Team,
I have an issue my RPI4:
the TV screen is showing the content of the MP4 file via HDMI-0, but there is no audio output.
The Debian speaker-tester via sudo root gives an audio output on the TV via HDMI-0 with “Left channel”, “Right Channel” clearly audible.
I am using Debian Trixie on a RPI 4 with 2GB and the single line bash script to install the latest Anthias version.
Even using the Anthias BalenaOS version behaved the same way.
However Anthias does no play audio! It did it initially, but stopped playing Audio after the 2nd or 3rd reboot. Changing the HDMI settings and save it in the GUI did not change it.
I did suspect an unstable power supply, or heat problems, but neither a 5 Amp power supply or a RPI 4 with heat-sink and active cooler changed it. I even swapped the RPI 4 with another unit, but did not change the result!
One hint, the MP4 files to play are pretty big, some are of 10MB, some are 50 to 100MB or even larger.
I am at a loss, what I could change to get a stable Audio output via HDMI.
I just did a run-upgrade.sh to the latest version and sound came back during the upgrade still being preformed.
After finishing the upgrade and rebooting the RPI4, sound is dead AGAIN . . .
Unplugging Power on the RPI4 and plugging it in again, restored audio, but for how long it is to be seen.
I did another Reboot via the Anthias Settings UI, und Audio is dead!.
Even a Power cycle - Unplugging Power on the RPI4 and plugging it in again - did not restore audio!
Audio via Anthias is no more working, however the RPI Speaker-Test via
speaker-test -c2 -twav -l3 - produces clear sound output via HDMI on the TV.
After another round of checking, I found the anthias_viewer Log starting with the following lines:
anthias_viewer-1 | E: [pulseaudio] main.c: Daemon startup failed
anthias_viewer-1 | start_viewer: pulseaudio failed to start - video will play without audio
The Raspberry PI is setup with ALSA and not with pulseaudio.
The interesting thing is, after initial installation of Anthias, ALSA seemed to work, but after a reboot, it requires pulseaudio …
