USB Microphone not detected in some applications

I have plugged in a USB microphone and I am finding that it is not detected by some applications. When I tried the mic online at https://online-voice-recorder.com/ I was able to hear my voice. However, when I try using

arecord -f cd -d 10 test-mic.wav

and play it using

aplay test-mic.wav

I dont hear anything.

I have already edited the

/etc/pulse/default.pa

to set my USB mic as default

#### Modifications
set-default-source alsa_input.usb-C-Media_Electronics_Inc._USB_PnP_Sound_Device-00.analog-mono

Steam settings shows that the microphone used is the default one but when I try it, there is no audio.

Re: USB Microphone not detected in some applications

In general if you are using pulseaudio you should install pulseaudio-alsa (and lib32-alsa-plugins) to have ALSA only utilities like arecord be redirected back to pulse if they are using the default device. You might also be interested in installing something like pavucontrol which will show you which device is currently being recorded from, and relevantly move audio streams to the correct device of your choice.
