No sound at all.

Technical Support
Hi all,
I've gone through about 80 threads on here about how to fix this problem but none of the quick fixes seem to work for me. Switched to 5.1 sound, stereo, mono, and all options in between but I am still getting no sound (from any program at all) while Starcraft is running. I'm running Windows 7 and went to the HP website to make sure I was running the most up to date driver. I've gone through the speaker and audio setting in Windows to make sure they were set to 5.1, and then to stereo, restarting the game each time to try to match up the setting but to no avail. Any help would be much appreciated :D
I have almost same problem.

Before my output device was at default and by changing it I was able to hear the game sound.

Although, I still can't hear any other sounds from other programs.
I have read most of the threads on the subject and I can't find anything neither.
I Have the same problem i just had it happen to me tonight.
I was listen through headphones when I alt tabed out of SC2 and unpluged my headphones in the process, when I alttabed back into game i have no sound
Its driving me crazy
Ive spent two hours now reading everythread aviable on the subject and trying all the fixes none have worked for me also
Ive gone through and reset everything back to default and when i say eveything i mean everything from ingame options to my computer audio options
I checked all the things Hongkai said
Tonight im going to reinstall if this doesnt fix it I dont know wat to do
SC2 is near unplayable without sound as a RTS for me
Some Support soon is needed should I provide me dxdiag? ill list it hear and check back in the morning :_(

Someone plz help me!
I found something interesting today. When I am on a skype conversation before playing stacraft 2, all the audio set up work beautifully.

Somehow this resets everything to default and i can hear all the music from starcraft and any other music at the same time.

At least we have that!
I figured out what the problem was. In the control panel under Hardware and Sound, head into that specific device's information (the headphones/speakers). In here, under the Advanced tab, there's an option to "Allow programs to take exclusive control of this device"

Disable this checkbox and you're good to go! <3
I've tried all of the sound options and I changed the control panel option as well. My audio works with everything except when the game is launched. Please help?
did not help at all
I just had the same problem. Was running Ventrilo and have my hotkey set to left ctrl. I think the disable sound command is ctrl+s or something. I went into the sound options and the enable sound box was unchecked; enabled sound again and it works. Give it a !@#$.
WAAaaaaahh!!!... WAaaaaah~ no soooooouuuund~~~ help me~~
click sound thing by clock on bottom right, see the name of the driver its running on. for me it looked like headphones, then just match it it with the one in the game settings. this worked for me atleast.
I found a fix for mine, a wierd one.

Control panel>
Communications tab >
"when windows detects a communication activity"
check the "do nothing" box.

The solution from the starcraft II support page worked for me. In starcraft go to Options,Sound, under Setup use the dropdown to select your output device. It was on Defaut instead of my headphones. I got the no sound issue when I connected my laptop by HDMI to my TV to watch a movie and then play D3. I had also right clicked on the sound icon in the Taskbar to check that my headphone were set to default.
I had the same problem and after reading all the forums whit no resoult ... i pusht CTRL + S and everything works perfecly. CTRL + S work in the menu too, you dont have to be in a game to use the shortcut.
I hope it works for you too
I have been trying to restore my volume on StarCraft2 I just bought the game and beat it two days ago. Ever since I beat the game there is no sound at all. I even re-installed the game, played with the volume on both my computer and the game's sounds settings..nothing, no help online nothing from Blizzard. Any 1 have any idea how I can fix this?
YEAR 2017!

When you were working with your with your computer's volume, did you open the volume mixer to check Starcraft II's individual volume? It's possible to mute the game in the mixer which is what I tend to see when most things in this thread don't work.

    1. Open Starcraft II and alt-tab back to the desktop.
    2. Right click the Sound icon on your computer's task bar and choose Open Volume Mixer
    3. Scroll over to the Starcraft II option in the mixer. Make sure that the Mute button isn't clicked, and that the sound is turned up in the mixer.

There are also hotkeys to mute the game and mute music. If you go back to the game and press Control+S does the sound come back? How about Control+M for the music?
