In the Media settings, Unicast Video Redirect and Multicast Direct Enable should be enabled.

EDCA Parameters

Set the EDCA profile for Voice Optimized and disable Low Latency MAC for either 5 or 2.4 GHz depending on which
frequency band is to be utilized.
Low Latency MAC (LLM) reduces the number of retransmissions to 2-3 per packet depending on the access point platform, so
it can cause issues if multiple data rates are enabled.
LLM is not supported on the Cisco 802.11n Access Points.
