Windows 10: HDMI switcher with audio extractor works with all devices except my laptop

Hello, I just bought a prozor HDMI 3x1 switcher with audio extraction. I connect a Google Chromecast, a ps4, and my laptop to the switcher, the output of the switcher is going to a monitor and the audio to speakers. The switcher works perfectly with all the devices, but when connecting my PC I get the image on the monitor but the audio doesn't go to the speaker as it does with the other devices. I already tried to update audio drivers and nothing and when I see the playback devices it doesn't detect any output from the HDMI port.
