpad Lenovo Thinkpad T61/X61
   dell  Dell T3400

Perhaps your Thinkpad had sounds working out of the box, as per the "basic 
default configuration" above. Although saying that, there is a specific model 
option for the Thinkpad T61.

Would you confirm if you had to set a specific model option for the 
snd-hda-intel module in /etc/modprobe.d/alsa-base, so as to get sounds 
working, as below.

options snd-hda-intel model=thinkpad

Your lsmod | grep snd-hda-intel, shows the snd-hda-intel module loaded, yet 
Kyle's lsmod | grep snd-hda-intel, shows a different module, mainly 
snd-hdsnd-hda-intel, as you can see from his post. I can't find any reference 
to this module, and running modinfo as root for snd-hdsnd-hda-intel, shows no 
such module, but in his case this module is loaded. All a bit bizarre. I've 
asked on the alsa devel list about this module, but no replies yet, due to 
the holidays perhaps.

Thanks for your reply, and best wishes.

Nigel.
