Title:
  External laptop speakers work only for several minutes then shut off

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Linux Mint 16 Petra & Ubuntu 13.04 and 13.10
  Toshiba Satellite L655-S5150
  Running lates version of BIOS

  I can't get my laptop speakers to stay running.

  What happens is that when I first start up my laptop, sound will come out of the speakers for 2-3 minutes and then stop. If I reboot it will come back on for 2-3 minutes again. My headphones work fine for as long as I want them to play. I also tried the Auto Mute - disable idea that is mentioned in many of the posts by people with the same problem.
  One weird thing is that if I close my laptop and let it go into suspend then open it back up, the sound comes back on for 2-3 minutes. I tested the power settings on this. If I have my laptop set up to go into suspend when I close the lid (Under the “When Plugged In” settings) , the sound comes back on. If I have my power setting for “When the Lid is Closed” set to “Do Nothing” (under the “When Plugged In” settings) and close the lid, the sound does NOT come back on. Same scenario if I go onto battery power (comes back on if set to suspend). This issue seems to be tied to the suspend / power settings somehow. Just now I shut the lid and re-opend it and the sound played for 1 minutes and 27 seconds before cutting off again.

  On another note, this system is dual boot so I started up Windows and
  ran Media Player for about an hour and the sound played the entire
  time. This would rule out a true hardware fault.

  I have run the command wget http://www.alsa-project.org/alsa-info.sh
  -O alsa-info.sh && bash alsa-info.sh and saved the information
  locally. It creates a folder with sub folders so I'm not sure what I
  should upload.

  I tried installing DKMS under Mint 16 but it didn't appear to work and
  I don't have Ubuntu installed on my system any longer.

  I'm willing to try any troubleshooting steps you need to assist in
  fixing this problem. Here is some more information below.
