Test the modified Amanero but failed. No sound

No BCLK output even at the Amanero. Since the Amanero output has resistor, should not be that easy to be damaged.

May be have to order another one

I'm keeping my eye on this thread, as I am too planning a similar project in the near future and want to draw as much wisdom/info as I can out of this thread to simplify my own build :P

Hi all,
I am stuck with a problem I hope someone can help me with.

After connecting my Fifo to my M2Tech Hiface evo (I2S output), my BII at the outlet of the dual clock and powered the Fifo with 5VDC. Everything looks ok but it doesn't play music, just silence.

My connection with Hiface evo.
M2Tech Hiface evo out: → Fifo in:
2,4,6,8) Ground → GND
1) SDATA → SD
3) LRCK (FS) → WS
5) SCLK (BIT CLOCK) → SCK
7) MCLK (Not connected)

My connection to BII.
Dual clock out → BII in:
Gnd → GND
SD → D2
WS → D1
SCK → DCK
MCLK (Not connected) since I uses the BII clock.

The fifo LED’s work perfectly and they seems stable. But no music comes out.
When connected and music played the Fifo led indicate locked signal. If I disconnect input signals and the led give the correct respons (the led goes black). The strange thing is that the led for Fifo buffer empty lights up (stable) even when music is played.

On the BII the led indicates that a signal has been locked and everything looks ok.

On the clockboard led for 512 and 44,1 kHz is shining.

You will find a manual on how to use I2S for M2Tech Hiface evo here: http://user.tninet.se/~pst442t/hiface_evo_i2s.pdf
The manual for Buffalo II here: http://user.tninet.se/~pst442t/Buffa...anual_v1.0.pdf


Greatful for all help I can get!

For info: My BII plays perfectly if the signal goes directly from Hiface to BII.

Hi Karvid,

Can you post pictures of your hookup?

Thanks,

Ian

Picture is OK.

It seems that the 7Pin PH2.0 I2S bridge cable connector on the clock board side has a bit loose. Can you confirm?

Ian

Ian,
I have double checked all connectors. And they seems all to be well connected. As well as the clocks.

After som handling has the led for empty buffer gone out (doesn't shine any more).

But if I disconnect the signals the Led says no longer locked signal and the buffer is empty. When I connect signal the led for locked signal is shining bright again and the buffer doesn't say emty any more (neither say the led that the buffer is full). So according to the led everthing is working.

This might be because I connected all of the gnd cables at input. I will try to do the same at the outlet and see if this will make a different.
