I installed Windows 10 (April 18 update) on external SSD drive that can be selected on the iMac's startup. Run the Boot Camp Windows Support Software and everything is fine, Apple mouse & keyboard, except audio is missing. Windows 10 Device Manager app does not show any problems with the drivers such as yellow triangles or red crosses. In fact, when a video is played the green volumen bars in the audio device driver properties move but there is no sound at all.
You can also visit your PC manufacturer's website to download the Realtek High Definition Audio driver.

Avance Logic, Inc. was a hardware manufacturer founded in 1991 in Fremont, California, and was most recently headquartered in San Jose, California. Avance Logic focused particularly on the development of low-cost, highly integrated electronic components for OEM manufacturers and was active in the areas of 2D graphics and audio. A 3D accelerator was developed in the mid-1990s, but it was not widely used. Avance Logic was acquired by Realtek as early as 1995 and was an independent subsidiary until the end of 2002, when the company was integrated into Realtek. Realtek's Audio Solutions are based on Avance Logic technology, which can also be recognized by the prefixes "ALG" (Avance Logic Graphics) and "ALS" (Avance Logic Sound).[4]
Advanced Linux Sound Architecture (ALSA) provides audio functionalityto the Linux operating system. The NVIDIA ALSA System-on-Chip (ASoC)drivers enable ALSA to work seamlessly with different NVIDIA SoCs.Platform-independent and generic components are maintained by the upstreamLinux community.
The ALSA framework is a part of the Linux kernel that is supported andmaintained by the Linux community. This makes it feasible toadapt the framework to the Jetson device by designing a driver thatutilizes NVIDIA audio routing support. ALSA includes a collection ofsound card drivers, including actual codec drivers, and can supportadding new codec drivers.
ALSA includes libraries and utilities that enable more refined audiocontrol in Linux user space. These libraries control audio applicationswithout having to interact with kernel space drivers directly. Theselibraries include:
The ASoC driver provides NVIDIA Audio Hub (AHUB) hardware accelerationto the platform and codec drivers. AHUB Direct Memory Access Interface(ADMAIF) is implemented as a platform driver with PCM interfaces forplayback and capture. The rest of the AHUB modules, such as the crossbar (XBAR), multiplexer (AMX), demultiplexer (ADX), andinter-IC sound (I2S), are implemented as codec drivers. Each of thedrivers is connected to XBAR through a digital audio interface (DAI), inside a machine driver, forming an audio hub.
The machine driver probe instantiates the sound card device andregisters all of the PCM interfaces as exposed by ADMAIF. After booting,but before using these interfaces for audio playback or capture, you mustset up the audio paths inside XBAR. By default, XBAR has no routingconnections at boot, and no complete DAPM paths to power on thecorresponding widgets. The XBAR driver introduces MUX widgets for all ofthe audio components and enables custom routing through kcontrols fromuser space using the ALSA amixer utility. If the audio path is notcomplete, the DAPM path is not closed, the hardware settings are notapplied, and audio output cannot be heard.
Users must connect some or all of these ports to form a full audiorouting path. For examples of full audio paths, see the examples inUsage and Examples. Note that there are otherelements in a full audio path setup, which are discussed in subsequentsections; the playback/capture ports set up by the platform driverare only a subset.
If the sound card is available after boot, that indicates that the machinedriver was successful in binding all codec drivers and the platform driver.The remaining step before obtaining the audio output on the physical codecsinvolves the use of MUX widgets to establish the DAPM path in order to routedata from a specific input module to a specific output module. Input andoutput modules are dependent on the applicable use case. This providesflexibility for complex use cases.
Mixer controls are registered for each instance of AMX by the respectivecodec driver, and are used to configure the path, characteristics, andprocessing method of audio data. The table below lists instance-specificmixer controls.
Mixer controls are registered for each instance of ADX by the respectivecodec driver, and are used to configure the path, characteristics, andprocessing method audio data. The table below lists theinstance-specific mixer controls for each instance of the ADX module.
Mixer controls are registered for each instance of I2S by the respectivecodec driver, and are used to configure the path, characteristics, andprocessing method of audio data. The table below lists instance-specificmixer controls.
The Mixer mixes audio streams from any of the 10 input ports thatreceive data from XBAR to any of the 5 output ports that transmit dataonto XBAR. The DAPM widgets and routes for Mixer are shown in thefigure below. The Mixer driver also exposes RX Gain and Mixer Enable asadditional kcontrols to set the volume of each input stream and toglobally enable or disable the Mixer respectively.
Mixer controls are registered for each instance of Mixer by thecorresponding codec driver. They are used to the configure path,characteristics, and processing method of audio data. The table belowlists instance-specific mixer controls.
Mixer controls are registered for each instance of SFC by thecorresponding codec driver. They are used to configure the path,characteristics, and processing method of audio data. The table belowlists instance-specific mixer controls.
Mixer controls are registered for each instance of DMIC by thecorresponding codec driver. They are used to configure the path,characteristics, and processing method of audio data. The table belowlists instance specific mixer controls.
Mixer controls are registered for each instance of MVC by thecorresponding codec driver. They are used to configure the path,characteristics, and processing method of audio data. The table belowlists instance-specific mixer controls.
Mixer controls are registered for each instance of DSPK by thecorresponding codec driver. They are used to the configure path,characteristics, and processing method of audio data. The table belowlists instance-specific mixer controls.
The structure snd_soc_dai_link, in ASoC core, defines a linkthat connects two DAIs from different modules. Such a link is called aDAI link. A given machine driver can have one or more of DAI links,which are connected at runtime to form an audio path.
You must update these items because the machine driver parses the device treein order to instantiate the sound card. Update the device tree properties ofthe sound node for the Jetson device when you customize to support athird-party audio codec.
nvidia-audio-card,widgets: Defines machine source or sink widget endpoints.ASoC core provides predefined identifiers which can be used to define therequired widgets. The machine driver need not maintain these widgets explicitly,and can make use of this property to declare the required number of widgets.
The following debugfs node listing, obtained from/sys/kernel/debug/clk/clk_summary, shows the clock tree of the ASoCdriver for Jetson AGX Xavier in the idle state, when no audioplayback or capture operations are in progress. The clock trees for the otherJetson devices are similar.
Jetson devices support one or more High Definition Audio (HDA)interfaces through on-board HDMI, DP, and USB-C ports. These interfacescan be used to perform high-quality audio rendering on devices like TVs andA/V receivers. These HDA interfaces are available on various Jetsondevices:
You may experience issues when playing high resolution audio formats(using multichannel output or a high sampling rate), even with an audioformat that your monitor supports. This is because the availableaudio bandwidth depends on the HDMI configuration, increasing withhigher display resolutions.
If you encounter issues when playing a high resolution audio format,NVIDIA recommends setting your display resolution at least to the levelthat corresponds to your audio format in the following table. This tableis taken from theHDMI 1.3a specification document.
The ASoC machine driver parses the sound device node to register a sound card. The following sections describe various elements of the sound node whichmust be configured for the audio card to work properly. These include I2S and the external codec DAI link configuration, the description of audio DAPM widgets and routes,clock configurations, and I2S mode settings.
Unfortunately, even if you have the best computer or the best Windows laptops, there are still a million and one different things that can break your audio drivers and cause you a huge headache in the process. If this happens to you, the first step is to head straight to your device manager and see if you can get a fresh driver through Windows Update.
