Dear Jackal29a,
By following your smart instructions, I could play DSD64, DSD128, DSD256, DSD512 sources with both HQPlayer and JRiver Media Center without any problems. I'd like to express my sincere gratitude to you as well as to Domenico. Tomorrow I will connect the board to ElectrArt's "DSD Principle board" which is compatible with all the DSD sampling rates.
Best regards,
Bunpei
Hi all,
I really hope one of you can help with this as the hairs on my head are getting even greyer than they already are - & way before time - trying to solve this ...
I have made a DAC based on the DSD1794A and am now connecting it to the combo384 but I get no sound whatsoever. I've connected the combo384 as indicated in this post (#363):
http://www.diyaudio.com/forums/vend...-i2s-384khz-dsd-converter-37.html#post3173603
and have also tried to connect pin 7 of the combo384 (dsdoe) to ground as suggested in this post (#377):

Since I use the DSD1794 instead of the PCM1794 - and haven't yet tried to program the DSD1794's registers - I have connected pins 10-13 to GND, and pin 14 (reset_low) to VDD. Pins 1-3 for DSD connections are left floating (I've attached a copy of the DSD1794 pin connections).
All supply voltages on the DAC measure as they should and the DAC's current outputs are loaded with a 470 ohm resistor to ground. This gives ~2.6 VDC on each of the Iout+/Iout- outputs.
However, when I play back a 192 kHz/24 bit sample via foobar (amanero card selected) there's no sound whatsoever as measured by my scope. But there are signals that "look digital" on the mclk, fsclk, bclk and data pins of the amanero board. The fsclk, bclk and data levels jump from ~0 volts to about 3.3 volts whereas the mclk levels are between 0.8 volts and 2.6 volts. Yet, my scope (Rigol DS1042C) indicates the frequency to be around 22.7 MHz which is for a 512*fs at 44.1 kHz ??? I wonder how this could be ... maybe an oscilloscope artifact? The amanero driver I use is version 1.0.5.
When I stop the foobar playback the "DATA" pin level signals are now zero volts which I assume they should be.
Also, I've been thinking that maybe the DSD1794's registers are not set to accept PCM files in the I2S format by default but as far as I can see it should be so (I've attached a copy of the default settings - just in case one of you can "see through" this).
I honestly don't know what is amiss here so would really appreciate help from other insightful eyes & minds
Greetings,
Jesper
A P.S.: to Bunpei: Sounds really interesting - hope you will share your impressions of listening to particularly the DSD principle board and DSD512 ;-)
