>> Thanks Pierre. I'm aware of the work done previously on Asus T100. Not sure, if Asus T100TAM is any significantly different. Just tried your suggested commands as root user:
>>
>> # alsaucm -c bytcr-rt5640 set _verb HiFi set _enadev Headphones
>> ALSA lib ucm_subs.c:215:(uc_mgr_get_substituted_value) variable '${CardComponents}' is not defined in this context!
>> ALSA lib main.c:960:(snd_use_case_mgr_open) error: failed to import bytcr-rt5640 use case configuration -22
>> alsaucm: error failed to open sound card bytcr-rt5640: Invalid argument
>>
>> # alsaucm -c bytcr-rt5640 set _verb HiFi set _enadev Speaker
>> ALSA lib ucm_subs.c:215:(uc_mgr_get_substituted_value) variable '${CardComponents}' is not defined in this context!
>> ALSA lib main.c:960:(snd_use_case_mgr_open) error: failed to import bytcr-rt5640 use case configuration -22
>> alsaucm: error failed to open sound card bytcr-rt5640: Invalid argument
>>
>> I also tried this:
>>
>> # alsaucm listcards
>> ALSA lib utils.c:261:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm2/HDA Intel PCH/HDA Intel PCH.conf
>> alsaucm: error failed to get card list: No such file or directory
>>
>> There really is no such file "HDA Intel PCH.conf" in HDA Intel PCH directory, but I do not see any such file in the alsa-ucm-conf package downloaded from origin Alsa site.
