Weak A4000 cd sound

[arttu80]

Hi!

I recently got A4000/040 and ofcourse has been very pleased with this long lusted C= marvel. I connected more modern DVD/CD drive to it with internal audio cable to motherboard CN404 --->

but when playing audio CDs I must really crank up volume knob on my amplifier to hear decently. When I run any Amiga software (e.g.games) CD sound output is much weaker compared to what is coming out of Amiga...Is there some advice to it?

You need some adjustable audio mixer.

It is a known issue, one theory is that so CD audio tracks in games would not drown out the SFX in games.  There is a fix but it involves replacing two resistors on the motherboard.

Thank a lot for the link. I'll try this HW hack with capacitor equipped resistors as stated in last post of that link (by Marcel).

The A4000T's AV Module handles the mixing of the CD audio and Amiga sound very well. The A4000 was always a compromised design in my view rushed out to combat VGA/SVGA PC advancements.
