Thanks for your reply.
I have found the DSP page, MIX page and sound control panel. I don't know if there is something wrong with my Settings, the device still has no sound. I connect the rme9652 to the ada8000 through two optical fibers, and then connect the headset. I can see in the MIX program that there is a channel entering signal and then flashing, but no output signal

Are you sure your pilot headset microphone needs phantom power 48V ?

typical headsets mic are for 5 V
Please check headset manufacturers infos.
Then the Mic gain needs to be open a lot, on the photo it is closed.

In the windows sound all ports are disabled, why ? can you enable those ?

@ramses the HDSP 9652 doesn't have Steadyclock yet.

@xuxin, "my sound card does not output any sound" is unclear. There is an output signal at 1/2, but that seems to be just the input noise routed to the output. There is no playback signal from the computer going to the card.

Indeed the ADA8200 works better with internal clock, the sync to external feature is the weak point of the device.
I own one, bought used for very cheap and it works better as clock-master.

Here the photo shows all input and playback devices in Windows Sound are disabled.
Do the WDM-devices need an extra configuration and enabling ?

This is the drive for thesound card.

It is true that the configuration of the 9652 is turned off, I am not sure which one to turn on, but I have tried to turn on all of them, but it will affect the output signal of the other sound card.
For the clock source, I don't know much about this, I will try to switch sources, and the headset gain issue, which I don't understand what is. I remember two months ago, this sound system was normal, after some time, it was the ada8000 broke, I replaced it, I am not sure if this will affect the sound card Settings.

v 3.3.6 from 2013 is "dog old" with the old version of TM. This I noticed already on the screenshot why I gave you a link of the latest HDSPe driver. We are currently at v4.4.8 with TotalMix FX from 2024 (11 years later!).

It should still work fine with the old driver, depending on the operating system.

Please test ASIO playback and look through Windows or search Google to see if you can find out how to enable these channels.

An ASIO driver (Audio Stream Input/Output) is a specialized driver technology developed by Steinberg. Under Windows, it allows audio software like DAWs (Digital Audio Workstations) to communicate directly with the sound card, minimizing latency (delay) and providing better sound quality.

Unlike regular drivers (such as WDM or Direct Sound), which often have higher latencies, ASIO delivers very low latency, which is crucial for tasks like recording or playing VST instruments in real-time.

Like for every other professional recording card RME offers for their recording interface high quality, rock solid ASIO drivers.

Did you buy the card used or do you have it already since longer time? I wonder that this topic appears to be completely unknown by you as this is very basic and fundamental for installing recording interfaces under Windows.
And it is also documented at the very beginning in the RME manual, see chapter 10:

https://rme-audio.de/downloads/hdsp9652_d.pdf
https://rme-audio.de/downloads/hdsp9652_e.pdf

Installing the ASIO driver is also needed to be able to perform a firmware upgrade on the card.
It is a good idea to use the latest firmware and the latest ASIO driver for "production".
If also a firmware upgrade proceeds without issues this is for me a good sign, that the card is accessible by the usualy upgrade tools and that you can write new code to the FPGA (the internal processor of the card which does "everything").

I will study the manual you sent in detail, thank you for your help.

I searched this folder for ASIO. But I still think it should be related to the channel being closed. Do you have any suggestions on which channel to test, or the Settings of DSP and MIX.

The operating system is windows7 Professional, and I don't know what the playback software is, but it will have a "SIMON" process when it runs. I remember that before there was no sound, we adjusted the knob of the ADA8000, and the Settings of the sound card were not changed

I checked Windows Audio and Windows Audio Endpoint Builder in Windows, and their status showed that they were running. By the way, I did a test in the afternoon, that is, the sound card of the environmental sound was not connected to the output device, and the 9652 was normally connected to the ada8000, and I connected the microphone and an active speaker to a channel separately. When I spoke to the microphone, the MIX software would show that there was an input signal in that channel, but no output signal.

I don't know much about DAW, but I do know that it has the function of exchanging audio information and is a digital audio workstatioc.The equipment I maintain is a flight simulator.

I would like to ask if re-inserting or replacing the sound card will clear the Settings or restore the default

I think not.
But from your 1st posting (see also RME last posting of your image) I see you have a lot of WDM drivers, that were disabled.
The WDM drivers are created by the RME driver settings under WDM.
Under the assumption somebody disabled the WDM driver in Windows you could try,
to delete them all and after that to recreate them, I am pretty sure that upon new creation they will have default settings again ( to be "not disabled").

Best is to make some notes or screenshots upfront, for which I/O port a WDM driver has been created.
Also document the Windows Sound settings for recording and playback devices.

Once you have documented that, set the number of WDM devices to zero ("0").
This deletes all WDM drivers for this card in Windows audio.
After that set it again to that number.
After they have been created freshly, they should be in the state active.
Then in the TAB speaker set the main sound device again to be a speaker device.
Finally in Windows audio make this speaker device to the default audio device for Windows.

I'm not entirely sure if changing the number of devices will reset that, but it's worth a try, I was thinking of that as well. You never know what Windows might want to remember...

Deactivated or disabled?

Hello, RME engineers, I still have the problem with 9652 sound card last time, we tested this sound card separately today, when I correctly connected ada8000 and ha8000, the mix program of the sound card worked normally, the microphone input was normal, the speaker output was normal, the input signal and output signal of mix program were normal, and the sound was normal. Here we can confirm that all hardware is normal, but when I connected the speaker of another sound card, the output of 9652 was no longer. I tried a lot of Settings, and I hope to get your help
