Dear NXP team,
I use imx8mp-evk with linux-imx lf-5.10.72-2.2.0
There is an usb uac2 error(Source/Sink driver does not working) with Windows10 PC.
So, I want to check using latest linux-imx.
Please let me know the latest linux-imx version and how to merge.

Hi fu,
Thanks for the patch.
Windows sound driver working!!
Actually, I want to play 'wav' on Windows via uac2. (aplay on imax8mp > uac2 > Windows PC)
But There is "aplay: pcm_write:2058: write error: Input/output error"
Could you tell me the solution?
1. imx8mp g_audio setting
2. arecord wav file on imx8mp (using 2-channel PDM mic)
arecord -f S16_LE -D plughw:1,0 -t wav -r 48000 -c 2 -d 10 -vvv ./sample.wav
3. aplay test error
I can play on device side and record on windows without error, here are my steps:
1. On windows, set uac2 microphone as default device
2. On windows, use Voice Recoder to record
3. On device side, use aplay to play:
aplay -Dhw:UAC2Gadget audio_l48k16b2c.wav -N
