I've also upgraded firmware and didn't notice anything strange on linux and windows.
Thank you for confirmation!

Lorien, what is the best way to detect DSD signal on waveio's pins, in order to switch dac mode? Can I use LED pins for that?
I'm working on it but for now I'm trying to make the LEDs to display the sample rate in a 'stable' form. After it's finish I'll make WaveIO to output a signal for DSD / DoP mode!
Actual firmware does not show you when DSD / DoP is enabled (for now)!
What signals do you need and on what voltage level should be active (High/Low)?

Great! High 3.3 or 5v will be ok. Anything will work actually as I'm using gpio. If you don't have physical pins available combination of multiple pins is also fine.

I cannot send 5V signals out of XMOS processor since the I/O buffers are working with 3.3V.

We'll see how it goes! I was considering the same option since all the 1-bit signals are "taken" by the PCM LEDs (and those aren't all!) so combination of pins is a fastest solution to this problem.
I'll announce here when a beta firmware is available for testing!

Hi, I recently bought a music server that has the waveIO card. The I2S output is currently wired to a SPDIF port (on an available PCIE slot). When I connect it to my DAC COA input music plays well over PCM but I cannot play DSD at all. My DAC does have however a I2S input which should in theory allow me to the connact the card to it with full DSD support.

The PC is currently running Audiolinux and used as a Roon end point.
Is there a way I can connect the card to the I2S input? What do I need to change?

@ al2813: Hi there! If I understand correctly, you want to connect the I2S bus of WaveIO to the I2S port of your DAC? I'm right? :o

Hi, yes this is exactly what I want to do. not sure if this is possible after reading a lot of material over the past days...

it depends on what you wrote and your skills and will to do it! :)

I also have a board WaveIO and I want to connect it to i2s to the DAC board ak4497:

The DAC board has a connector for connecting an amenero. Is it possible? Where can I find connection information?
