Liliniser Posted November 4, 2013 Share Posted November 4, 2013 Hello everybody. I have a problem while patching AppleHDA for my audio vt1802. I use a laptop which has below spec. Intel® Core i7-2670QM CPU @ 2.20GHzIntel Cougar Point HM65, Intel Sandy BridgeVIA VT1802Intel HD Graphics 3000 I followed great tutorials and now I have int. speaker, ext. headphone, ext. mic, and int. mic operating. Everything works just fine except that the internal microphone has super low sensitivity. At first, I thought it was not working bacause even thought it was listed on the SystemPreferences>Sound>Input section, the input level bar didn't show any response. But soon, I realised it does work because it showed reaction when I smashed on my laptop . So I concluded that the sensitivity matters. Now I'm looking for a solution to boost the int mic's input gain. What I've been trying are 1. add <key>Boost</key><integer>3</integer> in the node of mic's in Platforms.xml ==> no effect (one funny thing is that the ext. mic does have effect on this) 2. adjusting layout.xml 1) adding MuteGPIO in the Mic section ==> the entire sound lost 2) adding SignalProcessing properties ==> no effect (maybe some other changes exist but I didn't notice) [CodecVerbs]02471c10 02471d01 02471e17 02471f90 --> int. speaker02571c30 02571d40 02571e21 02571f02 --> ext. headphone02971c20 02971d01 02971ea0 02971f90 --> int. mic02b71c40 02b71d90 02b71e81 02b71f01 --> ext. mic (changed to line-in as you can see)02470c03 02570c02 --> EAPD stuff I'm frustrated and almost given up. This post is the last hope . Please shed a light on me guys. I've attached ioreg, codecdump, layout.xml, and platforms.xml. Sorry for my poor English!

Mirone Posted November 24, 2013 Share Posted November 24, 2013 Try this Kext: AppleHDA.kext.zip Link to comment Share on other sites More sharing options...
Liliniser Posted December 4, 2013 Author Share Posted December 4, 2013 Unfortunately, it doesn't work because of the MuteGPIO thing. When I remove that MuteGPIO, it works like a charm but int. mic is still the same. I assume that VT1802 is somehow not fully compatible with AppleHDA. I appreciate for your help Mirone. Cheers!

Mirone Posted December 4, 2013 Share Posted December 4, 2013 Try MUTEGPIO = 0 rather than remove it Link to comment Share on other sites More sharing options...
Liliniser Posted December 15, 2013 Author Share Posted December 15, 2013 Tried setting MUTEGPIO to 0 but still the same problem.. Again, thank you for your help ^^ Link to comment Share on other sites More sharing options...

Liliniser Posted April 26, 2014 Author Share Posted April 26, 2014 Hello lazzy. Unfortunately, I don't own this laptop any more. But you can refer a couple of sites for that audio chipset. Please have a look at below links. 1. https://github.com/maxfierke/Lemu4-Hackintosh-Config/tree/master/vt1802p_devel 2. http://www.osx86.net/files/file/3934-applehda-via-vt1802p-1092/ I hope you get what you need.
