It will playback from speaker in the first 2 seconds, then switch to headphone. Steps to reproduce this issue:
- plug out headphone and playback a wav.
- stop playback and wait for at least 5 seconds, then plug in headphone and playback a wav.
I'd really like to understand the logic behind this in more detail - what is the actual problem here and how does this fix it? You're moving the clock management from the bias level setting to the stream startup and teardown which doesn't seem directly related, if anything it seems like it'd be making things worse since it reduces the proportion of the time where the clock is enabled. My guess is that the jack detection needs MCLK enabling.
