Alsa: how to controll the auto mute feature?

Hi,
I have a slight problem with my laptop.
I have a headphone jack, a analogue volume control wheel and my normal speakers.
What I like to have is this:
Plug in headphones => sound only from headphones
No headphones plugged => sound from main speakers (I do not care if sound is still put onto the headphone jack as I would not here it one way or the other)
Right now, this is not working out of the box.
Plugging in my headphones mutes the speakers, great, but it does not unmute my headphones so I hear nothing until I go into alsamixer and unmute my headphones.
This would not be a problem but once I unplug my headphones, alsa mutes them. Ergo, everytime I unplug and plug my headphone I have to unmute them in the alsa mixer.
Can someone tell me where I can controll this behaviour to fix this?
I have seen multiple entries for pulseaudio (which I am not usign right now) or references to a auto-mute button in alsamixer which I do not seem to have in mine.
With best regards,
p90

@nomorewindows See if the same happens with power_save and power_save_controller parameters set to 0.
@p90 did you try replugging twice or more times? One more thing you can try is to run 'alsactl store' before plugging headphones in with speakers outputting sound, then after unplugging run 'alsactl restore'. You can use -f switch, see the manual.

  • We are trying to package our iTunes Windows and we can't stop the auto update feature.  How can we do this?

    We have consultants here packaging many of our Apps for deployment with Windows 7.  We cannot find a way to turn off the auto update feature within iTunes for Windows.  Has someone been successful in packaging iTunes for Windows and NOT do the auto update piece?

    The Apple advice revolves around the editing the registry:

  • How do i turn off the auto lock feature?  In my options it does not have "never" on it.  It is only timed amounts.

    How do I turn off the auto lock feature.  I have only timed options.  There is not the "never" option available.

    I've got options for 2, 5, 10, 15 minutes and Never. Have you got an Exchange email account on your iPad ? 'Never' can be removed so as to protect a company's potentially sensitive email - they may not want the iPad being left/stolen with the emails on it accessible. If you remove the account the Never option will probably reappear

  • HT5295 How can I stop the auto play feature automatically playing/streaming the next podcast?

    How can I stop the auto play feature automatically playing/streaming the next podcast?

    Hi there.
    I listened to podcast there were two things I found that helped me out. Both we're in the podcast app itself.
    Firstly change the default sorting order. When looking at the list off episodes a available on your ios device tap on the description part at the top, this will bring up the settings for that podcast (subscribe mark as played etc) scroll to the Bottom and select oldest first. This will mean that if you are listening to the latest download it will stop at the end as there will be no more to play.
    Secondly, and useful if listening to older podcasts in the list, you can use the timer to stop once the current episode has ended. To do this when you are in the podcast playback screen slide the "album artwork" up, revealing the playback options and nifty tape playing animation this is where you adjust playback speed and set a timer. The timer has a number of options to set playback to stop after set amount of time. However one of these options is to stop once the current episode you are listening to ends. This can also be current chapter if the podcast you are listening to supports chapters.
    Hope this helps, if not clear let me know

  • How do you turnoff the auto correct feature in messaging?

    The auto correct feature in Messaging often changes what I'm typing to the wrong word.  How do I turn off that feature?  It is really annoying!!!
    Bill

    Hey Bill that is pretty annoying which is why I use Swift key as my keyboard. To turn off the feature,  go to settings>language and input. To the right of "Samsung keyboard" is a gear icon. Click on that.  Then click on auto replacement. Click on the on button up at the top right and it should go to off. Let me know if that works for ya.

  • How do I find the 'auto fil' feature for Firefox?

    how do I find the 'auto fil' feature for Firefox?

    Hi jasmtch,
    I am assuming you are talking about auto fill for forms and not password/logins, correct? If that is the case, just take a look at the Knowledge Base article [[Form autocomplete]]. This will give you all the information you need to use and manage the autocomplete feature.
    Hopefully this helps!

  • HT5824 I've been using numbers for iPad and I accidentally deleted a column. And the auto-save feature saved that and now I can't undo it. Does iCloud storage have backups of saved files from like 10 minutes ago? I have number

    I've been using numbers for iPad and I accidentally deleted a column. And the auto-save feature saved that and now I can't undo it. Does iCloud storage have backups of saved files from like 10 minutes ago? I have numbers synced to iCloud.
    I tried to undo it but the app crashed.
    I am hoping there's like a previously saved version of my file in iCloud somewhere. 

    No, iOS does not do short term incremental back ups to iCloud such as you get with Time Capsule.It backs up when you do soo manually, or if set properly, when the device is plugged in and connected to WiFi. It will not have saved your changes as of 10 minutes prior.

  • How to control the measure based on the related dimension.

    Hi Experts,
    In order to improve performance, I have created three kinds of time tables in DB,such as Year .Month, Day.
    Then import them into the physical layer in RPD, and combine them into one dimension in BMM.
    Actually, it has three level fact related with three time tables,so they are also dragged into one fact in BMM,and one column will be corresponding with three column derived from different Fact table in physical layer.
    So I want to know how to control the measure based on the related dimension.
    For example:
    when users drag the Year,Sales column, it will come from Year Dimension and Year Fact Table.
    when users drag the Month,Sales column, it will come from Month Dimension and Month Fact Table.
    when users drag the Day,Sales column, it will come from Day Dimension and Day Fact Table.

    Hi,
    Create a dimension Hierarchy, with Year >> Month >> Day Levels and
    Next Double click on Year Table LTS >> click on Ocntetnt Tab >> set as Year
    same way for Month LTS and Day LTS.
    So now when you select year column then server canknow which LTS to hit and Hits Year LTS.
    Mark If Helpfu/correct
    Thanks.

  • How to control the size of live data in Coherence?

    How to control the size of live data in Coherence?
    See the following statement:
    Pause times increase as the amount of live data in the heap increases. We recommend not exceeding 70% live data in your heap. This includes primary data, backup data, indexes, and application data.
    --Excerpted from http://coherence.oracle.com/display/COH35UG/Best+Practices                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

    In any Java program, it is good practice to make sure your live objects leave some room in the heap for "scratch space." Without this, you will spend too much time in GC, and, in the worst cases, run out of memory. In the general case, you can see how much live data your application requires by looking at the heap used after a full GC's. For Coherence, you should ensure that live data, as you say, is under 70% of the maximum heap size.
    Coherence provides you tools to help enforce this policy. [http://coherence.oracle.com/display/COH35UG/local-scheme] describes how to size limit your cache. By implementing an eviction policy, you can control what happens when a size limit is exceeded.
