Nearly every ADC and DAC chip uses I2S as the transfer protocol, unless it is a large multichannel chip, in which case it probably uses TDM, which is just the 4 or 8 or 16 channel version of I2S. Very odd that you could be working on audio hardware and not come across I2S. > My main concern is that I need more than two input channels and at least > one output channel. You either use multiple I2S connections, or you use a mode which supports multiple channels. I think the multichannel configuration is in the Sitara processor (BBB) documentation as McASP or something similar. Look in the ALSA tree in the SoC drivers to see if there is a driver for Am335x or Sitara. Might only be two channel, I haven't had a chance to check yet. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
