OP25 OP25 Value error when running ./rx.py

[Falcon4]

Hello everyone its been a while. So sometime last year my lovely wife threw out my working RPI4 running OP25 flawlessly running liquidsoap the whole 9. I finally got another Pi, No,I didn't get a divorce Anyways, I'm getting a weird value error and I'm thinking it has to do with the NAC I'm trying to monitor being "00A"? Here's what I got:

File "/home/falcon4/op25/op25/gr-op25_repeater/apps/helper_funcs.py", line 156, in read_tsv_file
key_val = int(fields[key], 0)
ValueError: invalid literal for int() with base 0: '00a'

Any help would be appreciated. I hoping I can get this running again with not too much pain because the more roadblocks I encounter the more I think about calling my laywer

How recent is your present build of op25? Can you post your tsv file?

Sorry, for the delayed response got really busy at work. Well ,figured out my rx.py issue my NAC was incorrect in my trunk file. Now that I moved past that i'm in the dreaded no audio phase of the build. Last time I built it I remember it magically working one day after just letting in run. I went back and read a lot of my old threads after all that I should've just copied my SD card to a file somewhere just in case. I'll definitley do that this time around.

For some strange reason my Do_Audio_output is reading [0] no matter what I try. -O,-O alsa , -O Pulse. Ran a test .wav can hear that loud and clear. Here's my Stderr.2 and my Rx.Py/

Thank you again, Got another long week of work ahead of me.

The -O command line option requires a parameter, so the command line you quoted is incorrect as written. I'd suggest simply removing the -O and leaving op25 to use the default audio device as that works most of the time. The other common option would be "-O pulse" to force the use of Pulse Audio (rather than ALSA).

Also, you can lower your sample rate to save some CPU. There is no real advantage to sampling a wider bandwidth than the minimum for any given sdr device. e.g. for an RTL use "-S 1e6" or "-S 1000000"

Tried -O pulse,removed the -O parameter, no audio. Minimized the sampling rate. I played test audio using the $ aplay command and heard it so my thought process its not a pi issue. I'm still getting do_audio_output [0] in my stderr.2.

Add a "-U" to the command line

Add a "-U" to the command line

Eureka!! Thank you! I feel like an idiot how could I have missed "enable built-in UDP audio player" total face palm on my part. Hahah on to the next part of the build...liquid soap. Again thank you!

Hint: when you implement liquidsoap you'll need to remove the "-U" parameter

And add the "-w" and "-V" parameters. Just a heads-up, you may experience difficulties with Liquidsoap that will depend upon the
version of Raspbian OS used to image your Raspberry Pi. Specifically, the Desktop (GUI) versions install pulseaudio by default that can
be problematic for headless operation whereby Liquidsoap has been configured to run as a system service.

Don't let that discourage you, just come back if you run into any problems and we'll help you out.

Ok, so back at it again. I'm pretty sure I configured my meta.json,op25.liq and my icecast.xml. I tried to follow the readme rpi3-liquidsoap. In there in instructs to install liquidsoap to "sudo apt-get install liquidsoap liquidsoap-plugin-all". However, when I did that it said that "liquidsoap-plugin-all" is not available. I used "Sudo apt-get install liquidsoap" but now I'm getting an error:

Am I missing an encoder that was in the "plugin all" package?

 

[boatbod]

You don't need the fdkaac encoder so the warning can be ignored.

So it's safe to say something isn't right with my files I'll have to go over them again. Reason why I say that is because that is the last line I see and im not logging anything.

You might have to play around with these parameters in the .liq script

set("log.stdout", true)
set("log.file", false)
set("log.level", 1)

In particular the log.level likely needs to be 3 or higher to be useful.
