Originally created by @netjiro on GitHub (Dec 8, 2016).

Hi. I'm having an issue with mumble on a fresh up to date gentoo install.

mumble loads, starts the window (empty), and spits out (console below) , then I have to kill it with ctrl+c, xkill, or kill. The window is unresponsive and I can't close it by mouse or kb.

I've tried v1.2.6 and 1.2.17, starting both as regular user and as root, same issue.
I've tried building it with as little as only alsa lib support but same issue.
Any idea on what could be wrong?
Tips on what to look for in continued investigation?

I'm running plasma 5.26, alsa kernel 4.8.12.

@mkrautz commented on GitHub (Dec 8, 2016):

Freezing the whole applications is obviously a Mumble bug, but...

The freezing is because Mumble's ALSA input thread can't read from your default ALSA device.

Do you run on a system with hardware mixing support? Do you use DMIX?
If not, my guess is that something else is using your audio device already, causing Mumble to be stuck when reading the microphone of the default device.

Are you only using ALSA on this machine. No sound server, like PulseAudio?
Are other programs able to read from the microphone when using ALSA directly, or is it just a Mumble problem?

@mkrautz commented on GitHub (Dec 8, 2016): Freezing the whole applications is obviously a Mumble bug, but... The freezing is because Mumble's ALSA input thread can't read from your default ALSA device. Do you run on a system with hardware mixing support? Do you use DMIX? If not, my guess is that something else is using your audio device already, causing Mumble to be stuck when reading the microphone of the default device. Are you only using ALSA on this machine. No sound server, like PulseAudio? Are other programs able to read from the microphone when using ALSA directly, or is it just a Mumble problem?

Thanks for the help. I'll try rebuilding with jack or pulseaudio when I'm back on Monday.
Could be that plasma hogs alsa, but I had nothing else audio related running. I have had multiple audio sources running concurrently before afaik. I'll test that as well again to make sure. I'll also test the mic, which I have not done yet on this machine.

Ok, workaround in place: force a separate usb headset as alsa card 0
Then mumble can continue to full UI, and it works ok (see later)
This does not work if the intel sound module is card 0. I'll try some more later on to see if I can get that to work...

But with the usb headset I sometimes get a stutter, precisely as reported in issue https://github.com/mumble-voip/mumble/issues/2179
so now I'm off to try to see if that can be circumvented ...

I experienced the same problem with mumble 1.3 (the 2018-07-01 git from this nix package) on NixOS (Linux 4.18.16 x86_64) with PulseAudio.

It was hanging with the same stack, same empty window, same console output before in hangs. Specifying the ALSA configuration also fixed it for me.

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Generic_1 [HD-Audio Generic], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], device 2: ALC892 Alt Analog [ALC892 Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Device [USB PnP Sound Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
$ cat /proc/asound/modules 
 0 snd_hda_intel
 1 snd_hda_intel
 2 snd_usb_audio

(This computer has an AMD CPU, so I'm not sure why I'm seeing snd_hda_intel?).

Fixed by creating this file:

$ cat ~/.asoundrc 
pcm.!default {
    type hw
    card 2
}

ctl.!default {
    type hw
    card 2
}

Audacity worked fine without this.

Does this still happen with the latest 1.3.x version of Mumble?

Mumble 1.3.3 (from nix package) now works for me on NixOS (Linux 5.9.12 x86_64), without the ~/.asoundrc workaround.

I think it has been working for a while.

Thanks for the update 👍

In that case let's assume this is fixed until someone says otherwise.
