+Subject: ALSA: usb-audio: Add implicit feedback quirk for RODE AI-1
+
+From: David Heimann <d@dmeh.net>
+
+commit 6a3439a417b910e662c666993798e0691bc81147 upstream.
+
+The RODE AI-1 audio interface requires implicit feedback sync between
+playback endpoint 0x03 and feedback endpoint 0x84 on interface 3, but
+doesn't advertise this in its USB descriptors.
+
+Without this quirk, the device receives audio data but produces no output.
