Tiny DAC, Big Sound, Evolved – Stoner Acoustics UD100 / UD110 / UD120
Oct 17, 2013 at 7:38 AM Post #377 of 1,162
  I tried to get the UD110 working on my Raspberry Pi but could not get it working properly, sometimes it worked, most times it does not. Have not tried your test yet though..

 
Those are my experiences as well.  Sometimes it will show up as a valid sound device and looks like everything is right (speaker-test starts without errors) then midway through it errors out.   Maybe a new release of Rasbian will fix it some day.

  Stoner Acoustics confirmed that they are working on a DAC based on ES9018, which is still under prototype progress.
They had uploaded a teaser pic on their Facebook page a long time ago, but provided no info...
 
Here's the unit: Big Man's Toy (as labelled by Stoner Acoustics)
 
 
 
I may be wrong, but it looks like it has balanced output...

I know I am late to this party, but that almost too tiny to be a full ES9018 dac.  Most of them are huge.  The only exception is the Resonessence Concero HD, which uses the new M version for low power stereo implementations.  It will be very interesting to see what they can do, especially if they can keep the value pricing of their mini sticks.  Is their a development thread with more info anywhere?

Please let me clarify: I'm not guessing or assuming that it is based on ES9018 dac; in fact, I specifically asked Stoner Acoustics about this very device, to which he replied as I stated.
And yeah, their products are absolutely VFM.
Also, there isn't any other thread centering around products from Stoner Acoustics AFAIK.

OTG to DAC doesn't work?

no. it doesn't

  When someone else receives their UD110 and has a Linux box or Raspberry Pi, can you test it and see if it works?
 
pi@Raspyfi:~$ speaker-test -c2 -D hw:0,0
speaker-test 1.0.25
Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 262144
Period size range from 48 to 131072
Using max buffer size 262144
Periods = 4
Unable to set hw params for playback: Input/output error
Setting of hwparams failed: Input/output error
pi@Raspyfi:~$

 
I get the same problem:
pi@rpistudy ~ $ speaker-test -c2 -D hw:0,1
speaker-test 1.0.25
Playback device is hw:0,1
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 262144
Period size range from 48 to 131072
Using max buffer size 262144
Periods = 4
Unable to set hw params for playback: Input/output error
Setting of hwparams failed: Input/output error

 
 
The result of aplay -l is :
 
pi@rpistudy ~ $ aplay -l
