    I’m not entirely sure, but my understanding is that that TRS jack, when configured as an AV1 audio breakout, is just routing the audio directly from SCART to the TRS jack, without any processing at all; and that seems to be backed up by the behavior you’re experiencing. I think it’s possible but unlikely that both your cables are messed up in exactly the same way, so it sounds to me like there’s a bad solder joint somewhere between the SCART socket and whatever circuitry directs the audio between the OSSC and the TRS jack.

    Thanks for the reply! So something’s gone wrong inside the OSSC? The other thing is that my super famicom doesn’t have this issue at all… which makes me think the cables are at fault. I’ll do some testing my SFC again later once I get home.

    Just did some testing on the super famicom, and i’m 100% sure im getting stereo audio from it. Is there something unique about the PS2 audio that the OSSC is having problems with? Or is it just the cables… šŸ™

    That’s exactly right.

    No, nothing. I’m as stumped as everyone else.

    Since you’re not having any issues with the SNES, I think we can eliminate the OSSC from being at fault, and I think it’s entirely possible that both SCART cables or both PS2s are borked.

    If you have handy a PS2 composite or component cable, you can test your PS2s’ audio independently of the SCART cables and AV1 on the OSSC by connecting the audio directly to your AVR/TV (Or, with a female RCA to male 3.5mm TRS adapter, AV3 on the OSSC). If you get stereo from that cable, then it’s your SCART cables at fault; otherwise, I’d be suspicious of the consoles.

    I just tried using composite cables going straight from the PS2 to the TV and also tried the digital audio out on the PS2 to my headphones and the audio had no problems. Unfortunately I don’t have any of the adaptors needed to try using composite with the OSSC, but given that the SFC works fine with the OSSC I guess it’s okay to rule it out…? I’ll try getting in contact with retro access and see if I can get a replacement šŸ™

    Okay…. so I just tried my SFC again to be doubly sure and guess what…. Now the problem is happening there too!!!!! I can get stereo to come back if I push the plug going into the SFC with a little bit of force, but then the screen goes pink!!! HELP!!!! šŸ™

    If the image and sound is affected by how the SCART connector is seated in the OSSC, then that sounds like bad solder joints to me.

    Forgive my ignorance, but do you mean bad solder joints in the cable or the OSSC? The part of the plug which goes into the console was the end I was moving slightly to bring back the left channel of audio and also sometimes caused the screen to go pink…

    That honestly doesn’t make a lot of sense, but it might be time to RMA that OSSC just in case. Get in touch so we can sort it for you.

    I’ll get in touch soon, although i’m still worried it may be the cables at fault. I would hate to send it back overseas only for it to be working perfectly!

    If you’re in the USA you can send it to Mobius Strip.

    Just wanted to double check, I used the “contact us” page and it told me to look out for a message, but I can’t seem to find an inbox anywhere! Will I get an email?

    Thanks!

    I’m having the same problem as OP while using the PS2 through either component or scart, but i get stereo audio from my Wii with component.

    I wonder if there’s a compatibility issue with some ps2 models? I’m gonna do the composite test and also test my ps1 later to see if it’s the cable, but i don’t think it is
