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
Thanks. This commit for alsa-lib should fix this issue:

The patch doesn't help unfortunately. Deleting LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf still works with the patch installed. Can I help debug this somehow?
If you have latest alsa-utils, the command 'alsaucm dump text' should work, otherwise try 'alsaucm set _verb HiFi'.

Hi alsa devs,
I'm on Arch Linux on a rather uncommon laptop (Lenovo Miix 320) and my sound stopped working on the upgrade from alsa-lib 1.1.9 to 1.2.1. wabbits on IRC helped me track down the problem to a change in the /usr/share/alsa/ucm (now /usr/share/alsa/ucm2) files. It seems like /usr/share/alsa/ucm2/chtrt5645/HiFi-dmic2.conf and a symlink at /usr/share/alsa/ucm2/chtrt5645/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf were specifically added for this laptop but in the contrary they break the sound for me.
After the upgrade to alsa-lib 1.2.1 the sound is not working. The commands play no sound:
pasuspender -- speaker-test --nloops=1 --channels=2 --test=wav --device=hw:0,0 pasuspender -- speaker-test --nloops=1 --channels=2 --test=wav --device=hw:0,1And this is the alsa-info.sh output http://alsa-project.org/db/?f=f883910a5c5101b4b1ea4202d1fe84ccd139f796
After deleting the /usr/share/alsa/ucm2/chtrt5645/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf symlink both commands from above play sound and this is the alsa-info.sh output http://alsa-project.org/db/?f=e759eb9118a191b6c3b8c021fed58abc9cf95076
Thanks. I forgot to fix the file path in chtrt5645/chtrt5645-dmic2.conf . Could you test this patch?
