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 :
- Plugging in an external headset will not mute the internal speakers ( has to be done
manually in alsa-mixer )
That's an unimplemented feature. It shouldn't be too hard to add it if you help debugging well (i.e. you can build and test drivers from HG tree without hitch).
- The PC speaker ( bell ) appears to be permanently muted.
Partly intended (as I dislike it ;)
- The external microphone input does not appear to be working no matter what I do.
Do you mean for recording or analog loopback?
- When recording from the internal microphone the level is very, very low and almost
drowns in static noise.
There are "Mic Boost" and "Front Mic Boost" mixer volumes.
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.
Doh, that's way too old, stone aged. Use ALSA HG version.
