Sorry it took so long to get back to you -- I've attached the following files:
cmi9739a-working-ac97.txt       - output from working */codec97#0/ac97#0-0
cmi9739a-working-ac97-regs.txt  - output from working */codec97#0/ac97#0-0+regs
cmi9739a-muted-ac97.txt         - output from muted */codec97#0/ac97#0-0
cmi9739a-muted-ac97-regs.txt    - output from muted */codec97#0/ac97#0-0+regs

attempting to write to ac97#0-0+regs with the following:
72 0001
0:72 0001
72=0001
72 = 0001
0:72 = 0001
met with the error:
-su: /proc/asound/card1/codec97#0/ac97#0-0+regs: No such device
