HDMI sound + other HDMI questions

[rolle]

Tried playing with HDMI for the first time today.

1) HDMI on the fly switch - was it supposed to work yet or not? When I plug in HDMI nothing happens, I need to go to menu, enable HDMI, it shuts down, then need to start again, then HDMI works. Feels like a lot of trouble just for getting HDMI on.

2) When playing or browsing video previews, audio comes from RetroStone and not from TV, how to get this as automatic a possible? If not automatic, how to switch it manually?

3) Aspect ratio / resolution. I'm not sure if 16:9 works for NES for example, should it be 4:3? But I I switch to 4:3 from TV, everything looks squashed. What's the deal here, how this should work?

1) feature still in development: https://www.kickstarter.com/projects/583...ts/2831539
2) HDMI audio is not yet supported in kernel: https://linux-sunxi.org/Linux_mainlining_effort
3) You can open Retroarch menu and change Settings - Video - Scaling (use Overrides option from quick menu to save your changes) or tweak retroarch configuration file directly - /opt/retropie/configs/all/retroarch.cfg or platform specific /opt/retropie/configs/nes/retroarch.cfg . aspect_ratio_index = "21" should be fine
from retroarch documentation: 19 = Config, 20 = 1:1 PAR, 21 = Core Provided, 22 = Custom Viewport

Thanks, I'll try these. Too bad about HDMI audio as it's kinda the point in HDMI, but having high hopes for the support.

HDMI audio patch is being submitted/reviewed by OLIMEX, so it should be there soon
in the meantime, i use a 3.5mm AV cable to output the audio
