[cma-l] Streaming audio problem

[Tony Bailey]

Is it being throttled or are there are other users on the connection? 
Assuming that the bit rate is high (128k?) try running at 24k mono as 
that would be below most data transfer limits these days. If that works 
gradually increase the bit rate.

Regards,  Tony Bailey
