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 Regards, Hans
