Feeling guilty about taking up so much bandwidth and indeed,contributor's time, I thought this thread might be of general interest as a separate issue. It does of course relate to the other problems but I'll try to keep it specific to SPDIF - This picture however, is ripped from t'other thread.
This is all I have. If there ever was a ribbon for this, I didn't inherit it. It tallies with the scope that there is only one pin on the connector that carries data. Struggling to use improvised leads, I failed to note the frequency of the "carrier" Do they call it that? But 40khz is not out of the ball-park.
It is obvious that a very definite device for de-coding has to be on the end of whatever cable/fiber that I end up using. Sadly, my 'Clearance' Sony 50 CD/tape/radio thing, only has CD optical OUT in addition to the very basic RCA sockets IN.
The computer has these few pins. HDMI and DVI. They are marked OUT. So any hope of using my Sony UP Converter DVD player INTO the computer, seems stymied.
At the end of the day, there is a signal on that 3rd pin, I guess I need to try it into a suitable device to see if it works, then go from there.
Funnily, as mentioned on the sound FAULT thread, the sound was going last night, and is still going this morning.
