Ack, BYT_RT5651_DEFAULT_QUIRKS is:

#define BYT_RT5651_DEFAULT_QUIRKS       (BYT_RT5651_MCLK_EN | \
                                         BYT_RT5651_JD1_1   | \
                                         BYT_RT5651_OVCD_TH_2000UA | \
                                         BYT_RT5651_OVCD_SF_0P75)

So compared to the quirk from the original patch that will add:

BYT_RT5651_MCLK_EN
BYT_RT5651_OVCD_TH_2000UA
BYT_RT5651_OVCD_SF_0P75

Since you have working jack-detect you will definitely want the latter 2
which will make headset vs headphones detection work and will add
button-press detection for headsets.

BYT_RT5651_MCLK_EN is also a quirk which you almost always want,
the sole exception is boards where the mclk is not connected which
are very rare. Boards where the mclk is not connected are easy to
spot, since they will not work at all when setting BYT_RT5651_MCLK_EN,
so if things work with BYT_RT5651_DEFAULT_QUIRKS then setting
BYT_RT5651_MCLK_EN is the right thing to do.

Tl;DR: use (BYT_RT5651_DEFAULT_QUIRKS | BYT_RT5651_IN1_IN2_MAP) as
Pierre-Louis suggests.

Regards,

Hans
