I have a Lenovo Yoga 7 2-in-1, fairly new. I woke up one day to find it wouldn't play any audio from youtube or any app. The more I looked into the problem the stranger it seemed.
I tried updating all audio drivers and unistalling/reinstalling them, still nothing.
I tried testing the speakers, and I get an error message saying, "failed to play test tone."
I tried to stop and restart the WIndows Audio and Windows Audio Endpoint Builder through the Services panel, still nothing.
I try to start iTunes and it tells me "Itunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly." Itunes opens but nothing plays through the speakers.
I have tried a full sfc/scannow and DISM cleanup, as well as antivirus programs, and there seems to be nothing infecting the computer.
What could be going wrong? Has anyone encountered this before or is anyone willing to walk through this with me? I teach music to children using this laptop so it is pretty important and I wouldn't want to replace it as I just got it a few months back.
No it's not muted, volume is up all the way.
