[Bug 617639] [NEW] no sound from microphone on HP Pavalion tx2640er (snd-hda-intel)

[Vitaly Zawullon Katraev]

Public bug reported:

I can`t get any sound from microphone. Trouble isn`t present in Lucid
(but I need manual change some levels in alsamixer to make mic work). On
vanilla kernel 2.6.35 bug also isn`t present (mic works fine in Gentoo
with kernel from kernel.org, but also need change levels in alsamixer to
make mic work).
