[alsa-devel] Recovering from DAI xrun condition

I see the ALSA framework is capable of detecting and recovering from ring
buffer xrun conditions. What I'm not sure about is whether it is possible
to recover from a DAI xrun error as well.
Let's take the example of an I2S interface operating in tx mode. If the
tx fifo overruns, one or more words will be discarded by the interface.
If an odd number of words gets discarded, this may result in the left and
right word being swapped. This is actually a quite common weakness in I2S
Is there a mechanism to notify the ALSA subsystem that a DAI xrun
condition has occurred?
