cht-bsw-rt5672 not working

[t-moe]

I downloaded the files from cht-bsw-rt5672 and copied them to /usr/share/alsa/ucm
afterwards i ran

alsaucm -c cht-bsw-rt5672 set _verb HiFi set _enadev Speaker

which gave me

ALSA lib utils.c:67:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm/GETAC-T800G2--T800G2/GETAC-T800G2--T800G2.conf
ALSA lib parser.c:1421:(load_master_config) error: could not parse configuration for card GETAC-T800G2--T800G2

@t-moe, did you ever get this working?

I too am trying to get audio working on the Getac T800G2 tablet and saw the same thing as t-moe did.

Here was my alsa debug script output:
http://alsa-project.org/db/?f=16eb1e700f8ca3cd948b661f73c9eeeff409cd75

I first added downloaded and added the ucm files/directory for cht-bsw-rt5672 which didn't work.

So, I copied over the ucm files/directory for cht-bsw-rt5672 with the the name it is expecting:

cd /usr/share/alsa/ucm/
cp -arp cht-bsw-rt5672 GETAC-T800G2--T800G2
cd GETAC-T800G2--T800G2/
mv cht-bsw-rt5672.conf GETAC-T800G2--T800G2.conf

Now the alsaucm command shows:

alsaucm -c cht-bsw-rt5672 set _verb HiFi set _enadev Speaker
ALSA lib main.c:438:(execute_sequence) unable to execute cset 'name='media2_in Gain 0 Switch' off'

ALSA lib main.c:1698:(set_verb_user) error: failed to initialize new use case: HiFi
alsaucm: error failed to set _verb=HiFi: Device or resource busy

I get some of this in syslog:

I'm not sure why the rt5670 driver is doing stuff when we have the rt5672.

Doing modinfos on both of them shows:

Do I maybe need to remove the rt5672 alias from snd-soc-rt5670 ?
Is there a quirk that I need to pass to the kernel for snd_soc_sst_cht_bsw_rt5672 ?
