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.
can you point us to the alsa-info results then? It could indeed be a
completely different hardware, where you only have HDaudio support (no
I2S codecs), in which case you shouldn't need UCM.
