    There are 2 analogue audio jacks: for microphone and for speakers.
    There is aslo HDMI port from ATI 5470.

    Another interesting point is that HD-Audio-Models.txt does not lists any Acer model for ALC272, so I tried "auto" but with no success.

    Try 3stack-dig:
    Code:
    options snd-hda-intel model=3stack-dig
    Reboot.

    Also 3stack-6ch, 3stack-6ch-dig

    Thanks for quick reply, lidex!

    I've tried 3stack-dig, 3stack-6ch and 3stack-6ch-dig. Each provided the choice if input source: Mic and Front Mic. I've tried both of them for each model. But the problem is still present:

    1. There is a "chucklink" during audio call, so the other person can hardly understand you;
    2. Videocall kills the microphone.

    Ubuntu developers confirmed this bug.

    I'm thinking it may have something to do with the fact that snd-hda-intel is being used by both devices. Are you using hdmi and if not can it be disabled? What profile are you using in 'Sound Preferences'?

    I don't use HDMI and I've tried disabling it. I've even tried to remove proprietary ATI driver, but with no success

    Here are screenshots of my sound configuration:

    I've managed to solve the problem with following workaround:

    1. replace Empathy with Skype
    2. delete pulseaudio (this removes some things like sound indicator)
