Question have to run alsamixer to unmute sound after reboot


sound on laptop running linux mint 9 isadora after restarting or if computer is idle. when the computer is idle for a while the sound will stop working even though it doesn't show muted. after restarting i have to run alsamixer and the master tab will be muted. i can unmute and it will work until the computer sits idle for a while. any suggestions.

bash: /etc/pulse/default.pa: Permission denied
any suggestions? I'm very new to linux so I'm not sure i did it correct. I went into terminal and entered /etc/pulse/default.pa at the $ prompt. was that right?

I'm not running Ubuntu right now, but I'll try to guide you in simple steps.

You're not supposed to run the file, you need to edit its content.

Launch a shell prompt and in it type: sudo gedit /etc/pulse/default.pa

Assuming the file exists, you should see the contents of the file in gedit (a file editor similar to notepad).

Locate the relevant line and put a hash (#) in front of it.

Save the file and exit.

Try restarting your computer and see if it resolves the issue.

When you say
Quote:
ran sudo gedit /etc/pulse/default.pa
I assume you mean "ran the command and edited the file". Just opening it up isn't enough

While this doesn't "solve" the problem in the proper sense, adding
Code:
amixer sset Master unmute
to your .bash_profile should fix the problem as well

After the computer was idle throughout the night - had to restart to have sound. sound does work without having to unmute in alsamixer on restart. any suggestions? By the way, the laptop lid was closed, so the computer was suspended. Does that matter?

Well, the easiest "fix" I can think of is to create a launcher to run the command I gave, so unmuting the sound only takes a click... But like I said before, it's not really a solution - perhaps the problem will be fixed in an update, or perhaps you'll work out what it's upset about Maybe searching through /var/log to see if there are any relevant messages.

Anyway, to add a launcher:
Right-click on a panel (if you don't know, this is the GNOME equivalent of the Windows 'taskbar'. It's at the bottom/top/side of the screen )
Choose "Add to Panel"
Choose "Custom Application Launcher"
Click "Add"
Click on the icon of a spring and find a nice volume-related icon - "/usr/share/icons" has lots, I picked "/usr/share/icons/hicolor/scalable/multimedia-volume-control.svg", but this might not be on your system.
Enter Name: "Unmute volume"
Enter Command: "amixer sset Master unmute"
Optionally, enter a comment.

If you click on this launcher it should unmute your volume
