Wireshark does not decode AVTP control frames.
The MSB of the first byte after Ether type(0x22F0), is the CD bit which
indicates Control packet or data packet.
In the attached pcap the CD bit is 1 hence it needs to be decode as AVTP
control packet, but the packet is not decoded as control packet.
If the CD bit is 0 wireshark decodes the packet correctly as AVTP
streaming/data packet.
Attaching a pcap of AVTP control packet.
