* ALSA: usb-audio: work around KEF X300A firmware bugClemens Ladisch2014-02-171-0/+9
| | | | | | | | | | When the driver tries to access Function Unit 10, the KEF X300A speakers' firmware apparently locks up, making even PCM streaming impossible. Work around this by ignoring this FU.

* ALSA: usb-audio: Add a quirk for Plantronics Gamecom 780Takashi Iwai2013-12-201-0/+10
| | | | | | | | | | | Plantronics Gamecom 780 headset has a firmware problem, and when the FU 0x09 volume is changed, it results in either too loud or silence except for a very narrow range. This patch provides a workaround, ignoring the node, initialize the volume in a sane value and keep untouched.

* ALSA: usb-audio: add support for M-Audio FT C600Matt Gruskin2013-02-111-0/+4
| | | | | | | | | | Adds quirks and mixer support for the M-Audio Fast Track C600 USB audio interface. This device is very similar to the C400 - the C600 simply has some more inputs and outputs, so the existing C400 support is extended to support this device as well.

* ALSA: snd_usb_audio: ignore ctrl errors on QuickCam Pro for NotebooksOleksij Rempel2012-06-201-0/+4
| | | | | | | | | | | | | | | | | | This webcam works mostly ok, exept with skype. Skype sends lots of ctrl messages to dynamically ajust record level. If for some reasons it pokes some error every thing goes broken: - first pulseaudio blocks sound for all apps - then video is reseted - then skype freez dmesg has lots of messages like: cannot set freq 16000 to ep 0x86" Setting ignore_ctl_error=1 fixes this problem.
