Lenovo Ideapad S740 requires quite a few COEF setups to make its speakers working. The verb table was provided from Ryan Prescott as the result of investigation via qemu: https://github.com/ryanprescott/realtek-verb-tools/wiki/How-to-sniff-verbs-f...

I believe that this sequence contains I2C writes to amplifier chips. It would be really helpful, if Realtek can provide more information for the I2C master interface for their codecs (describe basic I2C I/O).
Indeed. Already a few drivers need the initialization of the chip behind HD-audio, and it'd be good if we have some standard interface for that.
thanks,
