can't use microphones on HP Pavilion tx1000

[Johnny Izzo]

In the previous installed distro in AlsaMixer (v.1.0.22), under recording i had "Capture" and "Input Source". From input source i selected front mic (external audio jack) or ATAPI mic (computer internal mic).

Now installed latest Pangolin, in Alsamixer (v.1.0.25) under recording i have: "Mic Boost", "Capture" and "Internal Mic Boost".
I guess it should automagically connect the mics, because on plugging/unplugging the mic boosts change.
But recording internal mic is quiet and recording external mic is noise.
