Sounds -> Microphone: 39 instances of DAX in various states

I couldn't get my PC (Dell XPS15 9550 Win10 v10.0.17134) to send the laptop mic audio to my 6300 so I had a look in the Sound -> Recording window. FWIW I'm using SSDR 2.4.9.

I took a look in the Sound -> Microphone settings and found many instances of dead and duplicate devices (as per screenshots 1-7, same before and after the rest of the steps described below).

I tried the previous instructions of going to C:\Program Files\FlexRadio Systems\SmartSDR v2.4.9\64-bit Drivers\* and clicking the 4 x uninstall .BAT links. Rebooting removed none of the extra drivers, about 10 still remained.

I therefore went to C:\Program Files\FlexRadio Systems\SmartSDR v2.4.9\64-bit Drivers\* and run the 4 x RemoveRegistryEntriesRemove Registry Entries .reg files and rebooted. All gone from the Sound -> Recording window at that point.

Reinstalled the 4 sets of drivers from the ...install.bat files. Rebooted. Didn't see any Microphone DAX entries at all.

I did get a message flash up about a file or folder. Videod it and it was about "A subdirectory or file C:\Users\MRQA Consulting Ltd\Appdata\Roaming\FlexRadio Systems\InstLogs already exists." Not sure if that is an issue or not but I thought I would mention it.

Went through each of the 4 sets of folders and clicked the Audio_DAXServiceservice.reg and Audio_DAX.reg entries. Rebooted.

Now I have 39 entries in the Microphone screen. Playback window looks fine (13 entries for DAX, as expected).

Now when I start up SSDR I get a DAX failure message before I even start up the connection to my rig (when on LAN). See screenshot 8.

In Device Manager I see an issue with the MIC entry, but the Audio inputs and outputs list looks correct. (screenshots 9 and 10).

No idea what to do next. Please advise.

It is selected. That's not the issue. I managed only once to get audio of the the PC to the rig. Now I can't get SSDR to load without DAX crashing.

Mike,

I feel the answers above have not fully addressed the problem.  You need to clean out the "bad" audio drivers and you may have to do some renaming.

This process will not only fix Dax if you are having driver issues with it but also will help programs that limit their audio driver list.

I have several programs that seem to think that there would never be more than say 10 sound devices so they simply do not display any past that.  Often times for me if I plug in say a USB mic it is well out in the list and some of the older programs will not see it.

In case you want to undertake this effort the process is not hard.  Follow this procedure:

Yes my Windows had the wrong default output and input devices. Changed now to the Realtek ones. Thanks for the reminder to check that.

Yes the issue is the duplicate entries.

While the duplicate entries are troublesome they should not prevent operation.  As long as the driver exist and can be found the PC should enable and Dax should work normally.

I will try to figure out how to remove the dups

Hi Mark,

I can confirm that the P/CW window no longer says PC (disabled). :)

Now passes audio (so long as I remember to turn DAX off. There seems to be a high base noise level but at least it picks up audio from the mic now when I "warlo").

So that's something :)

As I mentioned you need to select the defult sound device on the computer,,not DAX.
Check your conections to the mic, and if you have any computer EQ? could be the low end is boosted.
Mabe the mic gain is to high in the PC?

Yes.  Progress at least...

I don't know what Mic you are using.  If it is the built in computer mic you are likely to have poor audio.

USB mics work well BUT sometimes need a boost.  See this link:

Fill out a help desk request. A tech will fix it remotely. They used TeamViewer and fixed mine in an hour or less.

Use support on flex website not the community website.

https://helpdesk.flexradio.com/hc/en-...

Both resources are outstanding and each has its place neutral to have a Flex tech remote into your computer an analyze it an fix it. The community has been helpful with ideas from others that have experienced similar problems from experience. 3 rd party software issues are handled on community well.

You may need a flex tech to go into you Windows registry by remote. I would not try that myself. Totally removing a program can be a lot more than doing an uninstall.

These problems are a Microsoft screwup in my opinion.

Mike, you are more than welcome.  No patience needed. These Windows drivers issues can be frustrating.  I know because I have to develop software in Windows for a living so it can drive you crazy.
