This is a pretty straight forward problem. I believe that Linux places your headphone jack in a state that Windows can not recognize. I have found that doing a cold shutdown (Holding power button for 10 sec.) of Linux and then booting into Windows will often fix this problem.

Skype 4.3 can only use pulseaudio sound daemon to output sound. As I understand you have no sound at all in skype so I guess you either don't have pulseaudio or you don't have it running. I would recommend you to install pavucontrol and try to figure out if you have sound input/output working. So the solution: sudo apt-get install pavucontrol; pavucontrol ...

It is not configurable from the alsamixer... when front jack is connected, works only front jack. I'm very often using toggle between headphones to speakers, in ubuntu 12.04 it works programmatically but in 14.04 can only disconnect front jack, to ...

Solved! I spent a fair few hours tinkering before I figured out that I'm an idiot, so I'll write down what I believe I did: $ gksudo gedit/yourtexteditor /etc/modprobe.d/alsa-base.conf Then, at the bottom of the text file, comment out the line that says options snd-usb-audio index=-2 Save the file, and then run $ gksudo gedit/yourtexteditor ...

How do I find out this information? You google 'x220 line-in' and find lots and lots of pages, among them the manual. So it is both line-in and line-out, but with a limitation: The combo audio jack does not support a conventional microphone

Link to a solution in Russian: Subwoofer does not work on HP ENVY dv7 It helped me activate subwoofer on Ubuntu 14.04. This might also work on other versions of Ubuntu as well. Main actions: Install alsa-tools-gui. In this package we need hdajackretask utility (maybe hda-jack-retask in earlier versions). Choose a different codec: IDT 92HD81B1X5 Under the ...

After doing some research, I found out that the problem was with me having dual boot with windows 8.1. Found the answer on this thread. As it turned out, I already had disabled Fast boot in Windows 8.1. In addition to that, I discovered I had to fully turn off from Windows and then turn on the laptop again. Restart does not work. Marking this as the answer. ...

I have found a solution for this problem. Appearantly, ALSA did not like the USB sound device that I was using. It is one of the cheap $2 ones that look like a USB stick w/headphone jack. Either way, I attached an old SB Live! PCI card I had laying around, booted up the machine and alsamixer worked with no problem. I can switch between the 2 devices and the ...

In ubuntu there is such tool as alsamixer. Check if you have that in your distro. If you do, see if below the headphones bar there is two M letters , MM. That would mean headphones are muted. pressing m unmutes them. Check if that works. Alternatively, this could be a hardware issue, in which case i'd suggest usb headphones or bluetooth

If you have sound in your guest account, then most likely you have accidentally done something wrong to the pulse audio configuration in your own account. Try removing (or renaming, just to be on the safe side) the pulse subdirectory of the .config directory of the account that has no audio: cd ~/.config mv pulse pulse-renamed Then log out of your ...

If you dual boot with Windows 8, see this answer. If headphones work, and the speaker doesn't work or works intermittently, please click "Does this bug affect you?" in the upper left of this bug. In this case, it is a bug that, in its nature, intermittently exists. I'm pretty sure it is a start-up bug of some sort, and have already noted it as such in the ...

I have a HP Envy dv7 with beats audio, probably similar sound hardware. In Ubuntu 12.04 I got it working by doing gksudo gedit /etc/modprobe.d/alsa-base.conf and adding the line options snd-hda-intel model=ref at the bottom, then save the file and reboot. Now under Ubuntu 14.04 this solution doesn't work anymore for me, but I found a solution on this ...

I have a HP Envy dv7-7390eb laptop and in Ubuntu 14.04.1 (fresh install) what worked for me was: gksudo gedit /etc/pulse/default.pa and add the following line load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe When you reboot and go into sound settings (click on volume control icon and choose ...

The alsa-driver package is outdated; the sound drivers are part of kernel, and are updated by updating the kernel package. See How to update kernel to the latest mainline version without any Distro-upgrade?

It seems there is an issue with some (legacy?) code in Blueman which deliberately unloads module-bluetooth-discover on startup (i.e. after it's been loaded from /etc/pulse/default.pa. For more details see here: https://github.com/blueman-project/blueman/issues/64.

Maybe it's too late, but have a look at my similiar question. I think, it should help. Can I configure separate sound volume for each user?

As the OP did self-answer, but not in the form of an answer, replicating answer here: Running sudo alsa force-reload solved the problem for the OP. * In similar cases, changing RUN=yes to RUN=no in /etc/default/speech-dispatcher, followed by the command above, helped. For additional details, see: http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ *)As ...
