Re: [Alsa-user] ASoC: bytcr_rt5651 - sound on headphones only, no speaker no microphone

Maybe, u can try to contact plbossart (who fix 95681). I saw him give fixes for 
several similar platform, with the quirk related to dmidocede-info.I planned to 
write to him, but just can't find any contact info.

I had a play with a few versions but in that series didn't have any
success. I noted that in the 4.15-rc series the rt5651 driver has been
overhauled, so built and tried that and found it was worse - no sound
at all! It turns out my machine needs one of the flags, MCLK_EN, to not
be set (I've read something which suggests that MCLK_EN is Baytrail-
specific and not something to be done on Cherrytrail). Once that has
been changed I do at least get headphones but still no speakers. I
tried the DMIC, IN1 and IN2 maps the new driver provides but no
microphone on any of them - although I don't know whether this is
because one of the many many mixer controls are set wrongly. I may have
another play with different combinations of recording mixer controls
and see what happens.

Either way, I'll submit a patch to add this machine to the quirk map so
that MCLK_EN is not set by default on this hardware - that way I at
least get to keep the headphone audio.

Many thanks,

Luke

And check if this thread helps, 
https://bugzilla.kernel.org/show_bug.cgi?id=95681Here is a git from plbossart 
(who fix above bug), which is related to his quirks on rt serial sound cards. 
But he said it should be merged into 4.13.

 Hi,

I've a Linx 820 tablet (cherrytrail z8350) which seems to have an
RT5651 codec. Using driver bytcr_rt5651 which is loaded automatically,
sound works fine on headphones, but the speaker output appears to play
(in that the the seconds count up and pavucontrol shows "sound" on the
little graphs) but the output is silent (I've checked it's not muted).
Also, PulseAudio denies there is any microphone on the machine and for
headphones the jack detection doesn't work so the output must be
switched manually to headphones.

Is this likely to be because it needs some of the driver's quirks
settings for the hardware? Are there particular ones it's likely to be
that I should try first? The tablet DMI-identifies it's made by Insyde,
and the code for the the RT5640 suggests they needed several quirks on
that (similar, bay trail) hardware. 

Many thanks for any pointers/suggestions to get me started!
