1) I have tried to force sound though HDMI on 1.313 and 1.4 No dice!!
(I noticed you mentioned the config.txt.. Where is the information as the remarks in the file
are not too helpful)
2) MC displays fine in 1.313 but doesn't look good in 1.4.
3) My compact keypad mousepad works in 1.4 but behaves badly in 1.313.
However my main issue is the sound, can I get it through the HDMI or not?
Sorry... One more..
When Uae4arm thows an exception. Amibian can't handle it and a hard reboot is necessary..
The touchy mousepad keeps selecting configurations without roms and Uae4arm shuts you out.. It happened when I select a "too high" resolution..
Okay... I solved the sound so my v1.4 is working beautifully... The display corruption on MC is still there but I can live with that ( it still works)
For all those who have sound issues, the Raspberry does an auto check "EDID" and it reports that your TV has no HDMI but a DVI... There is a list of resolutions here https://elinux.org/RPiconfig
I have use hdmi_group 2 and hdmi_mode 86 and changed the hdmi_drive to 2..
Thanks Gunnar for this firmware... A whole lot of hard work.... Cheers
