Hi,
I am in the process of putting together a Class D amp with Khadas Tone Board DAC. I will be powerin gthe DAC with separate 5v PSU with enough grunt to power a RPI. The purpose would be purely to play files from another computer on my network using an app on my phone.
I have read that prior to RPI 4, there was some issues with glitches in the audio signal and that this was due to the shared USB and ethernet data bus on earlier models.
I'm not sure how common the issue is in practice, but am wondering if the issue would also exist if the RPI is connected to the network via wifi. I am looking at the RPI Zero W due ot price and size provided it will do what I want. A new RPI 4 seems like overkill and is quite a lot more expensive so would only consider it if it is my only option to avoid glitches.
Also, does anyone know what sized micro SD card I would need for Volumio or similar?
Thanks,
Mark
