OMG this kext has finally fixed the first loud click sound after startup for my alc665 with the setting FixType=3. And I don't know why codeccommander.kext can't solve the first loud pop sound issue.

A loud click sound just once after boot.

Make sure CodecCommander.kext is loaded.

I just have tested a simple method for alc665 to fix the loud click/pop sound ( AppleHDA 2.5.2 ) occurs at 10.9 when system starts up. A simple example here : 1. Put the CodecCommander.kext into Extra/Extensions(chemeleon) or /EFI/CLOVER/kexts/10.9 (clover) (don't install to sle) 2. Remove the 01470c02 or 01570c02 from the verbs. 3. /Library/LaunchDaemons/com.CodecCommander.plist <dict> <key>Label</key> <string>com.CodecCommander</string> <key>Program</key> <string>/Users/your username/Documents/LoginItems/CodecCommander</string> <key>RunAtLoad</key> <true/> </dict> 4. ~/Documents/LoginItems/CodecCommander #!/bin/bash kextunload /EFI/CLOVER/kexts/10.9/CodecCommander.kext sync sleep 15 kextload /EFI/CLOVER/kexts/10.9/CodecCommander.kext sync exit 0 5. Set root:wheel sudo chown root:wheel /Library/LaunchDaemons/com.CodecCommander.plist ~/Documents/LoginItems/CodecCommander Now the loud click/pop sound disappears.

alc665 the same loud pop sound at startup

Edit: Same pop sound as Dolnor's fix after some tests. ---------- My patched applehda for ALC665 works fine now, with just a tiny pop sound at every startup. Dolnor's fix does work either but with a very loud pop sound at every startup.
