Internal Mic CX20590

[Noispirit]

Hello!

 

I can't get my internal mic to work in a Lenovo G470 with CX20590 audio chipset. I used Mirone's AppleHDA Patcher to get speaker and both jacks working but this tricky mic won't do any good.

 

I already calculated my codec verbs and pathmaps thinking it could be a specific problem from my laptop but they were the same as generated by patcher. Internal mic pathmap should be 20 - 23 - 26 as you can see in codec_dump with audio selector 24 and audio input 21 also associated but not used by the internal mic. Already tried different combinations to see if I managed to fix it. Instead, All I hear is some cracking noise output when recording and glitchy sound detection from sound pref panel.

 

I already checked command verbs and tried both Patcher and mine. Both works for everything except Internal Mic. I have no clue what could be. Internal Mic is working as I just tried with VoodooHDA but I need HDMI Sound and VoodooHDA does not support my HD3000 Any help I would be grateful.

 

my verb commands: 

01971C10 01971D10 01971E21 01971F04 
01A71C20 01A71D10 01A71EA0 01A71F95 
01B71C30 01B71D10 01B71E81 01B71F04 01B70C02 
01F71C40 01F71D01 01F71E17 01F71F90

 Thank you!
