How would you connect a Raspberry Pi to an Opus. Problem being there is no master clock from the Pi.

I've been wondering this as well.

As I understand it, it is possible using the Cronus clock.

However, there is also the Hifiberry Dac+ pro which contains 2 clock chips and provides i2s out with master clock. According to the documentation
Quote:
There are 5 pins carrying the following signals:
1 GND
2 Master clock (22.5792MHz for 44.1, 88.2, 176.4 kHz sample rates, 24.576MHz for 48,96,192kHz sample rates)
3 Bit clock (frequency = 32/64* sample rate)
4 Frame clock (frequency = sample rate)
5 Data


Would this work?

Yes the Dac+ Pro works very well. Have had it up and running for a couple of months and am very pleased with the results.
