When CPU MASTER was default, people asked for SLAVE. But nobody asked for MASTER since we selected SLAVE by default. Both work equally well, it just saves our efforts.
What were people actually complaining about? I suspect it was the root clock for the audio tree that they were concerned about rather than the I2S bus clock.
No complaints. I just get the task to do. I guess most quality conscious products can afford to attach a dedicated OSC to a good CODEC. A CODEC already specifies the clocks it support and usually comes with 'preferred' input clocks. So, just having a specified rating accurate enough OSC can take care of quality. On the other hand the clock sources on CPU side are not particularly accurate for audio-clock generation. Or so have I seen so far.
