Hello Geert, hello Lorenzo, Many thanks for your comments and for the willingness to help. For your information, we've recently discovered that, with all the findings already described being absolutely valid for the reference targets, disabling CPUidle on the customer HW is apparently not enough to fix the audio dropouts. We will first try to identify those differences (both HW and SW) which keep the issue reproducible on the customer boards. Once this is hopefully understood, we'll come back with feedback. This investigation also happens to overlap with my vacation. Hence I plan to update you on this topic in 2-4 weeks from now. Thanks again. Best regards, Eugeniu.
