The 3.5mm jack and SCART socket audio inputs are a simple passthrough, so when the audio mod board hooks in to that, the 3.5mm jack is also connected to the audio mod board.Mikeyy00 wrote:I could if this is true?

Forgive me if it was actually that easy.

However, VGPerfection reports that connecting both a SCART cable and audio input to the 3.5mm jack at the same time causes the 3.5mm input to be very quiet. If you're only using the VGA and component inputs, this would work fine, otherwise if you also use the SCART input another solution would be required.
If it's a LVTTL (3.3V-level) signal then it should be fine. You'll just then need to modify the firmware by setting correct parameters for IT6613.Mikeyy00 wrote:Now how about running SPDIF into pin 4?

Thanks for the help guys! Haven't had a chance to mess around with this but by the sounds of it Low/Auto is the correct setting. I'll play around with test patterns and other brightness/colour settings soon.Harrumph wrote:I'd recommend using the 240p test suite to check the levels.
Also your TV should still have manual brightness and contrast settings right? I'd trust that a lot more than this auto level business.
I know I checked these settings before but decided to do so again, in case they changed value after a firmware upgrade. Now, the receiver seems to be accepting the signal, regardless of how these are set, when before it did not. Not the test image or any of the inputs.Guspaz wrote:The OSSC can output both DVI and HDMI signals, the physical shape of the connector doesn't have any impact on that. Have you tried changing the signal type between DVI and HDMI in the OSSC settings?
Maybe this is what's going on with me, a weak signal sometimes? I thought it was an odd problem in the first place, or maybe my receiver is just goofy.ZellSF wrote:I actually get image dropouts if I remove the HDMI splitter between my OSSC and DVDO VP50.

I had to reset my DVDO VP50 to factory settings because it suddenly felt like randomly introducing some sort of horizontal lines in the picture (either sync issues or tearing issues) frequently.
I can't wait until there's a solution that's less finicky and has less than one frame of lag. I think I'll be waiting for a long time though.
It's possible to boost TMDS output signal level but that shouldn't be needed unless very long cables are used, although it's hard to say anything definite about the signal quality without a high-grade signal analyzer.ZellSF wrote:I actually get image dropouts if I remove the HDMI splitter between my OSSC and DVDO VP50.

Had this on the older firmwares with my 50 pro but not any more, and only when switching between screen modes e.g 240p to 480i (VP50 would fail to re-sync).I actually get image dropouts if I remove the HDMI splitter between my OSSC and DVDO VP50.

Right, I had to do some thinking how I wanted to connect everything up. My HD consoles are routed through an HDMI switch, and then connected to one HDMI input on my receiver. The OSSC is connected to it's own input on the receiver, and feeding the OSSC is an extron matrix switch with the older machines. So hopefully there won't be any interference with re-syncing, but I haven't tested it thoroughly as I'm still waiting on some cables to restock lol.BuckoA51 wrote:One problem with splitters though adding them to the chain usually adds at least an extra couple seconds to re-sync time, so if you're trying to play games with 240p/480i transitions, splitters make those transitions take even longer, in my experience anyway.
Both the cheap China HDMI splitters I have manages to sync in less than a second, total. Would be pretty good for playing 240p>480i games if it weren't for the fact that the VP50 displays a ugly blue screen when the signal is lost for that second.BuckoA51 wrote:One problem with splitters though adding them to the chain usually adds at least an extra couple seconds to re-sync time, so if you're trying to play games with 240p/480i transitions, splitters make those transitions take even longer, in my experience anyway.
I just ran into this myself and am kinda annoyed. I'm feeding my Extron Crosspoint switch to the SCART port of the OSSC for RGBs and YUV, and Dreamcast (and maybe X68000 after I test that) on a VGA switch into the VGA port of the OSSC. Even with no inputs routed to the output on the Extron, it still makes the 3.5mm audio quiet unless I unplug the audio connection going to the SCART port. I assumed that if both audio ports were not in use at the same time that I wouldn't encounter issues.Guspaz wrote:

Oh that's a good idea, I was wondering how I wanted mine setup too. Was planning on having it connect directly to the OSSC, since everything else is coming in through the SCART input. But you're right I can just have a different extron output go to the VGA input.BuckoA51 wrote:Route all audio through your Extron crosspoint and through to the SCART and don't use the 3.5mm input at all.

I use an Extron as well (two actually since I'm crazy. One for scart inputs, one for everything else). I don't use the VGA audio on the OSSC at all. I use the Scart input, and the VGA input (nothing on the component end). Since the Extron can do multiple outputs at once, I send the signal to both the Scart and VGA on the OSSC. That way, the audio from the VGA and component signals is sent to the Scart input on the OSSC and the video is sent to the VGA. I send all video to the VGA because it can handle everything (RGBS, RGsB, YUV, RGBHV). The audio is perfectly clear and the video is perfect.cr4zymanz0r wrote:I just ran into this myself and am kinda annoyed.

I'm trying to figure out a graceful way to 'fix' this, but so far the only idea I'm coming up with is installing a switch on the SCART cable hood to turn off (disconnect) audio going to the SCART port.
15khz sources are usually more suited to the AV1 input, AV3 does not have the same low pass filtering.I use an Extron as well (two actually since I'm crazy.

Sixteen inputs?
