[arm-allstar] Distorted Audio ??

[gm4upx at gb7jd.co.uk]

Hello,

I have an anomaly here with my audio and hopefully someone can shed some 
light on it for me although it may be more Allstar related than BBB 
specific.
Here's my setup, previous and now.

Previous:
Three nodes running on one PC with URIx, all working OK.

Present:
Two nodes running on one PC and one node running on BBB with URix, 
everything ok.

Two nodes linked to each other and one linked to external node, 
everything OK.
BBB linked to external node, everything OK.

Two nodes linked to each other and one to BBB and BBB linked to external 
node, everything OK.

Two nodes linked to each other and one to BBB and one or other node 
linked to external node, RF audio via BBB distorted and crackly on some 
external nodes only

I have port 4568 to BBB and port 4569 to other two nodes; I have the PC 
ip address in rpt.conf for the BBB and BBB ip address in PC rpt.conf. ( 
no :4568 or :4569, didn't seem to make any difference )

The audio arriving at my nodes is OK ( when listening via webtransceiver 
) so it appears that the audio passed from my PC to my BBB is at fault, 
but not all the time !!! Grrrrrrrr!!

Regards,

Ian..
