At device side, in driver/usb/gadget/Kconfig, it says before for CONFIG_USB_AUDIO ------------------------- 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. ------------------------- My question is: at device side, how to configure sink/source for UAC2 virtual ALSA sound card (hw:2,0, UAC2_Gadget)?At OS level, select the UAC2 card like any other - Control Panel -> Sound settings. You want to select the same Card on Host as well as Gadget side. -Jassi
Thanks for your reply. At the device side, should I do something to redirect the virtual sound card to a real one?
