RJ45 I2S. is there a way to measure if signal output works

Hello

I had to do a cable for I2S with RJ45 from my interface to my Aqua La Voce S3 dac
The signals from my interface are Data-BCK-WCK-MLCK. The Audio gd interface has a hDMI out so it is in balanced mode. I took the signal inside before the HDMI chip which takes unbalanced signal to HDMI balanced. There was 42 ohms in signal paths (Data-BCK-WCK-MLCK) that goes to HDMI chip. Il took them out to unload because I didn't want to feed HDMI chip. It was perhaps un necessary but... As it is, it doesn't work with the Dac.
Can I check with a scope if there is signal coming out of Data-BCK-WCK-MLCK ? MLCK is not used as I don't need it with R2R dac. The connections were checked many times and they are correct.
HL-MLCK- Dale are not used on RJ45.
