Actually the burst mode stuff has been done with TLV320DAC33, though more for power consumption reduction than for reducing RTT.
should not be interpreted as samples. If ALSA had a simplified API for byte streams sent over a serial output, we would have no problems using it and of course ASOC would be used then.
Non-audio data in-band is more of a problem, though, as is data that doesn't at the end of the day map down to periodic data.
