PS1 with Picostation - weird sound glitches
Hi everyone,
I finally got my PS1 SCPH-5552 (PU-18)! I gave it to a local repairman friend who installed Picostation for me. The mod seems to be working fine. Menus load correctly, and games usually launch as well.
However, I've encountered a problem with the sound. The PS1 boot sound is mostly noise, with faint background sounds of what should be playing.
SFX in games is a strange metallic squeaking sound, but these sounds usually occur at moments when they should actually be played, such as menu sound effects when pressing the D-pad. In racing games, engine sounds are audible, but they're unbearably high-pitched and metallic like something from the NES, but the background music plays properly.
My PS1 works with an RGB cable connected to GBS-C. I've confirmed that the problem also occurs with the composite jack adapter on my TV.
I also made sure that only the pins indicated in the Picostation schematics are lifted on the CXD2925Q chip.
Where could the problem be? Are some of the capacitors failing or is it something else?
