From 62abd092f97b33a33fcdb98c30bc01f2b1c55d04 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 23 Nov 2020 09:53:45 +0100 Subject: ALSA: usb-audio: Add implicit_fb module option A new module option, implicit_fb, is added to specify the driver looking for the implicit feedback sync. This can be useful for a device that could be working better in the implicit feed back mode and user wants to test it quickly. When this works, we can add the quirk entry easily.
