Your best bet is to purchase DSDPlus Fast Lane and use the FMPA tuner along with DSDPlus FL.

I have used DSDPlus Fast Lane with an SDR# and VBcable and seperratly also by using the FMPA control for AirSpy (no SDR# or VBcable needed) in DSDPlus Fast Lane. Never had any problem on Win 7, Win 8, and Win 10.

I did not have to do anything to get audio out--it just happened (VBCable not involved with the audio coming out--it just went to the speakers all by itself). I assume yo are not using Fastlane?
Ok guys thanks for the help. The big problem was the DSD+ sparse documentation did not mention that Windows 10 must be set to allow apps to access the microphone as apparently it is not by default. The second issue is is apparently DSD+ only outputs audio on a valid decode and the audio scope that DSD+ provides only shows a very low, almost imperceptible signal amplitude on decode, not very useful. I am not using fastlane as it is not on the DSD+ website. Don't know where they hide it. It appears you have to send them money before a link to download is provided, if that is the case, they should post that on the site. All they want to do is take the money without explaining what happens next. A very poorly executed website. In spite of this, it is working now.
Buy DSD plus fastlane, nothing else is needed works great and no other programs or patches are needed.
It's been a long time since I used that free version but I really do not remember having to use or do anything with the microphone.
If you were on their site, it's all right there on the top of the page.
Did you click "Read More"?
And the text from the above image is also in the DSDPlus.txt file in your dsdplus folder.
.
There is very little online on what DSD Fastlane does. There is no documentation, instructions or Wiki or what it does that is better than DSD Plus. I realize that DSD software is the effort of one individual but still, the documentation can be better and missing a important point such as Windows 10 must be set to allow apps to access the microphone in order to for DSD+ plus to operate is a major omission. I will just leave it at that.
I don't understand the microphone part. With DSD+Fastlane no cables needed. It has a readme file to set everything up. Run Zadid to install your tuner. launch DSD FMP24cc, then 1r radio in the folder.
If you want to learn what it does, spend 10 bucks and read the posts.
With plain DSD+ you do need the Virtual Cable and allow Windows 10 apps to access to the microphone.
What posts? I have spent hours searching here and on the internet finding not much info on DSD Fastlane. I am not going to spend any money on something with such little documentation. Why should I pay to obtain a readme file only to find out the software may not even suit my purpose. I need the features of SDR# and have yet been able to determine what specifically DSD+ offers. Why does DSD Fastlane not have an online manual?
No, you just need vb or vac cable, and nothing with the microphone at all.
Most likely, you did not read the dsdplus.txt file that explains how to configure input audio options. So if you did not define vb cable as in input, it was defaulting to the mic as the input which is why Windows was asking for access. Microphone has nothing at all to do with DSDPlus or virtual cables. .
The pic below is what DSDPlus displays on start up. You need to see what number is listed for your vb cable on the input side and edit the bat file to reflect that. So then when you restart DSDPlus, it sets vb cable as the input. The last 2 lines in the pic display what the program is using as input and output.
I would bet if you fired yours up, that line would say its using the microphone.
Maybe state what your looking to do so others who use FastLane could give you helpful advice?

Strange thing that even after spending hours here on RR you didn’t find any information about DSDPlus Fastlane. Top right on this page you’ll find a magnifying glass. Click on it and typ DSD+, DSDplus or DSDplus Fastlane and click on search. You’ll get several hours of reading to do on information about DSD+ and DSD+ Fastlane 😉
This is straight from RR forums:
"Assuming Windows 10, make sure that you've given permission for apps to use the "Microphone". Yes, this affects virtual audio cables on the input side as well.
Settings > Privacy > Microphone > Allow apps to access your microphone > ON"
I have found this to be absolutely true using DSD+. Maybe Fastlane does not require this, but that is not what I was using.
This is straight from the RR forums:
"Unfortunately, the is no one stop guide to setting up DSD+ FL. The notes file is a start, but not everything you will need to do is listed in the notes. For full trunking, you will need to edit the networks, sites, site loader, frequencies, and groups files. There are examples within each file. To start, you will need to run 1R and FMPx, x= fmp24 for RTL SDR dongles or similar devices, FMPA for Airspy devices, and FMPP for SDR Play devices."
That is my point. I can find lots of tid-bits but no comprehensive guide on setup or what Fastlane does. Does it work on more than one frequency? Does it have a spectral display? How wide if it does. Or is it channelized like a scanner? Will decode P25 Phase two? Will it run an IC-R8600? I could go on...I'm sure I could spend hours and finally find this stuff out, but is there no setup guide, wiki, or online manuals. I standby my assertion that online documentation is poor.
FMP24 (dongle), FPMA (Airspy) and FMPP (SDRPlay) all have a spectral display. It displays just what is needed and nothing more. It is by no mean fancy, like SDRsharp or SDRuno. But it's lightweight on resources and works perfectly with DSDPlus FL.
DSDPlus doesn't monitor more than one frequency at a time. If you wanted to do that you would need more than one dongle, need to run multiple instances of FMP*+DSDPlus FL, and best to run each from its own directory. You can change the freq you want to monitor using FMP* . So it will monitor whatever freq you want, but only one at a time.
You can have a scanlist, but that should only be used if you are scanning conventional (non-trunked) freqs. No channelization for trunked systems. Yes it decodes P25 PHase II (including TDMA control channels). No, it won't run an IC-R8600 (and you shouldn't expect it to). You could fee unfiltered audio from your R8600 into your Line In jack on your computer and then feed the line-in into DSDPlus.
Online documentation is poor to nonexistent. People are expected to do their homework, and read. I have no problem with the lack of online documentation. You should thoroughly read (multiple times) every *.TXT file in the DSDPlus folder, as well as the examples at the top of the DSDPlus.Networks / .Sites / .Freqs / .Groups / .Radios files.
And you should not expect that ancient DSDPlus free version to do everything the new version does. It doesn't. It never will. Update or not, that's your choice. But I can guarantee you that you don't want to email complaints to the author.
That's all I'm going to add. I personally won't respond to any other questions of yours unless/until you are running DSDPlus FastLane. I can only offer help with up to date software. What you are doing is equivalent to asking people to help you learn how to use Windows 3.1 when you should be running Windows 10/11 lol.

Just stay far away from DSDPlus. DSDPlus is not build by a company, it’s build by a hobbyist. He build a program, not a fancy hand-out.
You can copy, paste and complain as much as you like to make your point. Does this help you to understand DSDPlus or inspire members to help you?
When I first got DSD+FL installed, it is a bit of learning curve. Moot on my Dell but soon to install on an HP with a different sound setup.
For me, once I got the setting right, it just worked. I ended up with a dozen .BAT files for the different frequencies/systems
I could load one for the local P25 public safety and worked. One set up for NXDN and worked.
It is not as intensive as programming a radio for NAS, but if I can do it, anyone can.
Now, how to get sound working on this HP tower.
Cheers.
