Users can hear me, but I can't hear them [debian] #2007

Closed chrismp closed 8 years ago

chrismp commented 8 years ago

My OS: Debian 8.2 (Jessie) My desktop manager: MATE

I can listen to audio/video files, hear sound on YouTube and other sources.

I ran sudo apt-get install mumble and went through the audio setup wizard. I could hear myself during the setup.

Once setup, I opened MATE terminal. I ran mumble mumble://MyUserName@someserver.mumbleboxes.com:PORT_NUMBER_HERE to connect to a friend's server.

They could hear me, but I couldn't hear them. In the "Configuration" menu, I went thru each audio output device, but nothing worked. In fact, when a friend spoke, the mouth icon next to their username did not turn red to indicate they were speaking.

How do I fix this?

I have the same issue for a few days now, and am on jessie as well. It worked fine ~ a week ago and I didn't change anything in my mumble settings. People can still hear me but I can't hear them I tried

My guess would be that this is related to the recent kernel update to 3.16.7-ckt20-1+deb8u1. This is the only "big" update that I remember and might be related. @chrismp which kernel are you using? (uname -a)

hacst commented 8 years ago

Try if forcing TCP (With advanced checked go to Network -> Force TCP Mode) helps. If so this is likely caused by a Qt bug which randomly prevents us from receiving UDP.

Once https://github.com/mumble-voip/mumble/issues/1968 is resolved we should at least get automatic fallback to TCP if this issue occurs.

@MagiX13 3.16.7-ckt20-1+deb8u1

@hacst That worked

chrismp commented 8 years ago

@hacst Is there a way to start Mumble with the box checked? So I don't have to go to the sub-menu and check it each time I start it up?

hacst commented 8 years ago

Hm. That setting should be stored like any other setting.

sharkwouter commented 8 years ago

@hacst I've been having the exact problem and have tried the same troubleshooting steps @MagiX13 used. I also use Debian Jessie and I stopped being able to hear people at about the time this issue was created. I use the Gnome desktop (version 3.14).

I've found out that I can only hear people who transfer no more that 72 kb/s. If people put down their quality settings I can hear them. Changing the maximum transfer on the server does not fix this and other users can hear each other (they are on Windows). I can hear myself with high transfer with server loopback.

If I check transfer from a person which I can't hear, I see transfer happening, but the lips don't light up.

It might have something to do with a kernel update, since https://www.debian.org/security/2015/dsa-3426 but I can't test the older kernel anymore, because I don't have the linux headers for it anymore (which means no xorg for me).

I posted on the forum as well: http://forums.mumble.info/viewtopic.php?f=4&t=2878#p7684

I haven't tested using TCP yet, will try that, but even if it works that is not a real solution to this problem.

I hope this helps.

I have this on Debian Stretch. After some time (1 to 15 minutes) I stop hearing people.

mumble 1.2.18-1 Linux 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux

@philip-bl Try 894ade2, available via adding the PPA at https://launchpad.net/~mumble/+archive/ubuntu/snapshot to your sources.list and using apt-get source --build This fixed the issue for me.
