8.2.5 -> 8.3.2: lost audio device

[Tim Curtis]

The log entries below indicate a problem with the file /boot/config.txt

Code:

20230426 152622 worker: WARNING: Boot config restored
20230426 152622 worker: WARNING: Restart required

The /boot/config.txt file looks like below on a fresh image.

Code:

pi@sig:~ $ cat /boot/config.txt
[cm4]
otg_mode=1

[pi4]
hdmi_force_hotplug:0=1
hdmi_force_hotplug:1=1

[all]
disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
hdmi_force_edid_audio=1
hdmi_force_hotplug=1
hdmi_group=0
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=on
#dtoverlay=disable-wifi
#dtoverlay=disable-bt

If yours is empty or otherwise looks corrupted then edit it and replace the contents with the above, then reboot.

Code:

sudo nano /boot/config.txt

Ctrl-x y to save

sudo reboot

You will prolly need to reset Audio Config to HDMI 1, reboot and then set it to your preferred audio device.
