Hello everyone!

First, I would like to address a big THANK YOU to Triode for an great
app I've been using since it's been released!

I tried many DAC with the SBT and all of them worked except two:
- The Resonessence Labs Concero which I just received
- The Asynchronous firmware of my Audio-GD DAC featuring the VIA VT1731
receiver (NFB-27, Reference 5.32)

The Audio-GD works flawlessly with the #3 firmware that features
*adaptive mode*.
I tried various DAC featuring the Tenor 7022L chip (Fostex HP-A3,
Audio-GD NFB-3.1) in *adaptive mode*: they worked flawlessly as well.

So far, the only USB interface that I managed to get working in
Asynchronous was the Stello U3 (X-MOS).
It had one issue: the U3 must be powered *before* (and, of course,
during) the boot of the SBT, otherwise the LED stayed red (no sync).
Once the SBT properly booted, I could unplug/plug the Stello U3 and it
worked flawlessly. So each time I moved my SBT (power off), I had to get
a powered hub to power the U3 before booting the SBT. That's not really
convenient but a minor issue nonetheless.

The Audio-GD in async mode outputs sound, but it is choppy and heavily
distorted, as if some samples were mixed between channels. I managed to
get it work properly only once (luck) but never could have it working
properly after that. I have no problem in adaptive mode.

Then comes the Concero.
I don't know what USB receiver it uses (if any). I know it has FPGA for
processing duty. Maybe it does implement the USB receiver? Pretty much
like in the X-MOS.

The Squeezebox recognize the Concero and the status says:
-Status: Running
Speed: High
Connection: Direct
Type: Async
Frequency: 48281 Hz
Feedback: none
Interval: 250u
-

Anyone experienced something similar? I tried with a powered hub with no
success.
I noticed that the Resonessence Invicta has some issues with the SBT as
well (on the compatibility list).

Also, I read everywhere one should update to kernel #14. Where can I
find this one? On the applet installer, I get a version 8 of EDO and no
specifications regarding the kernel.

Thanks :)
Clem
