[alsa-devel] Intel HDA / AD1986A problems

 Configuration : Lenovo 3000 N100 laptop with Intel HDA / Anlog Devices AD1986A
soundcard running CentOS5.0 with 2.6.18-8.1.8.el5 kernel ( uses 1.0.12rc1 based
alsa driver ).

 The driver works with the model=laptop-eapd option except for a few things :

1)  Plugging in an external headset will not mute the internal speakers ( has to be done
manually in alsa-mixer )

2)  The PC speaker ( bell ) appears to be permanently muted.

3)  The external microphone input does not appear to be working no matter what I do.

4)  When recording from the internal microphone the level is very, very low and almost
drowns in static noise.


 Any easy way to fix the above ? Number 4 in particular ?  I've tinkered with backporting
what I thought were relevant differences between the latest patch_analog.c and the one
used in the kernel I have (alsa-driver 1.0.12rc1 ) but I see no difference.

 Any other way to tweak or reconfigure the hardware ? Enable microphone boost ??
Looking at /proc/asound/card0/codec#0 makes me believe that the hardware has several
unused or permanently disabled features.

 This particular laptop has a model number which differs slightly from the one listed in
patch_analog.c ( 0768-6KU instead of 0768-4JU ).  Not sure if is relevant. 

 And finally a ( somewhat ) related question : Is it possible to get the sound card to
work with the slmodem package to drive the built in modem ???
