I own a Raspberry Pi4 8gb - I changed the original case (white and red with miniHDMI ports) with the Argon one Pi4 V2 case. The problem, which was not present in the previous case, is the lack of audio. I tried to make the change in config by inserting the line hdmi_drive = 2 to no avail.
Also tested with hdmi_drive = 2
hdmi_ignore_edid = 0xa5000080
hdmi_mode = 16
hdmi_group = 1
As per post, but the second command blocks the boot
Thanks for each vs. valuable suggestion
