Description:
When a TV or other monitor that uses hdmi audio signal is connected to an RPi no sound will play through the speakers.

Additional info:
* package version(s)
alsa-lib 1.2.6.1-1
* config and/or log files etc.
* link to upstream bug report, if any
https://forums.raspberrypi.com/viewtopic.php?p=1979825#p1979542

Steps to reproduce:
Boot RPi with HDMI audio/video connected and try to play audio:
aplay -D default:CARD=vc4hdmi /usr/share/sounds/alsa/Front_Center.wav
No audio will play

When the attached config file from the link is substituted, the RPi will play the audio sample. It can also be used as an audio output for mpd, for example, and the sound will play through the connected hdmi audio output.
