[SOLVED] "Output is set to HDMI but no audio device was detected on the HDMI port."

[rph-r]

Hi,

I have no more sound after no particular action, shutdown and reboot. In the settings "output" selector I have only HDMI and 7 lines named "empty".
I updated the system, but it doesn't work better.
Here is the /boot/firmware/config.txt

Code:

It is said in another post it was solved by doing:

Changed Settings > System > Startup Options > Integrated audio from Kernel mode (default) to Firmware mode (Legacy).

but I don't have this option.

[Tim Curtis]

Reboot and then post the contents of the startup log.

The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from any of the Config screens. The startup log will be at the end of System info output.

here is the log:

btw, I'm using an Audiophonic I2C device, and it was working perfectly until today...

[Tim Curtis]

The symptom "it was working perfectly until today..." suggests something external to moOde software.

[TheOldPresbyope]

@rph-r

Hmmm. Your log includes the entry

Code:

20250316 010815 worker: Cards:  0:vc4hdmi         1:empty           2:empty           3:empty          
20250316 010815 worker:         4:empty           5:empty           6:empty           7:empty

e.g., only the HDMI interface is detected as an audio device.

Here's the same entry from one of my players with a USB Creative Tech BT-W2 adapter which presents as an audio device,

Code:

20250314 150313 worker: Cards:  0:W2              1:vc4hdmi0        2:vc4hdmi1        3:empty           
20250314 150313 worker:         4:empty           5:empty           6:empty           7:empty

This happens to be an RPi 5B so two HDMI interfaces are found in addition to the Creative Tech USB audio device.


To address Tim's point, how about you also run the following command from the terminal of your player

Code:

lsusb

Here's what I get from mine, showing the Creative Tech USB adapter is detected.

Code:

As I said it is connected with I2C. I hope it helps...

@rph-r

Sorry. I had a mental lapse there   

I assume you mean an Audiophonics I2S device. Has a "Named I2S device" (or its DT overlay) been selected and loaded? The OS, and hence moOde, will not know of the presence of the device until this is done.

Regards,
Kent

[rph-r]

Sorry. I had a mental lapse there   
I assume you mean an Audiophonics I2S device.

Same here, it is I2S indeed.
It was selected (ES9038). I selected another and reselected it, rebooted, and it is working now!
Since I already had trouble with the loss of device config due to empty config.txt I haven't thought to tweak in this config.
https://moodeaudio.org/forum/showthread.php?tid=2303
But I really don't know why the config changed.
Thank you for your help!!
