Re: Low volume since linux 3.19

Hi,

a few weeks ago you wrote a patch for a lifebook T731 which fixed some
wrong BIOS configuration concerning the headphone pin.
A tried the patch with my Lifebook E753 and it worked. The Speaker+LO
setting is gone. In alsamixer only 'Speaker' and 'Headphone' remain.
'Speaker' is muted when I plug in a headphone.
So if I don't get something wrong this is the same issue!?
If it is and you don't mind, would you add the following quirk-patch?

If I got something wrong, please tell me.
