[arm-allstar] USB radio - no repeat audio

[David McGough]

Hi Lu,

No flames---chan_usbradio does work (with some "audio glitches") on
RPi3 or RPi4 hardware.  I'm not sure what's happening with your setup?  

...I just tested on an RPi3A radio-less node and chan_usbradio works okay
in duplex=2 for me, using these settings:

;usbradio.conf
[usb1]
hdwtype=0	
rxboost=1
txboost=1
rxctcssrelax=1
txctcssdefault=100.0
rxctcssfreqs=100.0
txctcssfreqs=100.0
;rxctcssoverride=0
carrierfrom=usbinvert
ctcssfrom=no
rxdemod=flat
txprelim=yes
txlimonly=no
txtoctype=notone
txmixa=composite
txmixb=0
invertptt=0
duplex=1
rxondelay=0
rxnoisefiltype=0
eeprom=0


;rpt.conf
[1234]
rxchannel=Radio/usb1
duplex=2
