Ubuntu sound volume is 40% lower than in Windows

12.04 sound alsa soundcard volume-control

1,316

Solution 1

Open a terminal and try this command:

alsamixer

This will open the ALSA mixer application, which should allow you to be able to increase the level of master volume sound.

Solution 2

I don't know if this will help you, but on my system (a Thinkpad T510) I have to open up the sound control panel (right-click on the sound icon in the notification panel and select "Sound settings...") and move the volume bar to 140% (or so, it doesn't actually change the displayed number) to get full volume. I don't know why this is and it's quite irritating since the volume keys on the laptop will only go up to 100% and I have to open the control panel several times a day to be able to hear anything. Just like in your case, this is not a problem with Windows where 100% really does mean 100% of the available hardware volume.

My question will probably sounds dumb to most of you but I have been struggling to find out the problem. I basically have a method and a view (created by right click-> Add View).

This is my method:
```
public ActionResult yearlyOverview(FormCollection values)
{
    return View();
}
```
And this is my view:
```
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    yearlyOverview
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">    
    <h2>yearlyOverview</h2>
</asp:Content>
```
The error message that I get comes from the browser:

Sys.ArgumentException: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON. Parameter name: data

This is the master page code:
```
    <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>

Has anybody already stumbled on this problem?

  Nothing wrong with view - you need to investigate more and update question. This error have nothing to adding new view, but rather what you render in your view... Seem to be an issue with some "data" object not properly created, possibly this information is needed by master page portion of the view.

  @AlexeiLevenkov - you can have Page directives in an ASP.NET MVC view? Or is it only valid if you are using the WebForms view engine? Razor would not understand those, right?

  @KarlAnderson Razor will not understand those page directives.

  Post your master page code.

  when you added a view using right clik, what option you selected for : View Data Class ?

  When I added the view I selected ASPX (C#) as view Engine

  I wonder how your question has been up-voted. You are mixing asp.net mvc with classic asp.net.

  @KarlAnderson - with Razor you can get into similar issue ("some random requirements coming from master view") when your "_layout" page introduces requirements (like adding some script that requires particular object to be rendered by page's code).

Yes I also did that a few times, but as you said, as soon as i use the keyboard to change the volume that gets reset. But, having the slider on "Sound settings" to the max (>100%) gives me still much lower volume than in Windows.
