I have two audio devices in my machine. The internal onboard Realtek (optical out -> surround setup) + Line6 UX1, external usb (for guitar inputs/amp sim).
I switch between them as needed. The flash player does this too, but always when I don't need it to.
Example. A youtube video finishes. The sound came from the speakers, as it should. I click the next one. It starts playing but there's no sound - except from the headphones connected to the UX1. This happens once or twice a day.
Does anyone know what's going on?
Chrome, Win7 64bit.
I haven't seen this one come up before. I've got 3 different active playback devices in my system, but Flash Player (and all my other apps) output to the default device as long as they were started after the default device was changed. How are you changing your audio playback devices?
I just right click the speaker icon->playback devices->select device, make default.
When this happens the the correct device is btw still with the green check icon in the Playback Devices->Sound dialog. How I used to fix this was by opening that dialog, make the other device active (the one I don't want, the one flash decided to play through) and then change it back to the correct one again. Then the sound kicks in. I found a better way to fix this today though. One or two browser refreshes does the trick. Usually just one.
I also have a third device that shows up in the Sound dialog, the realtek analog out, but it never switches to that. I also never use that one.
sometimes I switch between interfaces while audio is playing - could that be confusing flash?
also fyi I almost always have multiple tabs open in chrome with flash running in them. a bunch of youtube videos on pause is not uncommon.
I don't know what more we can do other than to enter a bug at bugbase.adobe.com and have someone take a look. I suspect switching interfaces while Flash is in use will be unsupported. In the bug report, it'll be good to note if this is new behavior (ie. it started behaiving like this in 11.3, but 11.2 and older were fine). However, the key to getting this fixed will be to get other users running into the same problem to vote for the bug.
You might also want to play around with third party mixers, like http://www.actualsolution.com/power_mixer/
nevermind. I do not want to try third party stuff. not acceptable solution.
ignore my previous thoughts about the cause of this - it is completely random.
happens all the time. firefox, chrome, steam client.
I disabled the device flash keeps switching to (line6). It was at the top of the Playback Devices->Sound dialog. It is now gone but flash still keeps switching to it - completely killing the audio obviously.
