I repeated the test. I'm afraid I did a mistake in reporting the test results.
mainline 5.7 rc1: sound not working (the sound emitted is not intelligible, it's like an infinite echo loop)
mainline 5.6.0: sound working, Skype test not possible because wifi connection is not working
When I boot back to mainline 5.8.14 sound s perfect and wifi works as expected.
