How can I deactivate or deinstall DAX drivers I don't need?

Juergen · April 2023

When I tried to use DXLab's WinWarbler for RTTY I have seen a limitation of max 16 soundcards which can be selected. The selection of the 16 popping up in the menue cannot be controlled by the user. Unfortunately no DAX RX 1 showed up, it started with RX2, RX3 etc. Based on the proposal to deactivate soundcards I don't use at the moment I deactivated all DAX RX channels except RX 1 and RX 2 and IQ 1 and IQ 2 using the device manager. Even though I had deactivated those RX channels they still showed up in the selection menue of WinWarbler.

As a next step I deinstalled all those RX audio channels I don't use except RX 1 and RX 2 and IQ 1 and IQ 2 via the device manager, re-started Windows 11 and was surprised they were shown as active devices in the device manager and subsequently could be selected in WinWarbler. But again no RX 1 could be selected.

Question now is how to permanently de-install those devices I don't need or how to hide them in way that WinWarbler doesn't see them. If I need them I would re-install them again.

Any help would be nice. The proposal to use a different program for RTTY is not applicable for many reasons. Therefore I need to find a solution for WinWarbler.

Hello Martin,

after reading your response and sending mine I have re-opened the control panel again, disabled ALL DAX channels in output and input devices, re-booted my notebook, opened the control panel again and allowed the access of Windows and Apps to DAX RX 1 and RX 2 only. This step brought RX 1 into the selection menue of WinWarbler. I don't know why because there are still others which are not allowed, i.e. disabled. But this doesn't matter at the end. At least I have the system working now.

Thank you for your comment which brought me to perform another step with disabling all devices I did not do before. Problem is solved. But it is never a really good feeling if you don't understand the reason behind.

Thanks, 73

Juergen,

Did you follow the guide? - https://www.dxlabsuite.com/dxlabwiki/FlexSignature - This takes you through disabling the DAX Audio devices that you aren't using.

Hello Martin,

yes, I used the Wiki already. Unfortunately the German names of the different sections in Windows 11 Control Panel are different but I am quite confident that those are the right one for Playback: control panel (Einstellungen) - Sound - Alle Audiogeräte (all audio devices) which are separated into Ausgabegeräte (output devices) and Eingabegeräte (input devices). The output devices show the list of all DAX channels, and I have allowed the access of Windows or apps to RX 1 and RX 2 only. All others are not allowed.

When interpreting the Wiki properly I should have done exactly that what was suggested there. But despite this procedure (after a re-start the settings did not change) all those not-allowed RX channels still show up in the selection menue of WinWarbler. In addition I had also disabled the devices using the device manager (properties and then selecting disable or deinstall etc.)

Sorry for the long description but might be there is still a very low probability that I misunderstood the procedure suggested in the Wiki.
