Win 7 x64, latest snapshot. Playing Left 4 dead 2 working perfectly. Switch to another game - and my mic starts getting triggered by other people in mumble. Change audio output settings by moving slider 'other applications' from 39 to 40%, pressing apply and closing the window. Now the leakage stops. Does mumble do something in the background without showing it in the settings GUI when you launch different apps?

    Mumble does nothing audio wise if you enter a game. If you suddenly experience loopback it is most probably a driver issue or something the game did.

    Today it happened again with the latest snapshot (http://mumble.info/snapshot/mumble-2009-12-28-0243-86f851.exe). I had set Attenuate applications when other people speak to 40%. Start mumble and everything works. Start Left 4 Dead. Still works. Exit left 4 Dead. Works. Start Left 4 Dead again - my friends start triggering my mic. Exit Left 4 Dead Attenuate applications is now at 39%(!) Change it to 40. Works again. What gives?

     
  • Mumble doesn't touch recording settings at all, the only thing it touches is application output volume. Are you using PTT or VAD for transmission?

    All of us use VAD, and the people seeing the problem seems to be clients using Windows XP. Now I haven't played Left 4 Dead in a while, and Team Fortress 2 taht we usually play doesn't seem to have this problem.

     
  • This sounds more like a max-amp problem; try reducing the maximum amp, and you should stop triggering on other people. This assumes the problem is that your mic picks up your headset; if it's actually sent there by the OS, it's a driver problem and not something we can work around in Mumble.

    If it was a max amp problem, why does it go away when you change the attenuate value and set it right back? This happens irregularly for me on W7 and my friends on XP and Vista. Usually when we've been playing a steam game for a while.

    Happened again yesterday when playing TF2. A small change in attenuate - apply and then re-set the value - apply fixes it.

     
  • Sorry about the long delay getting back to you.

    It goes away when you change any setting, since that resets all amplification :) That being said, please try current snapshots, as gain has had a few adjustments to it.

    Ok good to know. I've started using 1.2.3 snapshots now, so I'll see if the problems go away over the next weeks. I'll keep you posted if the problem appears again.

    It's still happening. Tonight we played TF2 and suddenly I started to trigger by another player. The triggering player running 1,2.2 and I running the latest snapshot (7208fc) Problem went away when I did a change in audio output settings and pressed apply,

    Today it happened during playing Alien Swarm with a friend. My mic got triggered somewhere in the middle of the game, without either of us altering anything in mumble. Both using Voice activation. Me on 7208fc and him on 1.2.2. final. Server is running 1.2.2 final.

    This is so frustrating - it happened again yesterday when playing Left 4 Dead 2. Reset audio processor doesn't help, but changing attenuation a notch and bringing it back again with an apply presssed in between solves it.

    This is with the latest snapshot of mumble on our 1.2.2 server. DxDiag data still valid. The other clients connected is a mix of 1.2.2 and the latest snapshot.

    The only upside is that since mumble now has full window overlay support I can fix the problem from within the game. It would be nice if 'reset audio processor' fixed this so that you could bind it to a shortcut.

    Changed the title. It happens spontaneously, and not when changing the game. We have turned positional audio off.

    This happens during gameplay every Friday when we hook up for gaming. It's usually my mic that starts triggering by the others after a while, but other people can cause it too, so it's not just my Creative audio card.

    Last Friday I forced everyone to use the latest snapshot of the client to rule out any 1.2.2/1.2.3 inconsistencies, but the problem still occurred. This day it was either me or one of my friends that got triggered by the others with horrible echo as the result.

    It would be nice to hear if you are able to reproduce this or if we're gonna abort the transition to 1.2.3 and stick to 1.2.2 where this works.

    It's not feasible to have to open up the overlay, slide the attenuate slider back and forth several times during gameplay.

    I could try to run the 1.2.3 server snapshot if you think it has any role in this.

    I'm not able to reproduce this :-( Neither on my xonar nor on internal realtek.

    Looking at what we do with audio in Mumble I cannot really see a way in which Mumble could do this on its own. Sounds like the other application is messing with the device or the driver itself does something strange (I guess you updated that one already).

    Are you sure this is connected to a game or another app running? Because another possibility might be the AGC somehow letting amplification run away and crosstalk causing the VAD to trigger. This would also explain why messing with the config menu fixes it (applying settings there resets our processing pipeline). Is you mic more sensitive in general when the issue occurs and does speaking for a bit resolve it?

    It is entirely possible that wire crosstalk on your headset feeds back the output to the microphone line. I've seen that several times when people were using front audio connectors of onboard sound, but it should also "work" for any shoddy headset cable.

    Try reducing your input amplification as far as possible, that could help pushing the crosstalk down. Try playing with echo cancellation too. All in all though, I suspect it is an artifact of your cabling and the only proper solution would be replacing that.

    Quick follow-up:

    Play REALLY LOUD STUFF through the same output you're using for Mumble make sure the microphone is active and that it's otherwise quiet in the room, and open the Audio Statistics dialog (menu Self→Audio Statistics). If you notice an influence of the stuff you're playing on the spectrum display or in the speech detection meter, you're either mixing output signal into the recording source somehow, or suffering from crosstalk.

    Your dxdiag also shows that you seem to be using Line2+Mic2 as default input. If you're using that for Mumble, try the microphone-only port instead. It's possible that the signal path on the "mixed" port is too ghetto.

    Thanks for the troubleshooting tips.

    I'll try them out tonight. I'm using a Creative X-Fi Fatal1ty with front connectors, and will be a bit disappointed if they turn out to be the culprit. I haven't seen this problem using mumble until the 1.2.3 snapshots with exactly the same cabling/physical setup. The headset is a Creative HS-900.

    My friend who usually also has this kind of trouble does not have the same audio card nor a front connector setup however.

    I did a thorough analysis of my mic setup. I'm able to play spotify at full volume without mumble reacting.

    When playing left 4 dead 2 today my mic got triggered anyway after about an hour into the game - no settings changed EXCEPT that I opened the in-game overlay once without changing any sound settings.

    Could you check whether the VoIP features provided by l4d2 and tf2 themselves are switched off? If they aren't does switching them off change anything?

    In-game voice was on in both L4d2 and TF2 (PTT). I'll disable them for the upcoming gaming session on friday and see if there is any change.

    We use Voice activation in mumble.

    Any update on this?
    Were you able to fix it?

    What do you mean by “I opened the in-game overlay”.

    Are you using the 1.2.4 RC?
