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 https://www.insanelymac.com/forum/topic/293539-applehda-patched-successfully-but-int-mic-has-very-low-sensitivity/#findComment-1971014 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 https://www.insanelymac.com/forum/topic/293539-applehda-patched-successfully-but-int-mic-has-very-low-sensitivity/#findComment-1973630 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..

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. Thanks.
