Greetings,

Related to the microphone TOO low issue (-50db): on a Dell XPS M1330.
Compiling ALSA from sources - amd64 arch.
I downloaded ALSA snapshot dated 10-Jan-2007 - it already has the patch + also 
explicitly detects now the M1330 model.
But the mic is still to low, so I searched in patch_sigmatel.c for the 
"sensibility" patch.... (does it has to make the mic more sensitive?)
-               spec->dmux_nid = 0x1c;
+               spec->dmux_nid = 0x1b;
But dmux_nid was removed, there is a member called dmux_nids - which is a 
vector and contains in this case the patched element - 0x1b.
While have no ideea about these codes and dmux_nids - I think that all your 
changes are patch are included, and after that the structures slight 
refactored... but the mic is still unusable. Only thing you can do with it is 
record with audacity and normalize volume to -6db...?  By no means u can't use 
kopete / skype with this!
So I guess this is still open?

Thanks!
