Thread: No Mic Output Selection In Kmix

    Default No Mic Output Selection In Kmix


    I've been running PCLinuxOs 2007 on my desktop for the past year and
    just installed OpenSUSE on my hp laptop.Kmix in PCLinux presents three
    tabs: input, output, and switches. These tabs aren't present in the kmix
    mixer window I see in SUSE. What is happening is when I speak into the
    microphone I'm hearing myself through the speakers.... very annoying
    when on Skype. I addressed this on my desktop by turning the mic setting
    under the output tab all the way down. Anyone have a solution to my
    dilemma?

    The mixer with the KDE4 desktop has a menu item which allows one to add
    additional controls to the mixer.

    Thank you for your reply. I had found that feature and added the mic
    controls to the mixer window, but mic output doesn't seem to be an
    option..... only the mic input.

    Why would you want a mic output?

    I need to see the mic output selection so I can turn it off. The default
    seems to be on. That's why I'm hearing myself through the speakers. I
    would like to have mic input on, mic boost on, and mic output off. I've
    accomplished the first two but not the third.

    I do not know about PCLinuxOs 2007 , but in most Linux versions I
    thought that (hearing yourself thru the speakers) was known as loopback?


    Which version of openSUSE are you running? If running openSUSE-11.1
    you could, with your PC connected to the internet, type:
    ::/usr/sbin/alsa-info.sh::
    and that will provide a URL (if it asks to update, you may need to
    re-run it as root to ensure the update works). Please post here the
    output URL you get after a successful run of the script.

    Thank you for taking the time to help. I ran Alsa-info.sh as su and it
    did update. The resulting URL is http://tinyurl.com/8mre36

    I don't see anything obviously wrong there. I do note your PC has a
    Cx20468 (uses the snd_ali5451 kernel module). do you get this mic
    effect with arecord? if not, then it could be a skype problem. You can
    run arecord as follows, typing in a gnome terminal or a kde konsole:
    ::arecord -d 10 myrecording.wav::where "-d 10"
    specifies a 10 second recording. Record 10 seconds there and then a
    play back "myrecording.wav" with a nominal player. While recording, do
    you still hear your voice being looped back to you?

    It may be that your sound config is not properly configured by alsa. I
    do not see any options specific to the CX20549, although there are some
    conexant model options in the ALSA-Configuration.txt list for 1.0.18a of
    alsa:
    Code:
    --------------------
    Conexant 5045
    laptop-hpsense Laptop with HP sense (old model laptop)
    laptop-micsense Laptop with Mic sense (old model fujitsu)
    laptop-hpmicsense Laptop with HP and Mic senses
    benq Benq R55E
    test for testing/debugging purpose, almost all controls
    can be adjusted. Appearing only when compiled with
    $CONFIG_SND_DEBUG=y

    Conexant 5047
    laptop Basic Laptop config
    laptop-hp Laptop config for some HP models (subdevice 30A5)
    laptop-eapd Laptop config with EAPD support
    test for testing/debugging purpose, almost all controls
    can be adjusted. Appearing only when compiled with
    $CONFIG_SND_DEBUG=y

    Conexant 5051
    laptop Basic Laptop config (default)
    hp HP Spartan laptop
    --------------------
    I do not know if any of those are applicable to your laptop. But it
    would not hut to test them one at a time. I can provided a recommend
    syntax for an edit to your /etc/modprobe.d/sound file to test them.
    Accordingly, can you provide the output of:
    Code:
    --------------------
    rpm -qa | grep alsa
    rpm -qa | grep pulse
    uname -a
    cat /etc/modprobe.d/sound
    --------------------

    Yes, the mic is heard through the speakers at all times when plugged in;
    even when Skype isn't running. If I tap on it, blow, whistle, speak, the
    sound is coming right through them.

    You mentioned the configuration of Alsa. When setting up my desktop I
    ran something called alsaconfig. I don't see that listed in the SUSE
    repositories. Is that a tool that isn't necessary with this
    distribution?

    results for rpm -qa | grep alsa:

    which you do not appear to have installed.

    > alsa-plugins-1.0.18-6.12Are you certain you did not forget to copy any applications as a result

    of typing: "rpm -qa | grep alsa" ? I'm really surprised alsa-utils
    is not present, as that is installed by default. It provides both
    alsaconf and alsamixer.

    I recommend you also install alsa-tools and alsa-utils, reboot and see
    if you have any additional mixer selections.
