From 05b9afd5b711b284c17f657495dc08f4a6f6e7e9 Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Tue, 19 Jun 2012 22:21:18 +0200 Subject: ALSA: snd_usb_audio: ignore ctrl errors on QuickCam E3500 if this cam is pluged in, pulse audio can't initiate capture device. dmesg has lots of messages like: "cannot set freq 16000 to ep 0x86" Setting ignore_ctl_error=1 fixes this problem.
