Try to find an HDMI audio extractor with analog outputs. Something like this: https://www.amazon.com/Extractor-Decoder-Amplifier-Converter-Headphone/dp/B08814TNGF . Then use RCA to 1/4" patch cables to connect the analog outputs to your active monitor inputs (https://www.amazon.com/Hosa-CPR-202-Stereo-Interconnect-Meters/dp/B000068O17/)
