Hello, The problem is present with all kernels disponibles for my system :
5.0.0-29 4.15.0-65 4.15.0-20 In the evening I have to listen to music / movies on my headphones to avoid waking my child. This problem is very annoying, it hurts my ears, I presume that it is not good for my auditory system to hear such a sound (very high whistles). The problem is also present in Debian 10 Buster with kernel 4.19.0-6 Best regards.
