Abstract: An orchestrator associated with a collaboration application client executed by a near end device dynamically adapts volume level and/or other audio quality parameters to deliver a consistent voice experience to a collaboration participant. The orchestrator is informed by multiple machine learning engines collecting and analyzing inputs from one or more existing sensor-based functions embedded in the near end device. The orchestrator determine an audio configuration of the device and audio preferences of the user. Identities of far end participants are determined and their profiles are mapped against the user volume preferences. The orchestrator functions as an informing agent to the audio signal processing engine of the device, managing speaker output volume and microphone gain settings, based upon the machine learning engines and the sensor-based functions. The sensor based functions may detect proximity, head pose, gaze point, eye position, facial identities, mood, and so forth.

Abstract: An information handling system plays audio provided from a portable audio device at an information handling system audio subsystem in operating and powered down states of the information handling system. In the operating state, digital audio information is communicated from the portable audio device through a serial link for rendering at the information handling system into an analog audio signal presented by the audio subsystem. In the powered down state, digital audio information is rendered at the portable audio device and communicated as an analog audio signal through the serial link to the information handling system. A system module at the information handling system selectively switches the serial link to interface with the audio subsystem and play the analog signal as audible sounds. The system module supplies power to the audio subsystem to support playing the analog signal with the information handling system in the powered down state.

Abstract: A smartphone selectively supports a telephone call in a handset mode or a speakerphone mode by enabling or disabling microphones and speakers integrated in the smartphone. In the speakerphone mode, plural microphones determine a direction of a participant of a speakerphone telephone call so that audio of the speakerphone telephone call from plural speakers of the smartphone is beam steered towards the participant.

Abstract: An analog connector disposed at an information handling system housing accepts both analog audio information and digital audio information at plural connection surfaces by accepting either an analog or digital jack. An audio subsystem of the information handling system manages audio information at the connector by selectively configuring to handle analog or digital signals based upon the type of jack insert into the connector. Selection of analog or digital management is performed manually through a user interface or automatically by detection of the type of jack inserted in the connector. In one embodiment, a four pole analog connector accepts a four pole digital jack that communicates serial data through a pole connection surface instead of analog signals.

Abstract: Information handling system audio jack tasks are selectively set by an end user through an audio driver jack retasker that associates each of plural audio jacks with one of plural tasks in a jack task table. For example, a WINDOWS operating system having a UAA class driver supports jack retasking by providing end user access to UAA jack task tables stored in system BIOS. Audio jacks are selectively retasked between audio tasks, such as microphone signal in or headphone speaker out, and other tasks, such as line in or line out functions.

Abstract: The configuration of active jacks at an information handling system is sensed by temporarily diverting an analog-to-digital converter from a primary function upon detection of a change of the configuration of active jacks. A jack sense circuit outputs a unique voltage for each configuration of jacks, such as with a resistor tree. A change in the jack sense voltage generates an interrupt by a jack sense interrupt, which communicates the interrupt to a multiplexer. The multiplexer temporarily interfaces the jack sense output voltage with the analog-to-digital converter to have the jack sense output voltage converted to digital information that identifies the jack configuration. After detection of the jack configuration, the multiplexer returns the analog-to-digital converter to its primary function, such as converting analog microphone signals to digital information.
