I recently bought a Audioinjector stereo soundcard HAT to stream sound on my raspberry pi running Raspbian. I went to their website and installed the .deb installer file and ran it with audioInjector-setup.sh and then rebooted as it told me. However, it failed to boot, as it only shows a black screen, and the green LED keeps flashing steady on the rpi. Am I doing something wrong?
NOTE: I am using a Raspberry pi 3B with Raspbeian running on it.

If you have a significant hardware issue, this may stop the Pi from loading. Make sure the sound card is plugged in correctly to the Pi's GPIO header. If you plug the card in and the Pi boots (before you have run the software setup) then it is most likely that it is not a hardware issue.
For software issues, perhaps it is easier to manually setup the card, which is pretty simple.
To get this sound card to work you can edit the config.txt file by hand. Try using the nano editor to edit the config.txt file which is in the /boot directory :
nano /boot/config.txt
Comment out the dtparam=audio=on line, by putting a "#" in front like so :
#dtparam=audio=on
Make sure the Audio Injector device tree is loaded at boot time by adding this line to the config.txt file :
dtoverlay=audioinjector-wm8731-audio
Now reboot.
