I'm using a later kernel version but I think the basic configurations should still apply (i.e. same pins/same overlay/same cape) Gists here https://gist.github.com/ca8a33407cdef56cdb3e.git and here https://gist.github.com/1605ceb9c4565141cae2.git show slots and pinmux before and after loading the audio overlay. I'm getting a couple of odd messages in dmesg: [ 709.782296] davinci_evm ocp:sound: ASoC: CPU DAI (null) not registered [ 709.789827] davinci_evm ocp:sound: snd_soc_register_card failed (-517) [ 709.813163] davinci_evm ocp:sound: tlv320aic3x-hifi <-> 48038000.mcasp mapping ok Most importantly without an audio cape in place root@arm:/# speaker-test -D default:EVM appears to work. With a cape in place there are recurring error messages about buffer underruns as I reported here last week. In neither case do I see any obvious I2S activity. There is a tool set for I2C manipulation. It would be really helpful to have one for I2S!. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
