Taito Cup Soccer, very low FX and extremely high music

[Tailsnic Retroworks]

Hi. I am trying to figure out this issue. I have a Taito F3 white single board which has a extrange problem. The FX sound is extremely low and the music is very very high, even a little cracking. I have recapped all the audio zone and even replaced de TDA1543. Is this related to something in specific?

Might sound stuupid, but isn't there a way to adjust FX and BGM volumes in the test menu ?

Don't worry, this issue is indirectly connected to conversion issues of Taito V2 sound types. Thanks for answering me.
