Hi,
The project of the controller for CD ROM has very much liked!
Unfortunately I do not know the Japanese language. But the controller all the same has made. Tried to work with CD ROM
Philips PCX32CD and NEC3002. All functions work, except for one - "PAUSE". In this mode on S/PDIF
There is a signal and unpleasant singing is audible. Tried different programs - from v2.2 up to v2.6. In all cases
In a mode "PAUSE" singing is audible and the indicator of a signal on S/PDIF on DAC shines: (
How it to remove? May there will be new versions of the program?
And still a question.
May it is necessary to take the data not on S/PDIF? May be it is necessary to take the data on IDE? Probably AT90S8515
with
It will consult(cope). Certainly it is required additional RAM.
I wish good luck in your projects!

What is "PAUSE" ?
I don't implement pause function on my controller.
Did you implement original function ?
Or you call stop function as "PAUSE" ?

If you mention the stop function, no sound will be heard during stopping. It may be happen only Philips PCX32CD and NEC3002.

I think it is possible only to send mute command through ATAPI command. Just "MUTE" command does'nt exist, but
ModeSelct command may set mute mode of output port.

Of course, it is possible to eliminate unpleasant singing by operation S/PDIF signal.

Thank for the answer.

Yes, I was mistaken. Button Pause is absent. The signal on spdif does not disappear while translating the controller from "Play" in "Stop". Thus there is very unpleasant sound.
So occurs and at loading a disk by button " Eject ".
Probably the mode not correctly works for me "Stop".

Yes, probably it is problem Philips PCX32CD and NEC3002. It is sad. I have only these drives.
It is necessary to buy something another :(

Automatically to switch DAC in "Mute" on a signal "spdif" will fail. If the sound the signal "spdif" goes in a normal format is taken. Sadly, but I am not able to program AVR.

Yes, it is a problem of mine CD ROM :(
With other models the controller works well!
The project will develop? New opportunities will appear?

I'll continue development of this project.

But i don't have your troubled CD-ROM drive, so i can't research its cause.
