the BBB has no problem working with 45/49 master clk input, if you set the kernel accordingly
mcluxun, can you confirm that you're using the master clock output from the Soekris DAC to clock the BBB (setting Botic config parameters to 'external' for 45 and 49)? I'm looking to use the same setup when I get around to trying the Soekris.

Tonight I've been playing with JRiver's DSD conversion function; I've converted a couple of FLAC rips to DSD64 and DSD128 (dsf format so tagging works) - you end up with big dsf files (a 463Mb album in FLAC becomes 3Gb (DSD64) and 6Gb (DSD128) so converting a whole library isn't something to be done lightly, however, it does mean I can do some comparison when I get DSD capability on my DAC sorted out.
Conversion was pretty processor intensive so I have a question mark about 'on the fly' transcoding?
Acko, for info, I've been serving the DSD files from the beta V5 of Asset UPnP without a hitch; it's looking very promising.
BTW, does the ESS9018 digital volume control still function with DSD material? Just checking as I've been using it as my only volume control and don't want to damage anything by finding DSD plays at max.

Ray, thanks for the update. Look forward to the release version.
I would think any transcoding will affect the final sound quality so best to keep in native format other than for test purposes. That is why I am looking for UPnP server that 'streams' DSD natively
On digital volume control for DSD, I haven't seen issues with my setup. Also, there is nothing in the datasheet that indicates any precautions for the 9018. Other DACs like AKM4490 do, and require Vol control bypass. in fact even DSD detection requires I2C setting of registers for the AKM series.

Hi
Im using the 9018 and have been testing DSD64 to DSD512. the internal 9018 volume works well on all..

There you go Ray, you can now test DSD with confidence
Over the Weekend, we did another server shoot out at a mate's moderate setup. This time the room was less than optimised, and the setup is approx $60k. While it was crystal clear the Banana Pi has won the heart of our audience last gtg, it was not all that apparent with this gtg. The participants posted their observations here ==> Music servers & streamers; SQ comparisons - Page 5 - Digital, DACs & Computer Audio - StereoNET
It's been quiet here for a few days, perhaps Acko is in the kitchen cooking up a treat?
Actually, just waiting for delivery! ETA next Monday. In the meantime double-checked everything and could not see any issues, so all pretty much ready to go

I hope you didn't read that as me hassling you - was just meant as a little humour
and besides, it's not long to wait as it's already Friday where you are.

Good news! Any pics of the new board?Actually, just waiting for delivery! ETA next Monday. In the meantime double-checked everything and could not see any issues, so all pretty much ready to go
This available Kemet part matches value and physical dimensions of the BOM Epcos/TDK part in the prior post: PHE426HF7470JR06L2
Seem like a good substitute for C4*?

Looks great! Go for it
BBB-I2S/DSD
Its here now!
See my webpage for more details and ordering information....
Its here now!
An externally hosted image should be here but it was not working when we last tested it.

Not offering bare boards this time???
No, there are tiny components on both sides plus a micro that needs to be programmed in-circuit.

Good on you Acko!
Evaluating DSD audio just got a step closer.
