Thread: Setting mic in PulseAudio

  1. #1

    Default Setting mic in PulseAudio

    When I first installed 11.4 I was unable to access the usb webcam mic on Skype. I use Tumbleweed and after a couple of KDE updates I was able to access the webcam mic in Skype. I did this by setting the webcam mic as the first device to use in either pavucontrol or systemsettings>multimedia>phonon>audio capture. There have been many KDE updates since then and now I am back to having no mic in Skype. I will set my webcam mic as described above but pavucontrol will no longer save my changes. It is permanently stuck using internal audio analog stereo as the first capture device. My webcam mic is listed but it is four down on the list and Skype will not access it.

    How can I get pavucontrol to save my preferences?

    Thanks,

    Dave

    What is the issue here ? Is the issue that your webcam mic no longer will pickup audio in Skype and no longer record audio ? or is the issue that pavucontrol will no longer save your USB mic settings in Skype ?

    Note USB mic settings for Skype should be saved in Skype (not in pavucontrol).

    They are both interconnected. The webcam mic will not function unless it is listed in the top position. I cannot get pavucontrol to save my changes placing the webcam mic in the top position.

    Also note that Skype only has one mic option which is pulseaudio server (local).

    Please be certain that when using pulse audio, you select to show ALL streams/devices.

    Can you provide screen prints of your puavcontrol tabs for : configuration, input devices, recording. Again, ensure you select to show ALL streams/devices from the SHOW.

    Just how is the webcam mic wired? Is it treated as a USB mic ? What is the output of:
    Code:
    lsmod | grep usb
    What is the output of:
    Code:
    arecord -l

    Sorry for the delay, I was out of town. Here is what I get when I run lsmod and arecord:

    dave@Voyager:~>

    The dialogue in system settings shows both a webcam camera and webcam audio usb option along with the other options. In pauvcontrol only the webcam camera option is listed along with the internal audio option. Pauvcontrol does not have a way to change the priority order of the devices. This is accomplished in the system settings dialogue. The system settings dialogue is what is not working properly and not allowing me to save my preferred device options.

    I have taken screen shots of both pavucontrol and the system settings dialgoues but cannot figure out how to upload them to this site without going through youtube, facebook, etc which is not an option for me.

    Thanks,

    Dave

    I typically post my images to Fast, Free Image Hosting - ImageBam and then I select the "BB Code" tumbnail option and post here the code they give for the image. I find it works well.

    According to that, your USB webcam is hw:1,0

    What happens if you try to record with:
    Code:
    arecord -D hw:1,0 -vv -f cd test.wav
    and replay the file test.wav with a media player ?

    I uploaded the photos as you suggested, thanks. The urls are:

    I also tried the command you suggested. There was no sound recorded. This mic was working a couple of weeks ago until a KDE upgrade. It has not worked since. The camera is working. Here is the output from the command:

    There was a kernel upgrade with the KDE upgrade. Could it be possible they broke the phillips (pwc) module?

    Thanks again,

    I don't understand this reference to a KDE update.

    I'm sorry to read you have not succeeded yet.

    Please, am I asking for too much information and thus confusing you? I ask because you are providing different information than what I requested, and hence I am thinking I have confused you.

    Here is what I asked:

    Quote Originally Posted by oldcpu View Post

    You provided only "input devices" screen print, (I could not find the configuration tab nor recording tabs screen prints I asked for) and you did not follow my request to show "ALL streams / devices" from the SHOW.

    Anyway, FORGET that, as it is a mute point.

    Something more important follows ...

    You mentioned you updated KDE4. To what version ?

    If to a non-standard SuSE-GmbH version, then I'm also thinking, given your comment about updating KDE, that I should leave this thread.

    Sorry, but its a matter of principle to me.

    I'm a volunteer. Not paid. My experience is such KDE updates cause more problems for sound than they are worth for many users who do not understand the KDE sound system. Hence I myself refuse to do such updates on my own PC, and hence I hope you understand since I don't want the annoyance (that can be caused by such KDE updates) on my PCs (as its irrating when not working), I am very reluctant to be dragged into someone elses KDE update efforts in area that I don't like doing myself. I've never liked doing KDE updates.

    IMHO those who want to update KDE and go beyond the tested SuSE-GmbH stock version are into software that I don't like to provide volunteer support.

    On a final note, my guess, thou, is you have either pulse audio configured wrong, or your mixer misconfigured, or its a problem with a non-nominal KDE4 from your update (the sort of update I refuse to do). I can not tell which nor do I want to spend time figuring out which.

    I'll let someone else who likes to play with updated KDE dive in to this thread.

    Hopefully someone will help as many people disagree firmly with my KDE view.

    Good luck and Best wishes.
