Audio GD i2s Output - PS Audio

[arnaldo]

Hi guys, i have a Raspberry Pi 2, RuneAudio (great, the best) last version, DAC PS Audio PWDMK2 -> USB all is ok, sound fantastic.

Now i bought an AudioGd Output Module i2s(via HDMI) try to upgrade in sound.

PIN 12 - BCK
PIN 17 - 3,3V DC Power
PIN 34 - MCK
PIN 35 - LCK
PIN 39 - GND
PIN 40 - DATA

I tried hifiberry dac driver but does not work.
Any suggestion?

Thanks,
Arnaldo.

Hi Frank, my dac has a hdmi input.
Which driver i have to use?
I try hifiberry dac but nothing.
i think the problem is only the driver...or not?

thanks,
Arnaldo.

Hi arnaldo,
The HDMI standard has no I2S connections. In your case HDMI is just used as a connection cable. The pi can supply an I2S signal and with a custom (diy) cable you can connect your dac. But, the pi can NOT supply a master clock (MCK) signal. You need to check if the MCK signal is essential, optional or not required. Some dac's need it and others don't. Next steps depend on MCK.

Hi Janui, i know that hdmi is only a way to send i2s signal, infat my DAC (PS Audio Perfect Wave DAC MK2) use this.
My questions are:
- wich driver i have to use in RuneAudio for enable i2s connection via Audio GD card
- is right my pin map for i2s
01 - Power 3.3V
12 - BCK
34 - MCK
35 - WCK
39 - Ground
40 - Data


my custom streamer:

Hi arnaldo,
A Picture says a thousand words, nice streamer.
You need the HifiberryDac driver.
This diagram explains the connections you need to make:
Replace the P5 with your HDMI pinout. There is no MCK output from the Pi.

Hi Janui, i have google too.
I have seen that picture, LRCK is in my module WCK.
I just tried this pin map, now I'm not sure that problem is this or module or PS Audio DAC.
This morning i have writeed to PS Audio for a help.

Thanks for all!
Arnaldo.

Update:
one good news one bad news...

bad: PS Audio Perfect Wave MK2 DAC needs MasterClock signal in i2s connection, the new DirectStream no. In Raspberry 2Pi there is not a Masterclock pin.

good: i think i have found the solution using this card

i could have what PS Audio Perfect Wave MK2 DAC require.
