Subject: [ 07/32] ALSA: usb-audio - Fix invalid volume resolution on Logitech HD webcam c270
Date: Tue, 11 Jun 2013 13:03:06 -0700 [thread overview]
Message-ID: <20130611200127.024269512@linuxfoundation.org> (raw)
In-Reply-To: <20130611200126.214442788@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
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.
