Samsung Q1 (Analog Device AD1986A Codec) High Pitched Tone & Inability to Record

Samsung Q1 (Analog Device AD1986A Codec) High Pitched Tone & Inability to Record

[Allyn, Mark A]

Hello:
 
I have a Samsung Q1 Ultra Mobile PC with an Analog Devices AD1986A Codec

(according to /proc/asound/card0/codec#2). 
 
We are using the Alsa 1.0.13 driver. We are unable to record using 
the built-in internal microphones. 
 
Also, when we try to use the internal speakers, we are getting a 
high pitched sound (above 9 Khz) from the speakers. Using headphones 
plugged into the headphone jack seems to work okay.
 
Has anyone been able to get 1.0.13 working properly on the Samsung Q1?
 
Thank you
 
Mark Allyn

Hey, Mark.

Have you tried a newer alsa snapshot?  There has been a lot of changes
since 1.0.13.  You can get a daily snapshot here:
ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver/
Start with that version, and try some of the different model parameters
(model=laptop and model=laptop-eapd) to see which works best.

Also, please post the subsystem id for that chip.  You can get it with
'lspci -s 0:1b -vn".  I'll get it added to the driver if it isn't
already listed.
