It was fixed the master volume keep lower. [Some background: the patch essentially skips the controls of a couple of FU volumes. Although the firmware exposes the dB and the value information via the usb descriptor, changing the values (we set the min volume as default) screws up the device. Although this has been fixed in the newer firmware, the devices are shipped with the old firmware, thus we need the workaround in the driver side. -- tiwai] Signed-off-by: Kailang Yang Cc: Signed-off-by: Takashi Iwai --- sound/usb/mixer_maps.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'sound/usb') diff --git a/sound/usb/mixer_maps.c b/sound/usb/mixer_maps.c index ddca6547399b..1f8fb0d904e0 100644 --- a/sound/usb/mixer_maps.c +++ b/sound/usb/mixer_maps.c @@ -348,6 +348,16 @@ static struct usbmix_name_map bose_companion5_map[] = { { 0 } /* terminator */ }; +/* + * Dell usb dock with ALC4020 codec had a firmware problem where it got + * screwed up when zero volume is passed; just skip it as a workaround + */ +static const struct usbmix_name_map dell_alc4020_map[] = { + { 16, NULL }, + { 19, NULL }, + { 0 } +}; + /* * Control map entries */ @@ -430,6 +440,10 @@ static struct usbmix_ctl_map usbmix_ctl_maps[] = { .id = USB_ID(0x0ccd, 0x0028), .map = aureon_51_2_map, }, + { + .id = USB_ID(0x0bda, 0x4014), + .map = dell_alc4020_map, + }, { .id = USB_ID(0x0dba, 0x1000), .map = mbox1_map, -- cgit v1.2.3
