Hello all.
I have purchased a Music Module, and I posted here some days ago how to take out the music ROM. When I first tested it, there where no sound at all and I thought that maybe I didn't know how to use the program (weird...). Thank to your comments, I took out the rom and yesterday loaded some music demos. No sound again. Then I connected the Music Module to a pre-amplified speakers and I realized that the sound was ultra, ultra, ultra low turning the volume at max.
I have a MSX2+ A1 WX.
Anyone knows what might happen? :(

Could you clean the music module pin with alcohol and try again

Do you mean the cartridge connectors? The bottom ones?

The cartridge connector as they seem half rotten . So maybe the power supply is not at its best

That's too low volume indeed... clean the connectors as they seem to be a tad too dirty... When done, the music module is still low on volume and that's normal... If you want to have it at the same volume as your internal MSX-Music, change this resistor with the resistor on this pic:

Hmm... Looks like either the arrow points at the wrong resistor, or we have two different music modules
Some guru might want to clear this up?

I would not like to be a person telling you the bad news, but I think your Y8950 has blown up.

Do you use the external sound output connector?

Yes, first at TV no sound at all, then via stereo RCA to external speakers... nothing at all. low, low, low, low, sound.
