Hi Pete

The value of the cap IS very important.

The improvements come from replacing the ceramic by a polystirene cap.

Merry Christmas

Reminds me of the first time I was tinkering with these players. I was measuring the bitclock and got 2.1168MHz, and I was like, huh? That's not 32*Fs, or 64*Fs, but 48*Fs, that doesn't make sense?? That doesn't match the 16 bit I2S output mode. Seems it just outputs 24 bits per word, and the DAC is set to 64*Fs, expecting 32 bits words, but because it's left-justified, it doesn't matter

I had a better read through the datasheet earlier and realised that I wouldn't be using the decoder as the digital filter, lol.

The datasheet isn't clear on how to use different clock frequencies though. As far as I can tell, it'll just work with any frequency between 8 & 35MHz. I'll need 11.2896MHz for the tda1541a.

I won't be able to do anything for a few days anyway so when I do I'll just have a play about and see if I can get it working.

Have a good one all, Lee.
