Blocking conference audio output

An electronic device, comprising:

• a network communication interface, wherein the network communication interface is to connect the electronic device to a conference server via a first communication protocol;
• a central control device communication interface, wherein the central control device communication interface is to connect the electronic device to a local central control device via a second communication protocol;
• a speaker coupled to the electronic device;
• and
• a processor to:
• receive, at the central control device communication interface, a first audio signal from the local central control device, wherein the first audio signal corresponds to audio from a nearby electronic device,
• receive, at the network communication interface, a second audio signal from the conference server via second communication protocol at a time after the first audio signal is received at the central control device communication interface, wherein the second audio signal corresponds to audio from the nearby electronic device,
• determine that the first audio signal corresponds to the second audio signal, and
• block output of the first audio signal via the speaker at the electronic device.

A non-transitory computer-readable medium including instructions that when executed by a processor cause the processor to:

• connect an electronic device to a conference via a conference server;
• connect the electronic device to a local central control device via a wireless connection;
• receive a first audio signal from the local central control device;
• receive a second audio signal from the conference server via a network at a time after the first audio signal is received via the local central control device;
• determine that the first audio signal and a portion of the second audio signal are distinct from each other;
• and
• output the portion of the second audio signal that is distinct from the first audio signal from a speaker coupled to the electronic device.
