Problem description:
When I set the resolution to 1360x768, which is the naitve resolution for my plasma screen, I get no sound over HDMI. I've tried all possible settings with pass through and such but no luck. No sound in the XBMC GUI neither.

If i set the resolution to 1280x720 the sound works perfect. Obviously I want to use the correct resolution so that my screen is in no need of scaling the output.

How to reproduce:
Change resolution to 1360x768

please check your log and pastebin here as mentioned in rules
in a meantime try to add this line to your config.txt
Code:
hdmi_force_edid_audio=1

Sorry that I missed the posting rule. Hopefully it looks better now. Anyhow I tried your suggestion with the hdmi_force_edid_audio=1 but it had no effect.

I don't know a lot about this,
but maybe you resolution is detected as DVI, so no sound.

I tried:
hdmi_drive=2
hdmi_force_hotplug=1
hdmi_force_edid_audio=1
hdmi_group=1
hdmi_mode=4

still sound, any ideas?

I think if you have a look at the command "tvservice" this might give you a better idea of what is going on. I can't remember the commands but "tvservice -a" gives an overview.

Also, have you enabled pass through? This might be causing the problem.

Also, try
hdmi_group=1
hdmi_mode=4


RE: No sound over HDMI 1360x768 but with 1280x720 it works - jonpa - 1st Mar, 2015 02:36 AM

I have enabled passthrough. But if I disable it whith the 1360x768 resolution there is still no sound. I ran the tvservice commands:
tvservice -s
state 0x12001a [HDMI DMT (39) RGB full 16:9], 1360x768 @ 60.00Hz, progressive

tvservice -a

It seems that it is still in DMT mode even though I have hdmi_group=1 and hdmi_mode=4 in the config.txt.

Can you run:
tvservice -d tvservice.dat
edidparser tvservice.dat > tvservice.txt
and post tvservice.txt to http://www.pastebin.com

What happens with hdmi_group=2?

here is the edid info http://pastebin.com/Y7EmzVcT

I will try hdmi_group=2

Can you post tvservice again but without any overscan or hdmi parameters.

From the original tvservice post, it looks like your resolution is not supported but that could be the forced parameters.


RE: No sound over HDMI 1360x768 but with 1280x720 it works - jonpa - 1st Mar, 2015 03:00 AM

Tried:
hdmi_group=2
hdmi_mode=39

39=1360x768 60 Hz

Still no sound. Stupid question, but the only thing I have to do to make the system read the config.txt is to reboot the RPi2 right?

RE: No sound over HDMI 1360x768 but with 1280x720 it works - IriDium - 1st Mar, 2015 03:20 AM

Yes but that mode doesn't have HDMI and audio support (If I'm reading the dump correctly) which would explain the issue. If so this is a hardware issue.

Can you try 1920x1080i @ 60 Hz (5)

hdmi_mode=5

Which should work.

What screen resolution do you get without any screen parameters in config.txt?

Yes, all you need to do is set the values in config.txt and reboot. They are read at boot.

The sound works with
hdmi_group=1
hdmi_mode=5

If I have no settingss in the config.txt it selects the one I have selected in the GUI. Don't remeber the resolution it had the first time. Where in the tvservice dump do you read that 1360x768 has no audio support?


RE: No sound over HDMI 1360x768 but with 1280x720 it works - IriDium - 1st Mar, 2015 03:41 AM

HDMI:EDID has HDMI support and audio support

The values above this value are ones that will work: So

#
HDMI:EDID found CEA format: code 4, 1280x720p @ 60Hz (native)
#
HDMI:EDID found CEA format: code 19, 1280x720p @ 50Hz
#
HDMI:EDID found CEA format: code 5, 1920x1080i @ 60Hz
#
HDMI:EDID found CEA format: code 20, 1920x1080i @ 50Hz
#
HDMI:EDID found CEA format: code 3, 720x480p @ 60Hz
#
HDMI:EDID found CEA format: code 18, 720x576p @ 50Hz
#
HDMI:EDID found CEA format: code 15, 1440x480p @ 60Hz
#
HDMI:EDID found CEA format: code 30, 1440x576p @ 50Hz
#
HDMI:EDID found CEA format: code 36, 2880x480p @ 60Hz

So you are saying that my receiver is not able to handle audio with a 1360x768 resolution?
