Hi,

sending the mail CC to the mailing list again because I messed this up
last time. This is the output from 'alsaucm -c hw:0 set _verb HiFi'.

ALSA lib utils.c:261:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm2/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216/HiFi-dmic2.conf
ALSA lib parser.c:1190:(parse_verb_file) error: failed to open verb file /usr/share/alsa/ucm2/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216/HiFi-dmic2.conf : -2
ALSA lib main.c:960:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2
alsaucm: error failed to open sound card hw:0: No such file or directory
