Hello, there is no sound working via speakers or headphones jack on Asus T100TAM. Sound works correctly via HDMI or Bluetooth headphones. The chip on this Baytrail machine is correctly recognized as bytcr_rt5640. From dmesg: bytcr_rt5640 bytcr_rt5640: quirk DMIC1_MAP enabled bytcr_rt5640 bytcr_rt5640: quirk realtek,jack-detect-source 3 bytcr_rt5640 bytcr_rt5640: quirk realtek,over-current-threshold-microamp 2000 bytcr_rt5640 bytcr_rt5640: quirk realtek,over-current-scale-factor 1 bytcr_rt5640 bytcr_rt5640: quirk MCLK_EN enabled bytcr_rt5640 bytcr_rt5640: snd-soc-dummy-dai <-> media-cpu-dai mapping ok bytcr_rt5640 bytcr_rt5640: snd-soc-dummy-dai <-> deepbuffer-cpu-dai mapping ok bytcr_rt5640 bytcr_rt5640: rt5640-aif1 <-> ssp2-port mapping ok input: bytcr-rt5640 Headset as /devices/platform/80860F28:00/bytcr_rt5640/sound/card0/input17 After bootup, kernel log is filled with: "Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port" messages. I do understand this is due to the missing UCM profile for the machine. I've successfully uploaded the output of alsa-info.sh. I'm on Arch linux, with latest alsa-ucm-conf 1.2.1.2 which seems not to be sufficient to make sound working on this thing. Is there anything I can provide to help smart Alsa people to help with this?
