Additional context

• audio is working over headphone jack from the terminal by typing: /opt/vc/src/hello_pi/hello_audio/hello_audio.bin

• Audio device settings:

  • sound card: bcm2835 ALSA (only this entry is visible)
  • PCM sound bar is set to maximum

• Pulseaudio

  • package removed, purged, reboot and reinstalled: same issue
  • output devices: set to Analogue out (100%) - HDMI is NOT in the dropdown menu
  • configuration: internal audio > set to: Mono Analogue Out. No HDMI

VLC:

• playing either a video or audio: no sound
• Pulseaudio shows an audio bar moving while playing sound and this bar is almost at its maximum.

Chromium

• playing video: same issue

[andrewpmiller]

@jdescelliers I had the same symptoms that you reported (at the time, my firmware version details were 4.19.86-v7l+ #1283). I updated the firmware a few days ago (4.19.88-v7l+ #1284) and the audio is back.

When I first saw your issue, I ran dmesg and noticed a number of warnings about bcm modules that were loading from a staging directory and wondered if that was related to the loss of audio... but those warnings still appear in the output... so 🤷‍♂️

YMMV but it might be worth updating the firmware to see if your audio returns.

[JamesH65]

Been a few changes in the audio area - can people seeing the issue please update to the latest firmware/Raspbian, retest, and if ok please close the issue.
