No HDMI audio in Line x3, x4?

[Paranoid_Andy]

Hey everyone!

First of all I got an email asking if there needed to be any changes to the shipping because of the hurricane. I actually only just got internet back last night after 2 weeks XD but as a nice surprise my OSSC showed up today! So that’s pretty awesome and it came through okay so thank you for that.

I’m just getting things setup but I noticed an issue that I’m not sure if I’m doing something wrong or I need to set a special function but I can’t seem to get HDMI audio to work properly. Here are my current results and setup.

Setup:
SNES 1-Chip 02 outputting RGB to scart directly to OSSC.
OSSC HDMI out to ASUS VG248QE monitor.
Standard audio out jack from monitor to my speakers.

Results:
Line x2 Mode: Video and Audio through HDMI seem to be working just fine.
Line x3 Mode: Video through HDMI is showing, but there is no audio through HDMI, however audio from the OSSC 3.5mm jack works.
Line x4 Mode: Video through HDMI is showing, but there is no audio through HDMI, however audio from the OSSC 3.5mm jack works.
Unable to test Line x1 or x5 as my monitor may not support them.

Any ideas how I can get HDMI audio on x3 and x4? I’m hoping it’s just a simple toggle I missed or something.

Thanks!

***Edit***
I forgot to mention, I checked the other forum posts and the user startup guide but I didn’t see anything about this issue. If it is posted and I missed it, sorry about that.

Firstly check that TX mode is set to HDMI, then try a different HDMI cable and report back.

Hey thanks for the quick reply Bucko.

Here is what I did:
I went ahead and checked and TX was already set to HDMI. I then changed it to DVI then back, just to see but still same results.

I then swapped to another HDMI cable, different manufacturer. I then changed TX to DVI then back just to see if that might trigger it to kick in but still I’m getting the same results, 2x is fine, but no sound on 3x and 4x. I also went checked the TX mode each time I switched from x2 to x3 to x4 to make sure it wasn’t like resetting it or something but it was in the HDMI position each time I checked.

Would you like me to make a video showing what I’m doing?

[BuckoA51]

Sounds like you’re doing everything correctly. It may just be a quirky incompatibility with your display, but just to be sure can you try a different display?

[Paranoid_Andy]

Sure, I have a few other sets I can try. I’ll do that now and try to get back to you in ~15 min.

Well good news for you, but not so much for me it seems. 3x and 4x audio worked immediately on a Element HD TV from Walmart. So I seem to have a choice of either using 2x for HDMI audio, or just use the 3.5mm which makes it a bit tough for my streaming setup.

Is there a detailed guide I can follow about all the tweaks and adjustments I can make using the OSSC? I’m happy to learn, just not sure what info is the most up to date. I was curious to see if I could maybe get the x2 mode looking similar in aspect ratio to the x3 if I’m going to try to maintain the HDMI audio.

Thanks again.

Strange error indeed. Perhaps it is worth checking the menus on your monitor for a setting like HDMI/DVI mode, maybe even a firmware update for the monitor.

The most comprehensive documentation for OSSC is on the wiki:- http://junkerhq.net/xrgb/index.php?title=OSSC

However, remember OSSC is a line doubler not a full blown scaler, so please do not expect as much picture adjustment control as you might find on a Framemeister, for instance.

[Paranoid_Andy]

Ya for sure, I’ll go ahead and see about those settings and a possible update.

I was aware the options would be more limited compared to a scaler which is just fine by me.

What happened was I noticed that when in x2 and x4 mode the aspect ratio even though set to 4:3 generic looks like it’s in a widescreen format, but the x3 is like a perfect 4:3 and looks great. Just wanted to see if it was possible to make the other 2 have the actual 4:3 look as well but that might not be possible as far as I know as I could easily be missing something on how that works.

I’ll go ahead and read through the documentation you linked.

Thank you!!

I figured out the aspect ratio issue. In case anybody else with an ASUS VG248QE monitor has this issue, there is a setting for aspect ratio in the monitor settings that you need to change to 4:3.

Just a quick update for some more information that might be useful. When I tried my PS2 with SoTN the audio for x3 and x4 worked. I tried the SNES again but it still doesn’t. So I’m not sure what quirky thing is going on there but I figured I would let people know.

SNES mini with borti’s RGB bypass > OSSC 1.5 with audio board.

On this setup, I have to switch audio down sampling from on to off, then back to on again. Without doing this I don’t get any audio. Haven’t tested other consoles so I have no idea of the cause, but maybe this will work for you too…

Unfortunately NES & SNES 240p signals are prone generating stability/audio issues after digitization due to their inherent sync jitter. I’ll be soon testing an idea that could fix it, but it involves modifying the console itself (since that’s root cause of the issue).

[satchow]

I just got my new OSSC yesterday and I haven’t been able to get sound on any setting. I’ve tested it with my SFC, NeoGeo AES (both 240p) and my PS2 (480p) with component cables.

I did hear sound very briefly, for about 2 seconds, when I was messing around with some settings, but it went away on it’s own before I could figure it out.

I’m so sad, the picture looks amazing but everything is silent.

[BuckoA51]

Have you tried more than one display?

[marqs]

When using component input, make sure the miniature switch next to HDMI is set to “A2 in” position.
