5. A method, comprising:
determining that a first device is associated with a first device type indicating the first device is configured to output audio in a first audio frequency range;
determining that a second device is associated with a second device type indicating the second device is configured to output the audio in a second audio frequency range that is lower than the first audio frequency range;
designating, based at least in part on the first device being configured to output the audio in the first audio frequency range and the second device being configured to output the audio in the second audio frequency range, the first device to receive first content data utilizing a unicast transmission, wherein the unicast transmission includes a first identifier of the first device that is designated to utilize the first content data for content output, wherein a first wireless component of the second device has been configured to utilize data packets sent as the unicast transmission and directed to the first device for the content output;
sending the unicast transmission of first data packets representing the first content data to the first device;
receiving, from the first device, first data indicating packets lost at the first device; and
sending, to the first device and utilizing the unicast transmission, second data packets representing the packets lost at the first device, wherein sending the second data packets causes the first device to receive the second data packets as the unicast transmission and causes the second device to utilize the second data packets for the content output.
