    Smile Mic not working in Ubuntu 12.04 Beta 2 - Lenovo G470

    Hi all. I used a Lenovo G470 laptop (Core i5 2410M processor, AMD Radeon 6370M and 2GB DDR3 RAM) and I installed Ubuntu 12.04 Beta 2.
    I can't get the microphone to work. I encountered this type of issue before in my old Acer Aspire One with Ubuntu 10.04/10.10, and installing PulseAudio Volume Control and tweaking a little solves the problem. I tried the same solution to no avail.

    cat /proc/asound/card0/codec* | grep Codec gives the following result:
    Codec: Conexant CX20590
    Codec: Intel CougarPoint HDMI

    Does anybody encountered a similar problem? Any help will be greatly appreciated.

    Same here, with a Sony Vaio vpceb27fd from 11.10 to 12.04. Mic worked before, its not muted in alsamixer but when I open sound settings I show no device under input. External speakers work, and headphones do not.

    I was hoping these sound issues would have been less of an issue. I know its still beta, but only a few days away from a real release..

    Also reporting the same issue on a Dell XPS 14. Everything was working fine in Oneiric.
