Hello,
I am trying to use my device as a sound card and enabled
CONFIG_USB_AUDIO. However I don't know what kind
of device node should be added in the machine file?
I just want to record whatever is coming into the USB played
back by the host over USB.
I could get my device to be detected as a sound card i.e.
USB_AUDIO_CLASS in my ubuntu machine.
My understanding of USB audio is very less so I thought
below change should be sufficient.
Below are the only changes which i have done to enable USB_AUDIO.
Machine file:
{
.name = "something_random",
.stream_name = "USB Capture",
.cpu_dai_name = "snd-soc-dummy-dai",
.codec_dai_name = "snd-soc-dummy-dai",
.codec_name = "snd-soc-dummy",
.ignore_suspend = 1,
},
drivers/usb/gadget/u_uac1.c :
#define FILE_PCM_PLAYBACK "/dev/snd/pcmC0D0p"
#define FILE_PCM_CAPTURE "/dev/snd/pcmC0D0c"
in defconfig
CONFIG_USB_AUDIO=y
Please let me know if I am doing anything wrong.
Thanks,
