Headphones stopped working after driver update.
Lenovo G50-70, Conexant Smart Audio HD, Win 10 Home 22H2.
I updated the audio driver to try to fix a problem with output on HDMI device, and the laptop headphone output no longer works. The sound troubleshooter says that it can't find the problem. The OEM driver still works for the laptop audio, but not for the HDMI monitor/TV.
