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 ???
