If you're having issues with
auich(4) after resume, you should file a bug report.. or at least send the question to the bugs@/misc@ mailing lists.
As for restarting the "sound server", if you're not running
aucat(1) in server mode, then there is no sound server.. if the audio driver simply doesn't work after resume, no amount of user configuration will fix the problem.
This laptop is probably older than what's being currently tested these days, from the dmesg it seems you're using
apm(4), consider disabling that in UKC/
config(8) and seeing if
acpi(4)-based suspend/resume works.
Trying a 4.8-current snapshot may also be worthwhile.
