Raspberry Pi4 model B 3.5 mm audio / HDMI issue
Posted: Fri Jun 23, 2023 10:46 pm
Hello Everyone,
After the "OMAP3 not supported" notice, I switched to Raspberry Pi4 B.
There is another issue with it. There is no audio output signal nor on the second HDMI port neither on 3.5 mm jack.
I read RiscOS Wiki article about it and it declares that this is a problem of RISCOS driver.
However the JASPP games and ADFFS start fine when display is plugged into HDMI2. Unfortunately there is no sound of any kind on any port.
Which is sad.
When I switch to the HDMI1 (closest to USB-C connector.) The system generates sound normally
but starting games with ADFFS brings it to the black screen. (The game starts - I can hear the sounds from it)
In simple words - I can see the game running but can't hear it running or vice versa.
It only depends on what port the display is connected to.
My CMDLINE/TXT contains:
disable gamma
disable_mode_changes
and CONFIG/TXT:
fake_vsync_isr=1
disable_overscan=1
hdmi_ignore_edid_audio=1
audio_pwm_mode=2
What is the difference for ADFFS if the system uses HDMI1 or HDMI2 port?
(monitor is the same, MDF is the same, no changes in config files)
Completely OT:
On RaspberryPi OS 3.5 mm audio output always works fine with any HDMI port.
Maybe I am wrong saying that but to me it sounds like there must be a configuration flag of some kind to enable 3.5mm output
no matter what HDMI port is in use.
