DSD Sound Output issue - Ubuntu 16.04

[stillline1979]

I have a uniden bearcta scanner with a discriminator output mod. It wokrs perfectly decoding audio with DSDplus in windows.

However when I try to use it with DSplus in Linux i get the error

Syncing voice output stream
An error occured while using the portaudio output stream
Error number: -9983
Error message: Stream is stopped


Below is the the output of the command dsd -a. Any help with this would be greatly appreciated. I really need this to work in ubunut as my windows machine is busy doing other things that actually pay the bills.

There is no software called DSplus that I'm aware of.

If you're able to use DSDPlus under Windows, any reason you're not using it on Linux? I suspect it'll run ok under Wine. Seems like it'd be worth a shot.

dsd+ does run under wine, but audio is open (no squelch). If there is a setting to get around that, i would love to know.

I am using it in Ubuntui 16.04 LTS. I posted the command line output in my originals post.

Any idead why it would have issues outputting sound in Linux. The specific error is


Syncing voice output stream
An error occured while using the portaudio output stream
Error number: -9983
Error message: Stream is stopped

@SDRplayer

I have no issues using DSDPlus in linux when I use an SDR as the input. You may need ti update to the latest version of MBElib. I remember having to go through multiple tutorials to install DSD on ubuntu. Some of them just didnt wokr on my machine.

The issue I am having now is that DSD plus doesnt seem to like to output audio when I am using a line input from my modified bearcat.

There seems to be some confusion about DSD versions. DSD is open source software that can be compiled to run natively on Linux. DSD+ is not open source software, and it is designed to run on MS Windows. The way I run DSD on Linux with a discriminator tapped scanner is with the port audio digital sound processor wrapper. The command line is something similar to:
padsp dsd -ipa:8 -s
Try wrapping it with padsp and use the default input (like your device #8 in your example) with whatever other arguments you need for the best sound. You may need to run "padsp dsd -a" to see the default input, as it could change because of the padsp wrap.

@ki4hyf

Thank you for your reply. This command is working perfectly now. Can you explain what "-s" does? I also like the ascii art output in the command line.

Need some more command line advice

@ki4hyf

So the command you gave me for DSD a few weeks ago is still working perfectly decoding p25 on my old Dell OptiPlex. I've been using it to listen to the D-Star roundtable on the PAPA system while I study for my technician's ticket.

My next project is trying to get rtl_fm + dsd working on a raspberry pi.

I've gotten pretty far and I'm actually seeing some good decode on on the pi but I have the same problem again where it says " an error occured while using the portaudio output stream error number: -9983"

The command I am using on the pi is below any help you could provide would be greatly appreciated.

rtl_fm -f 506.73750M -g 45 -s 16k | sox -t raw -r 16k -b 16 -c 1 -e signed-integer - -r 48k -t raw - | dsd -i - -o pa:2
