On your machine card 0 is HDMI, which is why amixer -c0 is empty.
amixer -c1 will show the chtrt5645 mixer settings.
There have been input related fixes to chtrt5645's UCM config recently.
This is the latest
version:http://git.alsa-project.org/?p=alsa-lib.git;a=blob_plain;f=src/conf/ucm/chtrt5645/HiFi.conf;hb=HEAD
Try copying that to /usr/share/alsa/ucm/chtrt5645/HiFi.conf

I tried this fix, after substitute HiFI.conf file and reboot the laptop,
sound configuration options changed, output sound still working, but input
NOT.
Something else to do ?
Thanks.
Apparently your laptop requires some special configuration for the mic
to work. There are a couple of different rt5645 UCM configurations
already in alsa-lib:
http://git.alsa-project.org/?p=alsa-lib.git;a=tree;f=src/conf/ucm;hb=HEAD
You can try playing with "alsamixer -c1" to find out what settings need
to be changed. If you manage to find a working settings, then the UCM
configuration can be fixed.
I'll add Hans de Goede to Cc in case he has any hints or is otherwise
interested (he has fixed input for some other laptops that use rt5645).
I assume that when you say there is no input sound, you mean that the
microphone build into the laptop is not working ?
It could be that your laptop is using a digital mic rather then an analog one.
To try for a digital mic on the 1st dmic input, copy:
git.alsa-project.org/?p=alsa-lib.git;a=blob_plain;f=src/conf/ucm/ASUSTeKCOMPUTERINC.-T100HAN-1.0-T100HAN/HiFi.conf
To /usr/share/alsa/ucm/chtrt5645/HiFi.conf
*AND* put snd_soc_rt5645.quirk=0x0100 on the kernel commandline.
If that does not work you can also try:
snd_soc_rt5645.quirk=0x0200
snd_soc_rt5645.quirk=0x0300
snd_soc_rt5645.quirk=0x0400
There also is a second digital mic input, but there is no matching UCM file
for that, so you would need to edit the ucm HiFi.conf file yourself, or
play with alsamixer -c 1. To try and activate a dmic on the 2nd input try:
snd_soc_rt5645.quirk=0x1000
snd_soc_rt5645.quirk=0x2000
snd_soc_rt5645.quirk=0x3000

Hans
