I don’t remember this being an issue with the LCD Deck, but my OLED Deck is really noisy when using wired headphones (e.g., hissing, chirps, etc…). Anyone have this issue on either version?
I just checked and I have the same thing on my 512GB OLED. This is a hardware bug. Sounds like system and audio grounding haven’t been properly separated.
It sounds quite bad, makes me wonder how this made it past QC.
One, not really acceptable solution, is to use a USB-C to headphone adapter. I just tried the cheap Apple one and it works perfectly. My Zorloo Ztella also works. My passive OnePlus cable doesn’t work, unsurprisingly.
Downside of that workaround is that the adapter will consume a little bit extra power.
I wonder if I could swap the old board with the new. They aren’t the same, but worth a shot.
Maybe it’s just software. Did you try on a preview/beta build too?
I don’t expect you could swap out the boards, a lot of the components have changed.
I’m quite sure this isn’t a software problem. My official Sony PSOne display and MiSTer FPGA have the same noise and it is caused by the grounding problem I mentioned.
Should it be the headphone wires inside picking up the noise, a shielded cable might fix it. But I don’t expect that to be the cause of the problem.
Just saw your other response about the iem sensitivity.
I’ve tested a few pairs of earphones and a pair of headphones (Very noisy: Sennheiser IE80, no noise: Philips Fidelio X2HR, Phonak Audeo PFE 112) and it looks like ones with 16 Ohms impedance exhibit a lot of noise, while 30 Ohms and up ones are silent.
Ugh no bueno. I have Sennheiser ie900 they I think are 16 ohms. That would explain something. I haven’t had much time, but I’m curious to see if I could just swap in the old LCD audio board.
I’m not sure if both have a separate audio board. I’ll try with my Senfer DT6 as well, those are great and relatively cheap. I also have some other in-ears and headphones, to confirm that the impedance is the important factor.
I also experience some static and noise when using a standard 3.5mm jack headset (e.g. Apple Earpods or similar).
However, in my case the external mic input is even worse! My Apple Earpods with 3.5mm jack sound totally fine on other laptops. However, on the OLED deck the mic volume is expectionally low and I get a lot of noise in my recordings (high pitched chirping and static). Can anyone try to record his voice with an external mic for a couple seconds and listen to the playback to confirm this?
Same with mine, hissing on headphone jack
