    Hi folks,

    I’m almost ashamed of this – I considered myself a pretty proficient console modder once upon a time – but I botched the installation of the audio board on my 1.5 OSSC. I didn’t cut the traces to ground all the way the first time, and in the process of disassembling it again tore up one or two of the pads. I ended up getting it working but using a scalpel to help lift pins 9, 10, and 11 of the IT6613, sliding the board under, and soldering the legs down.

    It works fine on my main TV (will post in the compatibility thread in a bit), but when connected to my PC’s Asus MG279Q monitor the audio clips like crazy and sounds awful. Has anyone experienced this? It sounds like the SNES is run through a guitar overdrive pedal or something, and gets worse as the pitch goes up. I did a search on this forum and Google in general and couldn’t find anything.

    Did my old, shaky hands do permanent damage to the audio board, or do some screens just not agree with it? I dabbled with all the audio settings and nothing made it sound right on this screen.

    Do all consoles do this or just the SNES? It Could be related to the SNES jitter issue – https://videogameperfection.com/forums/topic/nes-snes-240p-audio-video-stability-issues-read-before-posting/

    Ahh crap, I didn’t even think about that for audio, just assumed it’s fine because the video has always worked flawlessly on it, but you’re 100% right here. I plugged a PSX into it and the audio is fine, that’s a huge relief!
