You could also try setting ALSA output mode to Direct (hw) in Audio Config but if that does not resolve the issue then it could be that the Linux USB audio driver in the kernel used in moOde 7 is not compatible with the USB receiver in the audio device. A newer Linux kernel may resolve this.

Is it an A12 (with the Woolfson chipset)  or A12 MK2 (with the Ti chipset) ?

To be honest, I do not know I reckon new one as I bought it a year ago, but I need to check it.


And it is A12 with Woolfson chipset. Is it bad or good?

Have you thought about making moOde standalone package that could be installed on Ubuntu or maybe just migrate to ARCH Linux which has the latest kernels and drivers? Debian is very outdated in that matter, so not so multimedia too.

@DRONE7 you gave me some thinking and I google out this:

https://www.horus.com/~hias/cirrus-driver.html

Might be handy but I do not know how if ever need to be implemented here.

Many in-house-brands ignore linux and use a low cost alternative... Wolfson have been problematic...:-(

However...you may be interested here.. though this refers to an I2S hat

You may be better advised to get some sort of Digi-HAT for the Pi and use the Coax/optical inputs on the Rotel ?

Upcoming moOde 8 is a Debian package but there is no free lunch when it comes to separating moOde the application from the underlying OS because of dependencies between moOde and specific versions of OS components and the custom patches we make to improve MPD and several kernel drivers. 

For the moOde project RaspiOS has proven to be an excellent OS for audio and offers he widest support for 3rd party software addon's many of which we use and are not available in other Linux distros like Arch.

Feel free to study the repos.
https://github.com/moode-player

The 8 release will also provide developer documentation that describes how to build and install the moode-player package (or any of the other packages) on RaspiOS Bullseye or optionally generate a complete ISO image containing moOde. You can incorporate whatever customizations and kernel version you desire using the new build tooling but you are on your own as far as testing and troubleshooting goes.

Hi Tim,

That sounds very well. It was just my thoughts. You are doing a great job. When I hopefully sort out my problem I will donate some money to help the project.

Cheers

Thanks, I am working along that way but still no luck. It seems that I loaded the driver but I can not pick it up by MoOde GUI, oh well I am too weak with Linux. I am amusing Bluetooth for now but I would love to use my PI4 to play my library. maybe Tim will come up with something in the 8.0 version.
