OP25 VirtualBox Project - Run OP25 on Windows 7

[Dark-Sky]

There are no pulse anything in /etc/group. It looks like it is set up as a per user basis and not system wide. op25.lig runs fine using pulse after logging into a desktop. I can even set up a liquidsoap .desktop file in .config/autostart and it will run with autologin enabled at the graphical login screen.

Pic showing pulse loaded as default:



Like I said above not really worried about the local audio being alsa as the arm device will be headless and will not listen to it local anyway.

@boatbod So.. I installed new version of Ubuntu 18.10 fresh. I had this working alright on 14.04 for awhile, but I ran into some compat issues with other things on that old build so i'm building a new. I keep getting hung here when its compiling. What am i doing wrong?

What happens if you run this:
sudo apt-get install swig

It could be a problem with cmake. Had this once before on arch linux. What cmake version are you running?

cmake --version

cmake --version

cmake version 3.12.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).

cmake version 3.12.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).

I recommend trying an earlier version of cmake. Ideally, whatever version is used in Ubuntu 16.04

Sorry, not in front of a computer to check mine. Can do that later.

 

[djshadowxm81]

@boatbod So just install an older version of cmake alongside and point the script to that cmake binary instead then?

 

[djshadowxm81]

kicked it down to cmake 3.10.3 and it works fine. Thanks for the tip Graham!

Version 3.11.4 works ok for me.

A while back I was working with another member running Arch linux and we ran into the exact same issue. Something changed in later cmake versions that have caused the ~/op25/cmake/Modules/GrSwig.cmake script to specify build dependencies in the wrong order. I pinpointed exactly what was going wrong with the resulting makefile but coudn't figure out a workaround to the .cmake script.

I appreciate your help now one thing tackled now I just got to figure out why I'm still having issues routing audio into Discord via pulseaudio for a low latency stream I use to get it to my phone. I tried the ice cast functionality but it's just not fast enough to get the audio that I need to my phone for it to be actionable. I have a sneaking suspicion it's something on Discord end because this is working just up until about a week ago so I don't know thanks for your help though!

 

[Dark-Sky]

Although I do not not use Discord icecast with darkice and now liqudsoap has worked out just fine here streaming out on the internet using a dynamic dns provider even receiving on my phone.

I do not know if it will help in your case but have you tested your bufferfloat on dslreports.com. I have known of people in the past having issues due to bad bufferfloat with voip. Here is my report from dslreports.com. I have one of my pi3's set up as an openwrt router so I could tune it for the best results:

 

[djshadowxm81]

I do work for a major ISP lol I know all about bufferbloat. The latency is probably as low as its gonna get. It's just an intrinsic thing with streaming services it seems. VoIP software like discord gets it down to like 1-2ms of latency where as its like 15-20ms of latency with icecast or shoutcast streaming servers. I should also add that this exists when streaming locally within the network as well.

Turns out it was a recent update with discord that broke everything

So I decided to get ambitious and install Mint 19.1 on a spare Intel NUC i5 I have lying around doing nothing important. Seemed to install properly, had to apply a patch to the Broadcom WiFi adapter and the computer itself runs. I did the boatbod op25 install routine that seemed to work, but running the program fails - it seems that op25 is not finding the RTL device and exits.

Here is my command line and results:


charley@NUC:~/op25/op25/gr-op25_repeater/apps$ ./rx.py --args 'rtl=0' -N 'LNA:32' -n -q 0 -S 370000 -f 773.83125e6 -d 25 -T trunk.tsv -V -2 -U 2> stderr.2

charley@NUC:~/op25/op25/gr-op25_repeater/apps$

Here is the stderr.2 file:

Ideas?

(this cmd line and rtlsdr works fine on my rpi3+

Did you blacklist the kernel modules?

cat /etc/modprobe.d/blacklist-rtl-sdr.conf
blacklist r820t
blacklist rtl2832
blacklist rtl2830
blacklist dvb_usb_rtl28xxu

 

[boatbod]

Blacklist is the most likely culprit. Add those configs and reboot.

cat /etc/modprobe.d/blacklist-rtl-sdr.conf
blacklist r820t
blacklist rtl2832
blacklist rtl2830
blacklist dvb_usb_rtl28xxu

I did none of that because I don't know what that does and why...

 

[Dark-Sky]

Just in case "how" was either left out or in the periods. Create a file called blacklist-rtl-sdr.conf with nano in /etc/modprobe.d/ and add the 4 lines:

sudo nano /etc/modprobe.d/blacklist-rtl-sdr.conf

blacklist r820t
blacklist rtl2832
blacklist rtl2830
blacklist dvb_usb_rtl28xxu

When through adding the lines close out nano and save the file with CTRL-X and type y and hit the enter key. Then reboot so that what ever kernel module that has your device tied up can be released..

 

[maus92]

Thanks for helping.

OK, did as instructed, (created file and rebooted) but with the same results. This is the fie I created:

charley@NUC:~$ cat /etc/modprobe.d/blacklist-rtl-sdr.conf
blacklist r820t
blacklist rtl2832
blacklist rtl2830
blacklist dvb_usb_rtl28xxu
charley@NUC:~$


(should I be changing the "xx" in "blacklist dvb_usb_rtl28xxu"?)

This is the run cmd:

charley@NUC:~/op25/op25/gr-op25_repeater/apps$ ./rx.py --args 'rtl=0' -N 'LNA:32' -n -q 0 -S 370000 -f 773.83125e6 -d 25 -T trunk.tsv -V -2 -U 2> stderr.2
