c media usb audio device microphone not working

I placed a VOIP call using Google hangouts from my computer to my phone and I could hear audio from my phone and I could hear my voice coming out of my phone when I spoke into the headset microphone. I went back into the sound settings and again was able to hear audio through my headset and found that sound was now being picked up from my headset microphone.

However the microphone did not appear to be picking up any sound.Īfter troubleshooting, I unplugged the USB-AUDIO from my new hub and plugged it directly into a USB port on my computer.

Windows sound settings show the USB-AUDIO device and I was able to hear stereo sound through my headset. I connected my headset’s headphone and microphone connectors to the USB-AUDIO device which I then plugged into my new hub. The “PCM device” is the argument we’ll need to provide to aplay, telling it which audio interface to use.I just purchased a USB-AUDIO device and a USB3-HUB7C and they do not appear to play well with each other. Now let’s see how this works (note that this guide is for the current – November 2017 – version of Raspian Stretch Lite, but it should also work with Raspian Stretch Desktop). This may be necessary in some circumstances, but often it’s not: Insteads simply specify the desired output each time a command to play some audio is run, and boom – we don’t have to care about the defaults at all. You’ll find a lot of posts about this, most being targeted at older versions of Raspian and/or incomplete in other ways.Īlso, all these tutorials talk about changing the Pi’s default audio output. But how do we make the Pi use the external interface instead of its own audio output? So we decided to use an external USB audio interface instead. The Pi features an onboard audio output, but its quality is rather poor. The Raspberry Pi powering our status screen is also connected to our office doorbell: Everytime someone rings the bell, the Pi plays a short audio file.
