You are using the sole channel A of the PSG.
It may be a problem in the setting of register 7 (mixer) where you have by accident disable the sound in channels B and C
You can see the problem in MEISEI under Advanced/PSG Toy
It will show visually the PSG data of the active channels
EDIT
it is not the MIXER, you are writing a single channel
I honestly have no idea what this is about. : /
I use the default WYZTracker and AsmPlayer settings.
Can you explain exactly where the problem is? I probably don't know something important.
Try first to see if your songs in the test program that come with the player sound correctly
WYZTracker/AsmPlayer/Prueba_MSX.asm
If they work there with 3 channels the problem is in your code.
In this case only a debugger can help. I would look at the part of code where you mix music and sfx.
It could be a problem there. Maybe the wrong sequence of actions.
I would set a break point where you copy the psg data to the psg register
Look at that first
That's exactly what I did, the music works identically to Prueba_MSX.asm and in WYZTracker itself. Additionally, I am using exactly the same code, my Init code:
