    Asus Eee 1201n Microphone

    HI folks,

    Hope there is some advice out there.

    I have an Asus Eee 1201n which is running Karmic very well, had a couple of issues with wireless but thanks to Realtek support for Linux they released a driver that works perfectly with more recent kernels (2.6.31-20). Quick side note, if you are running this netbook do yourself a favor and try "rtl8192se_linux_2.6.0015.0127.2010" before you use NDISWrapper etc.

    OK, back on topic. Last thing I have left is the built-in microphone (NVIDIA ION HD Audio). GNOME Alsa Mixer sees it, so does the GNOME sound panel, Skype sees it as well but no go. I have tried Alsa backports to no result. There is a thread in these forums for a script (Alsa upgrade script) and although I thank the dude who wrote it I am paranoid as he explicitly says:

    "The script is not in line with Debian/Ubuntu rules for package handling. It just overwrites existing files. You won't see any changes on the ALSA package-ids within Synaptic!"

    And this scares me just a bit. I am about to try this script as I am just plain tired of Skype with a BT headset (my wife calls me a cyborg) so before I kick it off I thought I would ping the "Gurus" and see if there are any other suggestions out there.

    Thanks in advance!

    Hank.

    Solved... Installed the pulseaudio utility and set the 2nd mic channel to 0.

    Hello,

    I have the same computer and the same problem. Could you please give me the steps you took to installing pulseaudio util and using it. I am a noob but am learning a lot. Sadly I just can't figure out how to set those settings to zero like you said.

    Thank you for your help and time!

    Sure man, hope this helps:

    I am not sure of your level of Linux experience so don't take any offense if these instructions are too verbose.

    1) Open Synaptic Package Mananger from System->Administration
    2) Search for a package with a name like "linux-backports-modules-alsa-karmic-generic" (it will have the name of your distribution, karmic if you have 9.10, lucid if you are running the 10.04 LTS Beta etc.) and mark it for install
    3) Still in Synaptic, search for a package called "pavucontrol" (PulseAudio Volume Control) and mark it for install as well
    4) Hit "Apply" and after the packages have downloaded and installed, reboot linux
    5) Once you log back in, go to Applications->Sound & Video and run "PulseAudio Volume Control"
    6) Click the "Input Devices" tab and you will see your mic but it will have two channels (stereo) a Front Right and Front Left. Well this is just plain wrong! A mic is a mono device, so go ahead and set that Front Right slider all the way to "Silence" (you can leave Front Left at about 80-90%)

    Exit PulseAudio Volume Control and you should now have a working mic in all applications including Skype if you use it.

    Cheers,

    Hank

    Thanks Hank,

    I have an ASUS Eec PC 1001P.

    Following your advice got my sound recorder to record sound. However Skype still does not record.

    Hi Mike,

    Glad we got something working

    Quick question, under Skype->Options->Sound Devices, what does it show? It should show "PulseAudio Server (local)" for all options, also I found that "Allow Skype to automatically adjust my mixer levels" does NOT WORK! In order for my mic to work in Skype I have to un-check that option.

    Also what version of Skype are you using? I am on Beta 2.1.0.81.

    Let me know if this helps, if not we can take a deeper look.

    Hi Hank,

    Apologies from the following long post but it may help other forum members.

    I'm also on Skype Beta 2.1.0.81.

    I believe that it is not a Skype problem but a PulseAudio one.

    Skype did show "PulseAudio Server (local)" for all options. There were no other options.
    I unchecked "Allow Skype to automatically adjust my mixer levels".
    No recording made from inbuilt microphone (using Echo / Sound Test Service"

    Ubuntu System > Preferences > Sound > Input shows no Input level bar movement when I speak into builtin microphone.
    However when I plugged in an external microphone the bars moved.
    Great - It worked and so did Skype sound recording.
    So I looked at Ubuntu System > Preferences > Sound > Input > Choose a device for sound input and it showed "Internal Audio Analog Stereo"
    That looks correct for the builtin mike. So I ask myself why does external one worK???
    Hardware showed Internal Audio 1 Output/1 Input Analog Stereo Duplex.
    When I click Sound Effects > Choose an alert sound: I get the appropriate sound I click like Default or Bark, etc.

    When I boot ASUS Express Gate (which I believe is a tiny Linux based distro) and select Skype I found that the Sound devices that worked are
    Sound In: HDA Intel (hw:Intel.0)
    Sound Out: HDA Intel (hw:Intel.0)

    Maybe I have a sound driver problem?.

    So being a retired R&D system software engineer I had a play around:
    Using Ubuntu Software center
    - I removed all PulseAudio stuff - problem unsolved.
    - Installed Default Sound Card (ALSA) - problem unsolved
    - Installed GNOME ALSA Mixer. I noticed Mic Boos was at bottom of slider and balance (left right) could not be moved. Capture Rec was ticked - problem unsolved. I unticked Rec - problem unsolved. I reticked Rec - PROBLEM SOLVED. SKYPE RECORDING WORKS ON INTERNAL MIKE!!!
    Just to be sure I rebooted Ubuntu.
    Skype recording still works on internal Mike.
    Tried my external boom mike It works but lots of buzzing even at no or less than amplified input. It is fine on my old laptop but needs input amplified.

    Regards
    Mike

    Thanks for posting this back Mike, that's great news!

    My fault entirely for not adding that I have ALSA Mixer installed as well, I did not have to check/un-check the Capture Rec tickbox to get mine working, but then again I had ALSA mixer installed early in my attempts to rectify the problem so perhaps I had done that a few times before getting the ALSA backports installed.

    Always nice when folks post back their solutions.

    There is just far to much confusion in the Linux World right now in Sound and Video APIs in general, so much so that we can't even get proper Hardware Acceleration in Flash for Linux because they can't pick a proper API.

    Nice paper on the sound API issue at this link: http://0pointer.de/blog/projects/gui...ound-apis.html

    From 2008 but still applies today...

    Think I am going to spend a bit of time removing the rust from my C/C++ and get a bit more involved, just hope I can do more good than harm

    You are a jolly good egg.

    It is really sad that the vast majority of home Personal Computer users use Microsoft operating systems.
    Such systems have all the security flaws and performance degradation inherent in the design of Windows since XP and maybe before.
    The concept and implementation of the Windows Registry and of the DLL hell is in my opinion the Achilles Heel of Redmond's outpourings.
    I've spent a lot of my retirement bailing out friends and neighbours from broken Microsoft systems.

    The latest victim (a lady friend of a friend) of Microsoft opsys vulnerabilities (XP) had 170 infected files, seven or more different types of viruses including a rogue dialler, keytroke recorder, trojan horse, email worm and two rootkit viruses.
    With the help of online forums and use of Malwarebytes, etc., I was able to clean up her sick XP system but the rootkit viruses remained.
    I was able to save all her irreplaceable data onto an external USB HDD by booting from an Ubuntu live CD.
    Her desktop PC had an XP recovery partition so I was able to reset the PC to factory condition and then installed her vital applications and restored her data. I had earned the big hug she gave me


    One has to recognise Microsoft's formidable success as a result of their aggressive marketing. A pity that IBM did not target and market OS/2 to home users as well as Companies.

    I too, as a retired R&D software engineer, would like to contribute to Ubuntu's success. I guess that IBM Assembler does not have much call today but I can hack it a bit in PHP.

    All the best

    Re: Asus Eee 1201n Microphone

    Unfortunately, neither of these solutions worked for me. I can record sounds in the "Sound Recorder" application, but not in Skype. I tried using the PulseAudio and GNOME ALSA Mixer, but neither worked. Any other suggestions?
