DSD+ voice receiving but no audio

Post by reyntjensm » Sat Jan 11, 2020 4:19 pm

Dear all,

I'm a newbie to SDR, i'm able to receive voice without any issues.
Altough i wanted to try some digital stuff. So i installed the DSD+ plugin and i'm receiving group calls/voice.
I guess this voice should be audible?
I had to change my audio settings in windows to get access to the virtual cable( see attached image). In SDR# on what should i set the audio device for the DSD interface plugin? If i send this to my speakers i only hear the incoming digital data. If is set the audio device to the Virtual cable nothing changes. What should i do to be able to hear the decoded audio? Or is this no DSD+ audio? Thanks to you all for the support!

I am new at this, too. I found this page explaining how to set everything up. I am trying to work my way through it. I have only one dongle at the moment and some parts of this have not worked for me yet. I may uninstall Unitracker and start all over.

Anyhow, it may be worth a look

I was having the same issue too but, I think I figured it out

In SDR# under the "DSD Interface" tab, un-check "Enable aux audio output".

Then, make sure that the "Audio device option", directly under the "Enable aux audio output" check option, is set to your speaker/headphones.

Also, this clip here --> https://www.youtube.com/watch?v=p4lrm_TxYuc&t=298s gives a good walk through for making sure that your audio is going to DSD+

You'll only hear audio when DSD+ has decoded the transmission.

Finally I download AIRSPY (Community Package with Plugins) https://airspy.com/?ddownload=5544 and they have the tab name (DSD INTERFACE*) and you can select your windows direct sound. But one thing in SDS+ he cut the sound on P25 scramble channel. DSD+ mute option was 'ON' by default. Possible to shutdown at OFF and listen scramble sound?
