today I received the new V4 kit with the 4 identical (balanced?) 6,35mm connectors.
Many thanks for the superfast delivery!
Assembly worked well, but I do not get the balanced output plug correctly connected. The cable colors of the balanced out do not longer match the tutorial (black has become GRD …) - that is easy to spot. But the 6-pin out-connector is nowhere documented, therefore tested a bit …
The layout on the board is
o o “R”
o o “GND”
o o “L”
The two center pins are common ground.
Looking at the labeled outer pin column: the “L”-pin carries a signal., the “R” pin is dead, no signal here.
The inner column (left ins the layout above) is
5V
GND
5V
Oh, well, that matches the hifiberry description of P5:
OUTPUT CONNECTOR P5
This connector can be used to connect to external components, e.g. an amplifier. The output is connected in parallel to the RCA jacks. Pin 1 is on the top left.
+5V

R
GND

+5V

=> I’m a bit confused now:
this is not a “balanced” output on the hifiberry in the new kit-4 (with removed RCAs), correct?
why is “R” dead with synth as well as with audio test? Did I miss something in the SW setup?
Thanks in advance for any hint!

Edit: I just checked and realized, that I’m the only one talking about “balanced output” in the context of the recent v4 kit (I got misleaded by the “balanced” cabling of the connectors).
Unbalanced connectors means connecting only black -> gnd and red -> signal, right?
But still that leaves the dead “R” as an open point
Hi jofemodo,
I think, the connectors are a minor problem - it should be possible to use thede connectors as unbalanced connectors (e.g. by soldering black and white together). Therefore, no need to send other connectors, I think.
What is more confising me is that I have not managed to get a signal on the “R”-pin, do you vave any hints or ideas here?
I suppose you are using the Buster RC-2 …
Did you try the audio test from the admin menu? It should generate stereo output, sound on both R & L. If you only get sound on one of them, it looks like a problem with the Hifiberry. In such a case, please, send me back the soundcard and i will send you a replacement ASAP …
The record function will allow you to record playback and copy audio in and out of the zynth and is very useful when doing this sort of debugging. Download the wav file using the webconf samples page and examine in something like audacity to ensure recording and playback actually respond properly via jack
if here is everything working I will do some checks with the record function as wyleu suggested.
I’m not shure, whether I can make that today - I’m in webex sessions until late evening and after that probably not in a state to deal with unsecured electricity ;-), but will report the results ASAP.
OK, bad news: I used another PI4 to install the hifiberry and used PiCorePlayer => same result: “L” has a signal, “R” not.
That looks like a broken hifiberry and send back @jofemodo: which postal address I should use?
Edit: found the UPS-label - will use the sender address, OK?
