Subject: [PATCH] ALSA: usb-audio: Add mic volume fix quirk for Logitech Quickcam Fusion
Date: Fri, 29 May 2015 19:50:56 +0900	[thread overview]
Message-ID: <1432896656-3228-1-git-send-email-wsa@the-dreams.de> (raw)

Fix this from the logs:

usb 7-1: New USB device found, idVendor=046d, idProduct=08ca
...
usb 7-1: Warning! Unlikely big volume range (=3072), cval->res is probably wrong.
usb 7-1: [5] FU [Mic Capture Volume] ch = 1, val = 4608/7680/1
