We have connected audio Amp to i2c1 on probing in u-boot we can see the address 6E of audio amplifier , but could not find any android driver on Internet to control this device through i2c .
Audio amplifier device connector
Audio Codec CS42888 same as Sabreauto also on same cpu pins as Sabreauto
By default there is no sound when audio track is played .
I think we have to select channel and few other configuration is required to be performed for audio amplifier to work .
Is there a kernel driver required for this or ?
