  • 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,
