ALSA: usb-audio: mixer: volume quirk for ESS Technology Asus USB DAC
The Asus USB DAC is a USB type-C audio dongle for connecting to the headset and headphone. The volume minimum value -23040 which is 0xa600 in hexadecimal with the resolution value 1 indicates this should be endianness issue caused by the firmware bug. Add a volume quirk to fix the volume control problem. Also fixes this warning: Warning! Unlikely big volume range (=23040), cval->res is probably wrong. [5] FU [Headset Capture Volume] ch = 1, val = -23040/0/1 Warning! Unlikely big volume range (=23040), cval->res is probably wrong. [7] FU [Headset Playback Volume] ch = 1, val = -23040/0/1 Signed-off-by: Chris Chiu <chiu@endlessm.com> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20200526062613.55401-1-chiu@endlessm.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
