@ivandrs, Since it is not ubuntu linux on your machine, I don't know how to build kernel for your distro. Please apply this patch to the kernel source, build and install the testing kernel. boot with "snd_hda_intel.dmic_detect=0", after booting up, please run alsamixer, please make sure master, DAC1 and DAC2 are all at maximum volume, then test speakers. And upload the alsa-info.txt with testing kernel.
