I don't need the entire analog I/O board, wouldn't fit in my intended case anyway ... so I just built the audio part from the (easier to read) 5.2 schematicijor wrote:How are you connecting the analog audio?

128mb sdram, hdmi video & analog audio connection.
You would need to fool the core into thinking that the analog board is connected. At the minimum ground GPIO1 pin 10 by connecting it to pin 12. Please check (and double check) the schematics to be sure you know exactly what you are doing !!!Coffea wrote:I don't need the entire analog I/O board, wouldn't fit in my intended case anyway ... so I just built the audio part from the (easier to read) 5.2 schematic
It should. I don't have a 128MB SDRAM board to test actually test it, but support for the newer SDRAM boards was implemented already in a an earlier version.hex wrote:Does 0.17 work with 128MB?

The only monitor I have that passes though audio from HDMI adds some distortion for some cores / passes no audio at all for others (don't have anything so fancy as a CRT). So I've switched to a screen without audio at all and drive a separate speaker set directly. This does provide sound output on everything I've tried with the exception of fxcastijor wrote:You would need to fool the core into thinking that the analog board is connected.

Be aware that the core would then drive all the signals that normally output to the analog I/O board, such as the VGA signals. That is not a big problem as long as nothing is connected. Make sure you don't connect anything incompatible or you might damage the board.
Btw, just for curiosity, why do you use analog audio with digital video?
I have a 128 and might have just been lucky, but so far I've not found a core that hasn't worked.ijor wrote:It should.

Six down, changes between auto and 60Hz here, with HDMI connected.telengard wrote:Could someone please post the number of menu items down the Pal/Ntsc choice is? The core defaults to PAL on my 15Khz and I can't change it.
15 KHz is currently not supported. VGA output is always scan doubled. It will be supported shortly, but not yet. Sorry.telengard wrote:The core defaults to PAL on my 15Khz and I can't change it.
