I got some new speakers (yay ). Said speakers only have an AES/EBU input. So, I want to switch from my current setup using the HDMI output of the Pi for 6 channels of audio to a setup using a 2 channel SPDIF output. I’m using an unbalanced/balanced transformer to convert SPDIF to AES/EBU. If there’s a direct way to go from i2s to AES, I’d love to hear about it.
I would like to have:
- SPDIF or AES digital output (24/96 or better)
- Ideally using the i2s bus
- keep some GPIO pins available
- analog audio input(s) (also 24/96 if possible)
- Work with volumio without too much fuss
My question is, what is what’s the best way to go?
I’ve seen plenty of USB to SPDIF converters around - do they sound as good as the i2s converters?
Can Volumio support audio inputs?
If I want analog and digital inputs and outputs, can I use the inputs and outputs at the same time? I want to read from the input, do some digital signal processing, then output to SPDIF (or AES).
Or just get a hifiberry digi and give up on having analog inputs ?
