AQ Dragonfly works with Raspyfi10beta (https://sourceforge.net/projects/raspyfibeta/files/raspyfi.10betatest.rar/download).
]]>Could it be that the AQ Dragonfly only accepts 24bit? If yes, how can I feed my df with 24bit starting from a 16bit source?
]]>my dragonfly is not flying at all. I am close but at this point I have no clue what to do next, except ask you guys.
tl;dr
I have a metallic jitter which is louder than the actual music independent on the file I play (mp3, flac, etc.). This annoying sound is always present (not only at the beginning of a file).
What I did so far:
* Installed the newest berryboot and installed both, raspify and xbian.
* Applied the usb-audio-fix: http://www.raspyfi.com/raspber.....audio-fix/
* Checked performance of dragonfly on my notebook running ubuntu. Works perfectly.
* Connect to pi via SSH and installed gmpc on notebook. Connection is fine and working.
My pi is powered via a usb hub and an additional psu. when I measure the voltage over tp1 and tp2 its always around 5.02V while everything is connected:
external hdd -> usb hub -> PI -> Dragonfly <- simple psu (normally I charge my phone with it) using a Y usb cable.
Dragonfly -> nad c325bee or headphones.

Independent on the audio file type or source (sd card, external hdd, usb stick) I always have a metallic jitter during playback.
I do not know if the usb-audio-fix worked (it did not take 20mins, more about 2mins).
Another thing which puzzles me is why hw_params always shows 24bit depth (also with format "44100:16:2"). Maybe this is the problem but I have no idea how to change this.
Any help is appreciated, THX a lot!
]]>Bye and thanks for the feedback!
Could you please also post the name of the mixer bars (if there are) if you do
sudo alsamixer
? Thanks!
]]>This should solve the aforementioned problems...
]]>Con flac a 96Khz Si sentono spesso dei clip, con flac a 44Khz va un po' meglio ma i clip ci sono ancora.

Here is the output while playing the DragonFly with RaspyFi 1.0.
Maybe this is of any help.

Thank you, we're getting closer to the permanent fix!
]]>anch'io da giorni sto cercando di far funzionare il mio DAC AudioQuest Dragonfly connesso al Raspberry ma senza nessun risultato.
Escono fuori soltanto dei clip e rumori vari.
Se riesco a risolvere vi faccio sapere.
A post is coming also to show the complete situation, since I think lot of people will be interested in using the Audioquest Dragonfly with RaspyFi!
