As Mike sais, you may be hot from analog to digital. Take a look at
you Analog_Bridge.ini

[USRP] tlvAudio = AUDIO_UNITY ; Analog -> Digital (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF) tlvGain = 0.35 ; Gain factor when tlvAudio = AUDIO_USE_GAIN (0.0 to 5.0) (1.0 = AUDIO_UNITY) Change tlvAudio to AUDIO_USE_GAIN Change tlvGain to .5 Restart Analog_Bridge and retest. Adjust tlvGain to taste. Steve N4IRS

Hi Justin,
What kind of audio fob are you using? I am also having similar issues. However, I suspect there's something wrong with the audio fob I am using. This is because the audio of my IAX connection via DVSwitch mobile has excellent C4FM/DMR audio output. Geoffrey VE6GCD

I guess there is lots more to know. In your tests, what is the input to your ASL node, through USB radio interface, Local mic in computer, a asl linked station etc... In the rough, it sounds like your ASL audio is hot. Just because
it sounds good on asl output does not mean it is correct on the
input side. So before you adjust anything, verify that part or you will be
chasing your tail later.

Greetings Everyone!
I have a DVSwitch instance spun up and running and am having some audio issues. DMR > Analog: Sounds Great Analog > Allstar Node: Sounds Great Analog > Allstar to >> DMR sounds really bad. The people could hear me but had a really hard time understanding what I was saying. Are there some settings changes I can make to help with this? Thank you in advance! Justin
