Audio amplifier device: Rotel A - 14 MK II certified ROON
Streaming device: PC : Intel NUC 12 i5
PC-USB device link
Good morning.
This morning when I connected my stereo to a ROON certified Rotel A - 14 MK II amplifier I saw that in the signal path it does not appear as System Output what until yesterday appeared in System Output the Rotel amplifier has disappeared. I have reinstalled the USB driver on the PC I use for transmission which is an Intel NUC 12 i5 but the ROON software still does not see the ROTEL amplifier connected to the PC via the PC-USB connection, entering the configuration of the output device and loading the default values still does not see the ROTEL amplifier. It has been working correctly for months
Any idea how to solve my problem?
Thank you very much?
Since the A14 isn’t connected to the NUC, make sure you have enabled system output on the other PC where the A14 is connected. If necessary, install the driver on this PC, too.
I don’t quite understand what you want to tell me. I attach my configuration.
If you wish, I can give you access via TeamWiever to my Intel NUC where the ROON software is installed.

The two pictures you wanted to attach to the last post did not come through.
Just a couple of questions to help support:
Just to be clear, the NUC running RoonServer is on a Windows OS or Linux OS? What is the OS on the NUC?
When you say “PC-USB” device link do you mean just a cable, or, something else. And if something else can you specify make/model?

I interpreted your OP to mean the streaming device and Roon core were separate computers. Please provide the clarifications, and missing images, requested by @Rugby. Thanks.
Hello again. Regarding your questions the Intel NUC uses Windows 11 operating system I don’t have ROON Server everything runs on the Intel NUC with the ROON software for Windows which I downloaded from your WEB . the Intel NUC is linked by a single USB 2.0 cable towards the Rotel A14 Amplifier. Today something must have happened when starting Roon now after looking at the audio configuration I disabled the System Otput and enabled Rotel PC-USB Audio 2.0 Wasapi and I could already find the Rotel A14 amplifier.
But there is something different, before in Signal path I could see that a conversion from 24bit to 64bit was done and later in the flow it did again a reverse conversion from 64 bit to 24 bit, this does not do it anymore and I do not know if it is correct or something happened ?
Thank you for your help. Apparently it is working correctly but the doubt I have is because before this incident occurred in the Signal path flow there was a conversion for example when the track was 24bit it transformed it into 64bit and at the end it passed it back to 24bit and now this does not happen. I don’t understand this
You might have had some volume leveling, upsampling or other DSP active. Roon goes to 64 bit to do its calculations in those instances and then moves it back down.

The conversion you mention was probably a bit-depth conversion, i.e. 16 bit or 24bit to 64 bit floating. This is used to retain accuracy when applying DSP. This could be for volume levelling or re-sampling.
