Hello everyone!

Please tell me how I can connect the spdif input to the ADAU1701? Is it possible?
How can I decode the data received from the spdif input using dolby/dts 5.1 and feed it to the output?

Thank you very much for your help

Hi!
The 1701 doesn't have an SPDIF receiver nor an SRC, both of which you'll need to use an SPDIF input.

You will need to add them externally and feed the 1701 the I2S signal. There are multiple ICs on the market that are a combination of SPDIF receiver and SRC.

For Dolby you'll need to be a licensee, which I assume you're not, but even then I don't know if the 1701 can handle it.
