Interfacing (DSI, CSI, I2C, etc.) • Re: Force HDMI audio with custom EDID

speaker-test reports this error:

How are you launching speaker-test? You may need to specify the output device:

BTW I already tried basic config.txt options like:

Code:

hdmi_force_hotplug=1hdmi_force_edid_audio=1hdmi_ignore_edid_audio=0hdmi_drive=2dtoverlay=vc4-kms-v3d,audio

Don't do that. The hdmi_ options in config.txt are for the deprecated firmware display driver.
The kms driver is arm/kernel based and has no knowledge of the contents of config.txt.

In general display configuration settings should be in cmdline.txt (which the kernel sees) or configured after booting.
