I manage to get everything to work on VoodooHDA. The 2.8.8 https://sourceforge.net/projects/voodoohda/. Similar to how it works on windows I just select a output. (Screenshot). I did have to make a few adjustment in the info.plist in the Voodoo kext to true. Before the volume buttons weren't working either was mute but the below fixed it.
"<key>VoodooHDAEnableMuteFix</key>
<true/>
<key>VoodooHDAEnableVolumeChangeFix</key>
<true/>"
@Insanely, If i'm not wrong isn't the Audio in E6230 HD93BXX?
