Is there a way to fix this? Software or hardware wise?
Are you able to measure the MCLK frequency of the HDMI board? It is possible to run the ADAU1701 off it.

If I need an oscilloscope, then I am out of luck as i don't have one.

If there is another way, I can try it.

You really should have an oscilloscope if you are doing the kind of stuff we are talking about now. It will make your life much easier. Just as essential as a DVM for electronics work.

I suppose you could remove the crystal from the ADAU1701 board and use MCLK from the HDMI board instead. Default HDMI board MCLK maybe 256Fs and if that fails setup for 384Fs. The PLL mode pins only give 4 options and there is every chance the HDMI board MCLK frequency is within that range of 64Fs to 512Fs.
