** Description changed: - this bug is for tracking purpose. + [Impact] + On the Dell WD15/19 Dock station, there is a USB audio card, and + a headset audio jack routes to this audio card. We found if we plug + some specific headset (non-iphone type headset), we could not record + any sound from headset-mic even we set the input volume to max. + + [Fix] + Improve the ucm for the audio card in this Dock, let the driver mixer + value be adjustable, then we could adjust the input volume from driver + side. + + [Test Case] + plug various types of headset to the WD19 and WD15 dock stations, and + adjust the input volume from gnome, check the input volume in the driver + by running amixer, found the input volume is changed in the driver; + record the sound from headset-mic, it could record the sound from all + headsets we tested. + + [Regression Risk] + It could make the PA fail to load the ucm on the machines with Dell + WD15/WD19 dock station, then users only see analogue output/input from + gnome-control-center instead of usb-speaks usb-lineout and usb-mic. + But this possibility is very low since we have tested the patch on WD15 + and WD19 dock, all worked very well.
