The actual amount of bandwidth used for audio is variable depending on the available network resources.  PCoIP software will automatically adjust the audio compression used.  For example, the top (high experience) two default schemes average ~1.5 MBit/s and 350 kBit/s but can be much lower if the network is constrained, or bandwidth limits have been set for the session.

To tell if there is significant audio network traffic, look at the packet counts in the VGMAC: entry in the PCoIP logs.

From the PCoIP log files, the first number after T= is the number of audio packets sent (in this case 4725) since start of session. Look at the packet count between samples, you can get an estimate. For estimation purposes, between 5 to 10 kbits per packet can be assumed (since the actual audio compression is dynamic).

Note: All are packet counts, not bit counts.
