Such an arrangement can save both field engineers and manufacturers a significant amount of time. Advantageously, in certain embodiments, such an audio adjustment system can be provided without knowledge of the electronic device's firmware. Instead, the audio adjustment system can communicate with the electronic device through an existing audio interface in the electronic device to enable a user to control audio enhancement parameters in the electronic device. For instance, the audio adjustment system can control the electronic device via an audio input jack on the electronic device. ## Claims ### Claim 1 A method of adjusting settings of a device, the method comprising: by a first device comprising one or more hardware processors, receiving an audio setting for configuring a parameter of an audio processing system of a second device; encoding an adjusted value associated with the parameter in an audio signal; and communicating the audio signal to the second device from an audio output port of the first device to an audio input port of the second device, said communicating causing the second device to set the parameter of the audio processing system to the adjusted value, said encoding further comprising: including a trigger signal in the audio signal to indicate to the second device that the audio signal includes the adjusted value for adjusting the parameter of the audio processing system, the trigger signal comprising a predefined bit pattern configured to cause the second device to: recognize that the audio signal comprises the adjusted value, decode the audio signal, and extract the adjusted value of the selected parameter. ### Claim 2 (depends on 1) The method of claim 1, wherein the parameter comprises one of the following: control data, a filter coefficient, a parametric equalization coefficient, or a decoder setting of the second device. ### Claim 3 (depends on 1) The method of claim 1, further comprising communicating, via the audio output port of the first device to the audio input port of the second device, a firmware update of the audio processing system. ### Claim 4 (depends on 1) The method of claim 1, further comprising: receiving, on an audio input port of the first device, a current audio enhancement setting from the second device, the current audio enhancement setting comprising a current value of the parameter of the audio processing system of the second device; and outputting, on a user interface of the first device, the current audio enhancement setting associated with the audio processing system of the second device. ### Claim 5 (depends on 1) The method of claim 1, further comprising: receiving, with the first device, an audio signal from the second device; decoding the audio signal to identify one or more commands in the audio signal; and causing the first device to execute the one or more commands. ### Claim 6 A method of adjusting settings of a device, the method comprising: receiving, with a first device, an audio signal from a second device, wherein the audio signal encodes parameters for adjusting one or more settings of the first device; analyzing the audio signal to determine whether the audio signal is associated with one or more commands, the analyzing comprising determining whether the audio signal includes a trigger signal to indicate to the first device that the audio signal includes adjusted values of the parameters;

and causing the one or more hardware processors of the first device to execute the one or more commands using the at least some data packets. ### Claim 7 (depends on 6) The method of claim 6, wherein the parameters comprises video parameters associated with the first device. ### Claim 8 (depends on 6) The method of claim 6, wherein the one or more commands cause the one or more hardware processors of the first device to adjust an enhancement parameter associated with an audio processing system of the first device. ### Claim 9 (depends on 8) The method of claim 8, further comprising, receiving by the audio processing system a second command from a television application configured to control operation of a television, and the second command configured to implement the one or more commands in the audio processing system. ### Claim 10 (depends on 6) The method of claim 6, wherein the one or more commands are configured to obtain information about the audio processing system for presentation to a second device, and the method further comprises causing the one or more hardware processors of the first device to: encode the information about the audio processing system, and communicate, via an audio output port of the first device the encoded information to the second device. ### Claim 11 A system of adjusting settings of a device, the system comprising: memory that stores instructions associated with an audio-visual adjustment system for adjusting settings of a first device, wherein the audio-visual adjustment system comprises at least one of an audio processing system or a video processing system; and one or more hardware processors that execute the instructions to: receive an audio communications signal from an audio input port of the device; decode the audio communications signal to obtain a first command for adjusting an audio processing system or the video processing system; execute the first command to adjust the audio processing system or the video processing system; encode a second command for communication to a second device; and communicate the second command to the second device to cause an operation related to audio-visual settings to be performed on the second device. ### Claim 12 (depends on 11) The system of claim 11, wherein the audio-visual adjustment system is implemented in a television. ### Claim 13 (depends on 12) The system of claim 12, wherein the audio-visual adjustment system comprises a television application configured to adjust the audio processing system or the video processing system based at least partly on the first command. ### Claim 14 (depends on 11) The system of claim 11, wherein the settings comprise an audio enhancement setting or a video enhancement setting. ### Claim 15 (depends on 11) The system of claim 11, wherein the second command causes the second device to set an audio-visual enhancement parameter on the second device. ### Claim 16 (depends on 11) The system of claim 11, wherein the first command comprises a plurality of synchronized packets interspersed with a plurality of data packets, and wherein a synchronization packet of the plurality of synchronization packets is configured to separate a data packet from a preceding data packet.
