Dell E5470 Mojave install shows only 7MB VRAM[Solved] and microphone does not work

[hackmacnewbie]

Hi,
I have successfully installed OS Mojave on my Dell E5470 laptop with Intel 100 series chipset,I7 6820HQ processor, Intel HD530 graphics. What works - Track pad, Ethernet, WiFi through external dongle, Audio and camera. Whats's not working- Bluetooth, SD card, HDMI, Graphics acceleration. I tired various config files but I have not been able to resolve the issue, I tried the suggested ig-Platform id of 0X19160000 but I get a kernel panic on boot. The only id that allows me to boot is 0X591b0000 but I get only 7 Mb of VRAM and no acceleration and I cannot run iMovie. I have attached my EFI folder. Can you please lead me in the right direction?

Update - I managed to fix the issue by following https://www.insanelymac.com/forum/topic/334899-intel-framebuffer-patching-using-whatevergreen/ and updating lilu.kext in S/L/E folder to the latest version. Now I have 2048 MB showing as VRAM. However the HDMI port does not work. Can someone suggest any fix for that.Also, I have this issue of audio stopping after the screensaver starts. Then it works after restarting. Mic also does not work.
