New FIFO buffer for RPI/SBCs

Hi ,

we are working still on this...so what we have found so far is that PLL of DAC IC has to be set (mck or bck)...then DAC SK mux is in autodetect . Our testing so far... dont take this as 100% tested...is that DAC SK might take the outside SCK when present. Anyway , we will post soon the final results.
 
Hi,
Is there a way to control reclocker buffer length by software ?
I'll like to have the possibility to disable FIFO latency for certain usage scenario (real time network audio) and to re-enable normal buffering for normal reclocked listening.

Is it doable ? Is the reclocker board addressable via I2C or SPI from SBC ?

Thank you,

You cannot change/disable the buffer
 
ok, well not ok actually. I've made a Volumio sd card image to be able to alter the crossover frequency. Selected piano dac 2.1 and crossover at 100Hz. Result: volume of sub is always 100% does not respond to Volumio software volume. Monitors do respond to volume control. And dspflow is now corrupt, I think. Went back to Moode audio 3.0, volume does respond to both sub and monitors. But there is no crossover anymore. Monitors get the full frequency range. :(
(Raspberry pi2 - kali 44/48 - piano dac 2.1)
I did a request at TI for pure path studio, but that has been denied. Second attempt to obtain the software has been sent. fingers crossed

I've just ordered a Piano 2.1 so I do very much hope there's going to be a way of controlling sub plus main speakers in tandem?
 
Hi !

I want to share here my great satisfaction with this Fifo clocker. It helps me to connect an external DAC AK4495SEQ to a Raspberry PI2 via I2S. Due to the fact that the AK4495 DAC has no clock, I use the pin 29 MCLK and the DAC works nice in synchronous mode with KALI.

The Mamboberry DAC+ was on top of the KALI before. So switched off, removed it, connected the 5 wires comming from AK4495 to KALI conector, switched everything on, and it immediately started to sing ! Still Mamboberry driver in use with Moode 2.7. Changed nothing on software side.

I am blown away by the new sound, some additional details and better stereo . It's for me a new level of quality even with this cheap implementation of the AK4495. Was not sure it will work, but finally it was easy. KALI is indeed a very good piece of hardware. And AK4495 seems to be a good one too.
