Issues with audio on NXDN, and audio cutting out in live listening

[Zach Rutledge]

Using the latest nightly, I've got successful decoding of my local P25 network, and also a local NXDN 4800 network.  But the problem is the audio from the NXDN network is way WAY louder than anything else, and it's so distorted that it's almost impossible to hear what's being said on the majority of transmissions.

Is there some way I can adjust down the audio of just that one particular channel/network?

I don't see much in the way of audio options in the app other than the checkbox for "normalize audio before encoding" but that doesn't help anything as far as I can tell.

Flipping back to DSD+, the audio is still pretty loud but it's definitely clean and clear (as much as NXDN 4800 can be, which isn't much).

Not sure if it's related, but I do seem to have issues with live audio cutting out in the nightly, too.  Audio is still recorded locally and also sent to streaming, but live plackback seems to go silent occasionally.  I've noticed an error saying:

2026-08-19 03:02:07.624 ERROR i.g.d.a.p.AudioOutput - Couldn't obtain MASTER GAIN control for stereo line [Speakers (Realtek(R) Audio)] [Log Suppress 2/2]  [427MB/758MB 56%]

It comes back if I restart the app or go into settings and change sound cards back and forth.  I've also noticed that there's no longer any volume control for the left/right channels as in 0.6.1, is that a bug related to this issue?

I'm working on the JMBE library now to add in an AGC feature that should address the issue for NXDN and the other protocols.

The error entry example that you posted is related to your audio playback hardware and simply means that configuration doesn't expose a master gain control that can be controlled by the software ... unrelated to the other playback issues you're trying to understand.
