ProtoDAC TDA1387 X8 project

[speedy210]

Any generic DAC settings will work. ProtoDAC does not identify itself to the OS. You can also install Moode, use the named I2S DAC ProtoDAC TDA1387 X8, and then use the Squeezelite renderer in Moode.  That way you can easily compare the two.

Moode has much better sound quality.

I will definitely test Mood. Unfortunately I had problems writing the image to an SD. I wanted to test it on a Raspi 3B, but something did not work and the system does not start. I used the latest release 64bit. I had the same problem with Picoreplayer, and only the 32 bit versions work on the Pi.

Did you read the set-up documents and follow the sd-card installation tutorial there ? (using the Pi-Imager)

Yes, I had read that. I unpacked the rar and then flashed it with the Pi imager. I'll try again tomorrow.

Moode image is is shipped in a zip file not a rar file, and no need to unzip b4 using the Pi Imager

Ok, then it was my mistake. I have unzipped the file. Thanks Tim

So the Protodac runs perfectly. The problem with the Raspi was that I had a Raspi 2 instead of a Raspi 3. The packaging was from a Raspi 3, but the content was the Raspi 2, so someone cheated me. Nevertheless, everything is working now. Thanks for your support here. I am very enthusiastic.

I have finished building my ProtoDAC and, well, it plays. No cracks or pops except for really small ones when you change tracks. No audible difference between the left and right channels. The left/right test track also seems to confirm that everything works as it should.

But now to the problem: if you turn down the volume so low that you cannot hear the music (volume max in Moode player, only changing the volume on my headphone amp), I can still hear a ringing sound that goes up and down in frequency repeatedly. It vaguely reminds me of coil whine, but it's not as annoying. Offcourse you can also hear it in not so loud parts of the track, like in the beginging of Bruce Springsteen Thunder Road (Live at the Hammersmith Odeon, London '75).

What is that and how do I get rid of it?

I have tested it with my CD player plugged in to the headphone amp and it is dead quiet

My gear:
RasberryPi 3B+
Stock RasberryPi power supply
Crack OTL Headphone Amplifier 
Headphones Sennheiser HD 650
ProtoDAC kit baught from ebay, username, kinkin0000
old CD-player, Sony XA-20ES to test and compare with
previous DAC, SMSL M8, now broken.

Volume is turned down on the HPA, but you hear the noise through the headphones?  If the noise is through the headphones, it would suggest that WiFi might be responsible. Maybe the HPA is not adequately filtering RF from the WiFi. Does the noise stop when the track is paused? Try turning off WiFi and use an ethernet connection.

On the HPA, I think the volume pot is on the front end of the amp. Anything from the RCA will be attenuated when the volume control is turned down, which would rule out the ProtoDAC. The HPA is still sensitive to RF, which will still be amplified. The CD player doesn't broadcast RF.
