'No sound output on Raspbian 4.4.210, Raspberry Pi 4

The sound has stopped working completely on my Raspberry Pi 4. It's plugged into HDMI 0 into a TV. I've checked that the TV still plays sound. The sound will work with bluetooth devices only, but will not play through both HDMI 0 and the aux jack. The way I've been testing if the sound works is by using YouTube on Chromium and RetroPi.

As far as troubleshooting goes, I've went into config.txt and tried changing hmdi_group and hdmi_mode, and reinstalling the alsamixer and alsa-utils.

Ive also tried:

sudo amixer -c 0 cset numid=3 <n>

However when I tried:

cd /opt/vc/src/hello_pi
 make -C libs/ilclient
 make -C libs/vgfont
cd hello_audio
 make
 ./hello_audio.bin

This did work.

If anyone could help me with troubleshooting it would be very appreciated

  1. Make your speakers are unmuted, and cranked to full. You may have to put your ear up to the speaker, as it may be very soft.

  2. Try this: https://www.raspberrypi.org/forums/viewtopic.php?t=5062

Comment if this does not work.

Try this:

sudo apt-get install alsa-utils
sudo modprobe snd_bcm2835
sudo aplay /usr/share/sounds/alsa/Front_Center.wav

I had the exact same issue. An update fixed it for me.

sudo apt update
sudo apt upgrade

For me I found that Raspbian had switched from using hdmi to the jack for sound. This happened after I'd installed Synaptic Package Manager. You just right click the icon in the top right of the screen and select whatever you want.
