Hi [mention:dc11ece8204f479e8dce2a47a33b20d3:e9ed411860ed4f2ba0265705b8793d05] ,

Thank you very much for the information. It is a great help for programming my "-Q" boards.

Yesterday, I tested the audio code—provided by someone (https://forum.arduino.cc/u/ptillisch) on the Arduino forum—using the VentunoQ and the Media Carrier Board.
It works! That’s fantastic; it provides a solid foundation for further exploration.

aplay --device="plughw:CARD=monacogertrude,DEV=0" "/usr/share/sounds/alsa/Front_Center.wav"

If I understand correctly, this means the audio interface (the card) is named "monacogertrude." The Ubuntu operating system includes several pre-existing WAV files in the `/usr/share/sounds/alsa/` directory.
The command above plays the "Front_Center.wav" file.

The Media Board features a 3.5mm 4-pole jack for a headset.
The output is routed there; I assume `DEV=0` refers to the endpoint.

I was also given a command for recording audio:
arecord --device="plughw:CARD=monacogertrude,DEV=1" --duration=5 --format S32_LE --rate=48000 recording.wav

However, this doesn't work yet, as the command doesn't specify where the `recording.wav` file should be saved. It seems I need to create a folder and the file first and then include that path in the command.
I believe these two commands are a good starting point—along with digging out the appropriate driver from the system.
Now I have to find in a manual DEV=0, DEV=1.

In short: The Media Carrier Board and the VentunoQ are capable of communicating with each other.
This also means that the drivers from Arduino are not yet complete and are in urgent need of an update.

If I’ve understood correctly—and I don’t want to state anything inaccurate—there is also a mention on the Arduino forum that a dedicated "Media Carrier Board" is being developed specifically for the Ventuno-Q.
However, this would mean that "compatibility" is effectively a thing of the past.
Having one board for the UNO-Q and another for the Ventuno-Q doesn't make sense to me, especially since all the schematics and plans show the same connections—unless, of course, there is some additional circuitry required on the board for the Ventuno-Q.
Granted, the real difference lies in the codecs on the respective "-Q" boards, but the amplifiers on the Media Board would be identical.

This is the CODEC on the VentunuQ: MAX98091

Here is the correspondence:

Update:

The App Lab is actually 0.12.0 - I installed it yesterday.

There is also a new Ubuntu operating system image available that can be flashed onto the board—applicable to
both the UNO-Q, 20260528-558, and the Ventuno-Q, 20260729-248. I have the older versions.

How to flash the image:

https://docs.arduino.cc/tutorials/ventuno-q/flash-image/

However, I still have some concerns regarding whether the flashing process will go smoothly.

I am unable to install the "adb" command on my Ventuno-Q.
https://docs.arduino.cc/tutorials/ventuno-q/user-manual/#access-via-adb

When I attempt to install it, I encounter an error: "a module cannot be installed; it cannot be found."
The flashing process involves, among other things, the vendor ID (05c6); if this is lost during the flash, it must be entered manually.
https://docs.arduino.cc/software/app-lab/setup/linux/#step-2-configure-udev-rules

And after that we must install the App Lab manuell too.

...it is growing up to a hard work...

I've purchased two of the supported MIPI/CSI ArduCam, I'm waiting for the flashing until I received and testet this both cameras.

Well, this was my last few days.

Best Regards

Great to see new board. But I think media carrier board you will get it in the road test.
