USB to I2S suggestions

[dougduck]

Has anyone tried using any version of Raspberry as usb to i2s?
Is it an alternative to XMOS?
What are the most viable alternatives today?

Thread 'USB UAC2+HID Multichannel input/output interface York'

Hello DiyAudio community,

TL;DR: This is a USB transport for audio output (up to 8ch) and input (2ch for now) and user device control (e.g., DSP management) from PC (MacOS/Linux/Windows) thru I2C/GPIO. Including bootloader for remote firmware update, flexible device configuration, HID interface, multiple audio output options, integration with SigmaStudio (simultanious audio playback and ADAU DSP configuration). Compact module available in USB-C and USB-B versions, isolated or non-isolated.

Latest docs, config tool, link to buy:

Most versatile, and probably the best solution on the market is jlsounds board. It can drive directly, or provide i2s. It's also very easy to supply with linear supply.

York can do it too 🙂 As well as multichannel TDM/I2S output, S/PDIF out, I2S 2ch input. Perhaps one feature that is not supported right now is the native DSD. Additionally it provides communication channel from PC to I2C.

It's not isolated. No addon board support for master clock. All done within one chip. Don't get me wrong, i'm following your thread diligently with great expectations, it's still young and i have no doubt it will grow into a very very good project.

True

No addon board support for master clock.

It actually supports that. In external clock mode configuration it would disable on-board oscillators and mclk pin becomes an input.
44/48kHz select signal is available on F0 pin.

Don't get me wrong, i'm following your thread diligently with great expectations, it's still young and i have no doubt it will grow into a very very good project.

Thank you 🙂

Sounds really cool! I'll read it! 👍

We are in a DIY forum, the intention is to develop ourselves and not to buy a product.
Even less so from this user, who thinks he is the king of the forum, and doesn't share any knowledge. 🤢
I've already developed with XMOS, but I'm looking for other alternatives too, there are some very creative and intelligent people! (like this project mentioned above)

Ooohh sorry then
