Re: [gentoo-user] Anyone get Acer laptop internal microphone working in Gentoo?

[Hung Dang <hungptit@gmail.com>]

I guest you may need to play around with the mixer (KDE,GNOME) or
alsamixer to enable internal microphone. I have to enable
recording/capture in GNOME volume applet to make the internal microphone
worked on my D630.

Hope this help,
Hung
