[arm-allstar] Distorted Audio ??

[Doug Crompton]

Ian,

  Not exactly sure what you are doing but the current 1.1 version of the BBB can at times have distorted audio on boot. There is a 30 second delay in /etc/rc.local that in most all cases eliminates the problem but there may be some cases where the delay needs to be lengthened to maybe 45 seconds or worst case 60.  Also when you have the problem do a restart of asterisk at the linux prompt - astres.sh  - that will usually always fix the problem but it does disconnect the node(s) you are connected to so you will have to reconnect. This is a boot issue and once it is working you should not have the problem again in operation.

If this is in fact your problem then it should be greatly improved if not eliminated in the next version.

It may also be some kind of strange codec issue but I think that if you are using the BBB connected to other systems that are only PC's then you are probably only using g726. 
Lets us know if the timing or reset solves the problem.

> 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,

> Two nodes linked to each other and one linked to external node,

> BBB linked to external node, everything OK.

> Two nodes linked to each other and one to BBB and BBB linked to external

> 
> 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
