Jarkko-
Quick update. I was able to recompile the distribution kernel after a long wait, and with the changes that were made I was able to get some semblance of an audio device registered.
I've attached the dmesg.
$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: bytrt5640 [byt-rt5640], device 0: Audio rt5640-aif1-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0
I've also attached a screenshot of what I am seeing. No HDMI audio though, and when I attach a headphone to the speaker jack... I get nothing but very faint buzzing when I put my ear to it and hit 'test sound'
Thanks-
Tyler

Vinod,
Thank you for looking into this. I have attached the dmesg for this device. Please note I have tried kernels 3.16/19 4.0 and 4.1, all with same result. The attached dmesg file is from booting kernel 4.1/amd64: Linux mykro 4.1.0-040100-generic #201506220235 SMP Mon Jun 22 06:36:19 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux On Ubuntu 15.04
I can see these errors: [ 6.012196] (NULL device *): ipc: error DSP boot timeout [ 6.012386] byt-rt5640 byt-rt5640: ASoC: CPU DAI baytrail-pcm-audio not registered
Jarrko, can you see why DSP boot fails, perhpas some resources are missing/wrong
Very likely BIOS defines the DSP-host interrupt in another index what code is using currently. Could you try does changing irqindex_host_ipc from 5 to 0 help? Like how it is done here:
