              Use your android phone as a karaoke microphone in Linux.md
            
          
    micclient+WoMic is close source, while Mumble is open source,
so on armbian tv, I can only use Mumble+Murmurd+Plumble.
===================="mumble+murmurd"(on arm64 armbian linux tv)+plumble(on android/ios)====================
refer: https://github.com/diyism/mic_over_mumble
sudo apt install mumble mumble-server
sudo systemctl stop mumble-server.service
sudo /lib/systemd/systemd-sysv-install disable mumble-server
wget https://github.com/pzmarzly/mic_over_mumble/raw/master/mic_over_mumble
chmod 744 mic_over_mumble
./mic_over_mumble
#config echo cancellation
#config minimal delay 20ms
#next next and exit and murmurd server started
#muble client started, input a random user name
#install plumble free version on your phone
#start plumble and cancel certification generation
#input a random user name that is different to the mumble client user name on armbian tv
#now you can sing to your phone, and your voice will be played on the armbian tv immediately
===================="micclient-x86_64.AppImage"(on amd64 linux pc)+Wo Mic(on android)====================
If your linux release is using pavucontrol(pulseaudio), you should do:
$ pulseaudio -k
$ killall micclient-x86_64.AppImage
$ sudo modprobe -r snd-aloop
$ sudo vi /etc/pulse/default.pa

add into default.pa:
load-module module-alsa-source device=hw:CARD=Loopback,DEV=1,SUBDEV=0

$ sudo modprobe snd-aloop
$ pulseaudio --start
$ wget https://wolicheng.com/womic/softwares/micclient-x86_64.AppImage
$ sudo chmod 777 /usr/bin/MicClient
$ sudo mv micclient-x86_64.AppImage /usr/bin/MicClient
$ while true; do nohup MicClient -t Wifi 192.168.1.100 > /dev/null 2>&1; sleep 1; done &

192.168.1.100 is my phone IP in local network, you should change it to your phone's LAN ip.
In pavucontrol(Volume Control), in "Input Devices" tab, enable "Built-in Audio"(not "Built-in Audio Analog Stereo") as input device.
And redirect MicClient audio to virtual output device, first in "pavucontrol/Input Devices" to tick "Built-in Audio" to "Set as fallback" and then:
$ pactl load-module module-loopback latency_msec=1

Now with WoMic in android and micclient-x86_64.AppImage in x64 linux, you have a set of home karaoke equipment with near 0 latency.
If you hear many noises, you could try to switch the "WO Mic Settings/Audio source" in your android phone, for example: nexus 6p should choose "Mic(mode 2)".
To disable redirecting MicCleint audio to Output Device:
$ pactl unload-module module-loopback
