I am writing to you because unfortunately I have exhausted my search and I am unable to get ALSA sound working on my Baytrail minipc. My dmesg only reports that: byt-rt5640 byt-rt5640: ASoC: CPU DAI baytrail-pcm-audio not registered aplay -l rightfully says there are no sound cards as the driver is not registered.
Can you give more details of your, does this enable HDA audio or I2S audio?
I have acquired the firmware file from the chromium repo here (https://kernel.googlesource.com/pub/scm/linux/kernel/git/firmware/linux-firm...) as was directed by the OP in this forum post: http://ubuntuforums.org/showthread.php?t=2254631
But unfortunately it seems the driver is still not loading correctly, even on Ubuntu 15.04 with ALSA 1.0.28
Do you have dmesg for us to look at so that we can see what might be going wrong
I see on gmane you are working on Skylake driver, could your work there possibly be backported to the Baytrail/RT5640 chipset?
No they are entirely different hw, so it will not work. We have uostream BYT driver and they should work
