USB PnP Sound Device] on usb-0000:00:1a.0-1.4/input3 [ 9922.872746] usbcore: registered new interface driver snd-usb-audio called "CSL Stormrider Wired Headset", playback becomes suddenly inaudible when the volume slider in the unity sound preferences (accessed via indicator → loudspeaker icon → sound settings) is set to below circa 40 %. Setting to above ~40 % restores playback volume to what you would expect. In alsamixer, the same problem occurs when going from volume level 02 to volume level 01. At alsamixer level 02, the volume is about what you would expect when setting a volume slider to about 40 %. This is annoying since 40 % can already be rather loud.
