[BUG] Choppy/garbled/audio dropout on Raspberry Pi 5 using SoapySDR about rtlsdr-airband HOT 6 OPEN

from rtlsdr-airband.

I have found it easiest to narrow down where the issue is (network or machine) by adding a "file" output to your outputs and seeing if the audio experience is the same or different. I would use a file output on both devices.

You will need to create a directory for these files to go into and then note the file path. Then you can do something like the below--

outputs: (
{
type = "icecast";
server = "audio-in.liveatc.net";
port = 8010;
mountpoint = "essp2_twr_app_ctrl";
send_scan_freq_tags = true;
name = "ESSP Twr/Radar/Control";
description = "ESSP Norrkoping, Sweden";
genre = "ATC";
username = "";
password = "";
}
{
type = "file";
directory = "/your/path";
filename_template = "TOWER";
}

Syntax and explanations can be found here-

If you decide to keep the file outputs after you are done troubleshooting, you can set up a quick bash script to clean the folder every X minutes or days to prevent your storage from filling up. Some brainstorming on this here

I must say that I am pretty confident that it is network related somehow. I have listend to a lot of the recorded files and there is absolutely no choppy or garbled audio in the files on disk.

The problem came instantly after changing from a normal PC to RPi 5. Its the same internet connection 20/10mbps.

Another observation that also was reported by a listener was that VLC has "problems" with the feed, the "seconds" that ticks in VLC often skip from x:2 directly to x:5 for instance. Maybe not related, but an observation. Also VLC seems to have some kind of issue buffering the feed.

I agree with you it is likely network related. Are you using a WiFi or wired Ethernet connection to the Pi?

I might have rushed to a conclusion earlier. I have listened to even more recorded files and the choppy audio is present there as well. Its not so frequent anymore as it was 5 to 14 days ago. Maybe this rules out network after all.
