Hi,

I'm tinkering on the wintron 7.0 together with Tobias Mädel and have tested your patch with your UCM config on Linux 4.5.0-rc2. It looks like we are getting somewhere. The soundcard is now being recognized by ALSA. But there are still some errors in that seem to be related to the audio driver. As soon as I try to output any sound I get an error: [ 88.906739] intel_sst_acpi 80860F28:00: fw download failed -16 [ 88.909262] intel_sst_acpi 80860F28:00: FW download fail -16 [ 88.948434] Audio Port: ASoC: no backend DAIs enabled for Audio Port

Does anybody have an idea why the sound chip is not responding and the fw download timeouts?

I've uploaded dmesg, lsmod and tree /proc/asound output here: https://github.com/TobleMiner/wintron7.0/tree/master/logs/4.5.0-rc2-ARCH-tsy...

It's very likely that you have a BYT-CR device where the BIOS folks modified the order of interrupts which causes the IPC/download issue. If this was correct you would also need to use the SSP0 interface since SSP2 isn't available on the BYT-CR package. I have a set of patches for BYT-CR that are still being worked on, i will try to share what I have shortly and could use some help to double-check them before sending them to Mark, I only have one BYT-CR device (ASUS T100TAF) which is not fully working.
