When users are talking I’m hear the audio sound on the node with some kind of noise
With that limited info,
I can only give you 2 most popular possibilities.
You are generating a PL tone or passing a PL tone that is not filtered on the output.
You have RF on your audio lines.
I’m don’t know what it is but when I’m hearing a station and I’m belive there hear it there side when I’m talking it sounds like a pl tone is ot any fix on this that if it is this issue though if we can fix a pl tone and if its not that we can look more in to it how’s that sound do you need look at the config file? If u do please let me know what file you need please
I’m have done a audio file but it’s not in mp3 and will not let me post it
Well it would not hurt to see your
simpleusb.conf or your usbradio.conf depending on which channel driver you are using.
You might try to send the mp3 as a personal message to me and if that works, I will post it for others to hear if it is not obvious to me.

; 0 = no warning message if no EEPROM found.
rxboost=1
; Rx Audio Boost
; 0 = 20db attenuator inserted
; 1 = 20db attenuator removed

; Options - no,usb,usbinvert
; no - no carrier detection at all
; usb - via USB radio adapter COR connection
; usbinvert - same as above but inverted polarity.
ctcssfrom=usb
; CTCSS Decoder Source
; Options = no,usb,dsp
; no - CTCSS decoding, system will be carrier squelch
; usb - CTCSS decoding using input from USB adapter
; usbinvert - same as above but inverted polarity.

; default value is 0
; rx audio delay for squelch tail elimination.
; Squelch tail delay in 20ms frames. Values range
; from 0 (no delay) to 24 (480ms delay)
