Yeah, that should be feasible. Also, there is a "component" field assigned to the card. This is supposed to be referred by user-space as additional information. See snd_component_add().
Will add this to my ever growing list of things to do... :D
You don't have to :)
It's on Han's list.

I installed Ubuntu 14.04 to T100 and update the kernel to 4.5.0+ today, and I tested with a simple patch, which only added long_name in format "DMI_PRODUCT_NAME:card->name", and now in T100, command "cat /proc/sound/cards" will print 0 [bytcrrt5640 ]: bytcr-rt5640 - bytcr-rt5640 T100TA:bytcr-rt5640 Please find details below. I'll continue to add fw name. Or shall we use sysfs and snd_component_add instead?
