Hello everyone,

Im Travis (wishie) once of the many helpers who man the unofficial #alsa on 
freenode irc network.. I usually spend my time fixing other peoples sound 
issues, but now i have my own.

I have a HP DV2839TX laptop, and i get ALOT of static when recording via the 
inbuilt mic. Also, the mic controls are very strange.. I have (in the Capture 
section of alsamixer).. Digital, Docking Mic, External Mic, Internal Mic.. 
only the "Digital" control seems to effect my recording volume at all. 
Strangely, though, the '* Mic' controls in the PLAYBACK section of alsamixer 
do change the recording properties somewhat (volume being the main factor). 
In any event, i get a rather large amount of static, no matter what mixer 
settings i try. This isnt a problem in the 'other' OS.
