Surface Pro No audio to external monitor

Anonymous

Hello, I am unable to get external audio to my tv from the surface pro using a minidisplay to hdmi cable. I went into the sound options and the only two speaker options are speakers and digital audio (hdmi). The second always says not plugged in. I am connecting through a pioneer receiver to an LG tv. This works fine on my other windows 8 devices. The cable is a generic brand cable that said it has audio capability.

Actually, I found going into Device Manager and disabling and then re-enabling the "Intel(R) Display Audio" driver solved the problem for me.

Right click on the start button, and select "Device Manager."
Look for "Sound, video, and game controllers," and expand its section.
Right click on "Intel(R) Display Audio," and select "Disable."
Then right click it again, this time selecting "Enable."

This was done on the anniversary update with the latest drivers. You may have to try unplugging and then plugging back in the HDMI cable between steps 3 and 4.

This one was weird, but I was having the same problem about 5 minutes ago. Try going to control panel > sound > manage audio devices > click on your tv device and edit properties. Go to advanced then change the default format around a few times and test. The first two I tried played no sound. The third one I tried said that the device was in use by another application and asked if I wanted to stop it. I clicked yes and now I have sound.

Good Luck!

ok I did what he said here:

I was connecting to my Onkyo receiver Aux input

Went to control panel -> sound.

Properties

Advanced Tab

Clicked a bunch of different quality levels... nothing seemed to change.

Picked 16bit, 96000 hz. It said "device in use" I clicked yes.

No sound, BUT I noticed that on my Onkyo the display started changing when I played the test sound... turned out the test sound was too short, the receiver couldn't "Detect" the right format and switch to it fast enough... I got one tiny "peep" at the very end that clued me in...

So I loaded a video file with a lot of audio, and wham it detected (after about 1-2sec) and now I get audio.

I'm pretty sure I had to do the thing on the advanced tab before it started "working" because I didn't hear any "peeps" before that and I tried on other TV's (directly) and it didn't work, but in this case the delay on switching/auto detecting made the problem even more frustrating to detect (that I had fixed it!) when the test sound was too short! (maybe that's why some people on this thread said it works on the TV, but not when using a receiver! Try a long clip of something in the background.)

Thanks!

Uninstall the "Intel(R) Display Audio" driver and remember to check "Delete the driver software for this device", restart, search for driver for the device missing driver in "Device manager" (or check Windows Update).

Well, the Anniversary Update seems to have brought an interesting twist to the problem, and a possible solution. (I know, I'll probably regret this optimism later). Now when I connect a TV, say, to my SP4, I do get the audio device listed and automatically selected - every time. (The AU update even makes this easier to check - just click on the speaker icon.) However, every app that I try fails to play any audio (WMP, Movie & TV, Groove, Edge etc.) and claims that the audio device is in use by another application, and system sounds keep coming through the internal speakers despite them not being the default device. So, I did this:
- Connect the external display.
- Bring up the audio device property page for the speakers. (There should be a speaker device now, even if it doesn't work.)
- In the Advanced tab, uncheck the option to allow applications to use the device in exclusive mode.
- Apply settings end disconnect the cable.
- Reconnect the display cable - bam it works!
Now, there shouldn't be any application trying to hog the speaker device as soon as I plug it in, so something is clearly still wrong after all these years and generations of Surfaces. Obviously, if you try to use an application that requires exclusive access to the audio device, it will not work that great with this fix. Hello Microsoft, are you looking into this?
