    [SOLVED] Linux Mint on Acer Extensa 5220 laptop - no sound capture

    Hi,
    I am unable to capture sound in sound recorder or GTK RecordMyDesktop.
    Does anyone have a solution?
    I use Linux Mint Elyssa.

    I tried alsamixer in the command prompt but still no luck.

    Please help.

    Thanks.

    Re: Linux Mint on Acer Extensa 5220 laptop - no sound capture

    To get sound working properly on my Extensa 5620 (Ubuntu 8.04), same chips as yours, I had to edit alsa-base file.

    sudo gedit /ect/modprobe.d/alsa-base
    Add the line

    options snd-hda-intel model=acer

    Restart X, or reboot.

    Internal mic is noisy here, but that's probably because it's sitting on a cooler pad.

    Hi,
    I added that line.
    I tried to capture sound in Audacity, I just get noise.
    Should it have been added at the end of the alsa-base file, or does it matter where the line is added?

    I have only recorded off of Line In previously.
    After playing around a bit I found a possible solution.
    Dbl click the sound icon, opening ALSA Mixer.
    Be sure you have the correct input devices enabled.
    See screen shots.
    Select "Edit" "Preferences".
    Go to the Edit tab and select the correct input device.
    The levels must be set now.
    Then "File" "Change Device" and select either of the capture devices.
    Both worked noiselessly for me.

    After select Capture the only level device you will have is the Master.

    Just one more thing(as Columbo used to say):

    What are your settings for the pictures attached?

    Thanks again.

    Re: Linux Mint on Acer Extensa 5220 laptop - no sound capture

    I leave everything maxed as you have it.
    If the recording starts clipping, distortion because input levels are too high, you'll simply have to adjust to suit.

    Also, if you're getting too much ambient noise from the room with Audacity, or what ever program you're using...
    Turn down the input gain in ALSA Mixer and turn up the recording gain in the program.
    It becomes a balancing act.
    Ideally, you want the recorded level to almost clip, but stop just short.

    The discerning ear knows that every room has different acoustic qualities.
    Even moving the microphone(s) within a given room will effect the end recording.

    I don't know if Mint offers a real-time kernel.
    If so I recommend installing and booting it to do recording.
    Then return to the generic kernel for normal PC use.
    Or dual boot Mint and UbuntuStudio
