Dear L-Team,
did you try enabled audio debugging yet (as per [1]) and having a look
at its output? This might shed some light on the issue. Please note that
we have a changed a lot with regards to the audio architecture, so there
might be some ADC / DAC nodes which now do different internal routing
and therefore need a different (driver) setup.
HTH,
Andreas
