Pi5 audio oddities

A Pi5 running bookworm has suddenly lost sound. The last update was a couple days ago and seemed unrelated to sound in any way.

Right now audio output is via "Digital Stereo (HDMI) Output". There's no sound from YouTube or the New York Times and I still hear a burp when I power cycle the speaker system, so the analog side is alive. There's also a small chirp when I power-cycle the HDMI monitor, so I think the HDMI-audio splitter in the display is alive.

Right clicking and holding on the speaker icon at the upper right of the screen displays HDMI and Device Profiles, but both seem greyed out.

Anybody seen this sort of mischief?

Thanks for reading!

Not on a Pi 5, but I've had a Pi 4 which once or twice lost sound if it was rebooted remotely when the TV it was connected to was off, even though the /boot/config.txt file told it to always use HDMI audio. The only thing that worked was to reboot with the TV on.

I too have had trouble with a Pi4 losing sound but up to now I've blamed it on the HDMI monitor, since power cycling the monitor brought back the sound. Tried that in the present instance with the Pi5 but it didn't help.

Next I tried a warm reboot, but the machine got stuck with a black screen, though I think it was coming up to multi-user. It would answer a ping and refuse an ssh connection, per the configuration.

Eventually I did a power cycle and played with audio under rapsi- config, now sound works and at least a couple of warm reboots were successful as well. At the moment, a Chromium browser tab is stuck and won't scroll, but four other tabs behave normally.

I guess maybe it's just Bookworm/Wayland being buggy.

Thanks for writing,
