How's your CPU usage when running Mumble?

[mw-ces]

@davidebeatrici round 10% and mumble itself round 1% or less

You are using bluetooth headset probably. Windows audio forces 8kHz (mono) instead of 44.1kHz+ (stereo) for bluetooth audio when using microphone together to split the bandwidth.

Use wired headset or other microphone.

omg, what's wrong with you windows, come on! Can I do anything else in the settings or whatever, i don't want to go back to wired headphones :')

Use another microphone. You may use laptop built-in mic or anything else. When you look into Windows Sound settings, Playback tab, be sure to select proper output device. There will be two related to your headset. Each represents different mode, one high quality, output only and the other allows microphone input with low quality output. If you disable the low quality one, you will always hear good sound but microphone won't work. You might also have to disable the headset microphone depending on the implementation of some bluetooth stuff.
I'm talking about this tab:

@mw-ces @Krzmbrzl please change the tags as it is not a mumble bug

I knew about the forced mono behavior, but not about the huge bandwidth restriction. Insane.

@mw-ces Just to make sure that it is a Windows issue: try to record something using an application other than Mumble (e.g. Voice Recorder) while listening to music.
