This is a note to let you know that I have just added a patch titled ALSA: usb-audio - Fix invalid volume resolution on Logitech to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 4a7adb192b508d9208369c49852e6b0261fb7542 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Wed, 5 Jun 2013 08:35:26 +0200 Subject: [PATCH] ALSA: usb-audio - Fix invalid volume resolution on Logitech HD webcam c270 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 11e7064f35bb87da8f427d1aa4bbd8b7473a3993 upstream. USB audio driver spews an error message when probing Logitech HD webcam c270: ALSA mixer.c:1300 usb_audio: Warning! Unlikely big volume range (=6144), cval->res is probably wrong. ALSA mixer.c:1304 usb_audio: [5] FU [Mic Capture Volume] ch = 1, val = 1536/7680/1 Obviously the device needs a fixed volume resolution (cval->res = 384) like other Logitech devices.
