If someone is still looking for a solution, this kext works perfect with Aspire 7720G including microphone (Clover): AppleHDA.kext. You need to install it to S/L/E replacing the original one. You also need HDAEnabler3.kext for ALC268.

Hey, I have the same notebook with same problems (sound and mic). You've provided links, but they are broken. Could you share files one more time? Almost 2 years passed...

You are right, the links are broken. See attached. Note that these kexts are not checked on Sierra, I use 10.11.
The procedure is basic:
1. Config.plist / Devices / Audio / Inject = (Audio_ID) 1
2. Place HDAEnabler3.kext in /Others
3. Disable SIP + Restart
4. Replace original AppleHDA.kext with the one attached
5. Terminal:
cd /System/Library/Extensions
sudo chmod -R 755 AppleHDA.kext
sudo chown -R root:wheel AppleHDA.kext
sudo touch /System/Library/Extensions
6. Enable SIP

Worked for me on El Capitan (10.11.6)! Thank you!

Good news! ALC268 is a rare thing and I am happy that it works. Just keep in mind that in case of any system update you will have to repeat steps 3 to 6.

Yeah, I understand this. I could find the way to communicate with you within this site, so, I have one small question regarding 7720g: have you shaped wifi card to get wifi internet working?

You can simply use app called EasyKext Pro (I used it). You should simply drag kext on its window and this tool will do all the installation automatically.
