The patches have been added to the BSP in meta-renesas-rcar3 in master and eel branches.

I understand USB-BT is used for music player, not speaker. Thanks.

FYI, we replicated this on several m3ulcb's today with USB-BT a2dp audio streaming from the phone playing out the on-board audio.

,   Thx.

It's just for your info. We has this jaggy noise only micro phone output on M3. If you use USB-audio or USB-BT, it is not happened. These tree patches are related audio driver on M3 board, so USB-audio is not changed.
