CONFIG_USB_AUDIO: Audio Gadget

General informations

The Linux kernel configuration item CONFIG_USB_AUDIO has multiple definitions:

Audio Gadget found in drivers/usb/gadget/legacy/Kconfig

The configuration item CONFIG_USB_AUDIO:

• prompt: Audio Gadget
• type: tristate
• depends on: CONFIG_SND
• defined in drivers/usb/gadget/legacy/Kconfig
• found in Linux kernels: 3.17–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.11, 6.12-rc+HEAD
• modules built: audio, g_audio, g_audio

Help text

This Gadget Audio driver is compatible with USB Audio Class specification 2.0. It implements 1 AudioControl interface, 1 AudioStreaming Interface each for USB-OUT and USB-IN. Number of channels, sample rate and sample size can be specified as module parameters. This driver doesn't expect any real Audio codec to be present on the device - the audio streams are simply sinked to and sourced from a virtual ALSA sound card created. The user-space application may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host.

Say "y" to link the driver statically, or "m" to build a dynamically linked module called "g_audio".

USB Audio support found in drivers/usb/class/Kconfig

The configuration item CONFIG_USB_AUDIO:

• prompt: USB Audio support
• type: tristate
• depends on: CONFIG_USB && CONFIG_SOUND && CONFIG_OBSOLETE_OSS_USB_DRIVER
• defined in drivers/usb/class/Kconfig
• found in Linux kernels: 2.5.45–2.5.75, 2.6.0–2.6.16
• modules built: audio, g_audio, g_audio

Help text

Say Y here if you want to connect USB audio equipment such as speakers to your computer's USB port. You only need this if you use the OSS sound driver; ALSA has its own option for usb audio support.

To compile this driver as a module, choose M here: the module will be called audio.
