SGTL5000 concurrent operations

the SGTL5000 accepts the following inputs:

  • Line input
  • Microphone input, with mic bias
  • Digital I2S input


the SGTL5000 supports the following outputs:

  • Line output
  • Headphone output
  • Digital I2S output


Is it possible to use simultaneously inputs or outputs? For example:

  • operation 1: mp3 play from LINE_IN to LINE_OUT
  • operation 2: voice from MIC to Headphone.


Can I use LINE_IN and MIC as the same time? ¿Do I need a sound server, like PulseAudio, in linux o ALSA driver is enough?
