Did you guys check out the link below? I tried playing around a bit, but I just don't understand this stuff enough. In my digging around this looked to me to be the most promising. Apparently they've got this workaround to re-enable audio after waking from sleep with EEE PC's running OS X. Maybe a similar approach can be fashioned to work with our Mini's?
http://ipis-osx.wikidot.com/forum/t-100 ... l-speakers
Specifically the bit:
1. Install the AppleHDA.kext from the AppleHDA269from268 folder in Hagglebeef's zip (potentially unneeded, please leave feedback as per codeye's request)
3. Run the AzaliaAudio installer
If sound goes down with sleep or reboot run the following commands (please change the memory address to that found in Ioregexplorer for your eeepc - mine (codeye's) is 0xf7db8000 EEEPC901) - You need to have reggie_se installed from the developer tools:
This sets the verb command to turn EAPD on for the speaker Pin Complex:
sudo reggie_se -D PhysAddr -w 0x01470c02 -a 0xf7db8060 -B 32
This sends the verb command to the codec:
sudo reggie_se -D PhysAddr -w 1-a 0xf7db8068 -B 32

I think the amp isn't being turned back on after sleep. I hadn't thought to check the mic.. That confirms that the audio codec chip is functioning after sleep. It just doesn't seem to be giving any output, muted or amp off... Sure seems like reggie poking at just the right place with just the right command would fix the problem.. But yeah, the key is figuring out what that magic command happens to be..
