I'm using hcidump to analyse audio traffic. Samples are 8 bit long and 
voice setting is properly set. The link works just fine. The dump log 
shows that 24 byte long data packets are sent and received. Question is 
what does the hcidump actually measure. Does it really report the 
contents of SCO packets (HV1, HV2 and HV3) that are sent with BT radio 
or does it just sniff send and receive buffers? The 24 byte seems 
strange since the payload of packets is supposed to be 10, 20 or 30 
bytes. Is there something that I have not noticed?

it is the payload of the SCO packets that are send over the HCI.
