You will need downstream audioreach-topology & alsa-ucm-conf.
Install artifact of audioreach-topology to /lib/firmware/qcom/x1e80100/X1E80100-ACER-SFA14-11-tplg.bin. Seems that the generated X1E80100-ACER-SFA14-11.conf is not required?
Install alsa-ucm-conf/ucm2 to /usr/share/alsa/ucm2.
Invoke alsaucm listcards to see if configuration is detected.
Explicitly set UCM config by alsaucm set _verb HiFi.
Default volume level is very high, make sure to lower WSA WSA_RX0/1 Digital Volume and WSA2 WSA_RX0/1 Digital Volume to around 5(alsamixer) or 48(amixer).
Invoke speaker-test -D hw:0,1 -c 4 -t wav to test.
Explicitly enable microhone by alsaucm set _verb HiFi set _enadev Mic.
Invoke arecord -D hw:0,3 -f S16_LE -r 48000 -V stereo /dev/null to test.
Likewise, use speaker-test/arecord to test headphone jack and HDMI audio. Corresponding index and name could be seen in alsa-ucm-conf.
