It is designed to support the USB Audio 2. The driver is a WaveRT audio port class miniport. For more information about the USB Audio 2. The driver is named: usbaudio2. This name will be overwritten with a USB Product string, if it is available. The driver is automatically enabled when a compatible device is attached to the system. However, if a third-party driver exists on the system or Windows Update, that driver will be installed and override the class driver.

The driver supports the formats listed below. An alternate setting which specifies another format defined in FMT-2, or an unknown format, will be ignored. The driver supports one single clock source only.

For the asynchronous OUT case the driver supports explicit feedback only. A feedback endpoint must be implemented in the respective alternate setting of the AS interface. The driver does not support implicit feedback. For the Adaptive IN case the driver does not support a feedforward endpoint.

If such an endpoint is present in the alternate setting, it will be ignored. The size of isochronous packets created by the device must be within the limits specified in FMT A function with an audio control interface but no streaming interface is not supported. The driver supports all descriptor types defined in ADC-2, section 4. The following subsections provide comments on some specific descriptor types. An AS interface descriptor must start with alternate setting zero with no endpoint no bandwidth consumption and further alternate settings must be specified in ascending order in compatible USB Audio 2.

Each non-zero alternate setting must specify an isochronous data endpoint, and optionally a feedback endpoint. A non-zero alternate setting without any endpoint is not supported.

The bTerminalLink field must refer to a Terminal Entity in the topology and its value must be identical in all alternate settings of an AS interface. For Type I formats, exactly one bit must be set to one in the bmFormats field of the AS interface descriptor. Otherwise, the format will be ignored by the driver. To save bus bandwidth, one AS interface can implement multiple alternate settings with the same format in terms of bNrChannels and AS Format Type Descriptor but different wMaxPacketSize values in the isochronous data endpoint descriptor.

For a given sample rate, the driver selects the alternate setting with the smallest wMaxPacketSize that can fulfill the data rate requirements. The driver supports a subset of the control requests defined in ADC-2, section 5. The following table shows the subset that is implemented in the driver. Each subrange describes a discrete frequency, or a frequency range.

Individual subranges must not overlap. If a subrange overlaps a previous one, it will be ignored by the driver. The USB Audio 2. The driver supports one single volume range only. If a feature unit implements single channel controls as well as a master control for Mute or Volume, then the driver uses the single channel controls and ignores the master control.

There is not any specific partner customization that is associated with the in-box USB Audio 2. This INF file entry provided in a update to Windows Release , is used to identify that the in-box driver is a generic device driver.

USB Audio 2. An arbitrary number of channels greater than eight are not supported in shared mode due to a limitation of the Windows audio stack. The example is for a non-composite device with single feature descriptor. If the driver does not start, the system event log should be checked. The driver logs events which indicate the reason for the failure. Similarly, audio logs can be manually collected following the steps described in this blog entry.

If the failure may indicate a driver problem, please report it using the Feedback Hub described below, and include the logs. For information on how to read logs for the USB Audio 2. If you run into a problem with this driver, collect audio logs and then follow steps outlined in this blog entry to bring it to our attention via the Feedback Hub. Audio Drivers Overview.

Privacy policy. Skip to main content. Contents Exit focus mode. Architecture usbaudio2. Audio formats The driver supports the formats listed below. Type I formats FMT-2 2. Audio function topology The driver supports all entity types defined in ADC-2 3. Cyclic paths in the topology are not allowed. Audio streaming The driver supports the following endpoint synchronization types USB-2 5. There is currently limited support for devices using a shared clock for multiple endpoints.

An alternate setting with a format that is not supported by the driver will be ignored. The MaxPacketsOnly flag in the bmAttributes field is not supported and will be ignored. Class requests and interrupt data messages The driver supports a subset of the control requests defined in ADC-2, section 5. Clock source entity For details on this specification, refer to ADC-2 5.
