Staticy sound when Mumble Starts, PulseAudio

Hey guys! I've noticed that when I start mumble that all my sound has static and sounds bad.  It sometimes goes away if I stop everything from making any sound for a few minutes. I'm using Pulseaudio. I've never had any issues like this before, so I'm unsure of what else I should include in my post.

If anyone can help lead me in the right direction of how to solve this or even what may be causing this, that would be extremely helpful.

Thanks,

Re: Staticy sound when Mumble Starts, PulseAudio

Post 

sudo fuser -v /dev/snd/*
pacmd list-cards
pacmd list-sinks
pacmd list-sink-inputs

once before starting and once after starting mumble and reproducing the issue. Any configuration changes we might want to know about on pulse or ALSA's side?

What also might help is having a 

journalctl -f --user-unit=pulseaudio

during that whole procedure running and pasting any output that might occur.

Re: Staticy sound when Mumble Starts, PulseAudio

I do not remember if I have made changes to my configurations to pulse or alsa. So here are my pulse and alsa config file.

/etc/asound.conf

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

Re: Staticy sound when Mumble Starts, PulseAudio

Sorry for thhe late response.

You have the echo-canceler hanging in between there. Without any further configuration done to it, it just takes some suboptimal defaults which seem to lead to that static you hear. Can you get that out of the equation (comment the last line in default.pa) Restart pulse or  

pacmd unload-module echo-cancel

and see if that fixes it.
