I have my Raspberry Pi configured as a media player and it has worked very well (1080p and 5.1 audio) until yesterday, when it started to output only 720p video and stereo audio over HDMI.
If I use hdmi_drive=2 and hdmi_force_edid_audio=1 I have 5.1 audio, but I have no luck with video.
I've tried using hdmi_safe=1 or hdmi_group=1 and hdmi_mode=16, but the output is always 720p. I've tried also several values for config_hdmi_boost.
When I use /opt/vc/bin/tvservice -m CEA to find which formats are supported, I get this:
Code: Select all
Group CEA has 0 modes:
Is it broken? Or is there anything left that I can try?
