How to connect my Cell Phone to my DAC?!?!


Hello,

i have been told it is possible to connect my cell phone directly to my DAC and play music from the phone, but can't figure it out.  :(  DAC is showing "44Khz" message so it KNOWS that something is connected to it, but it never plays any music.  I am using an "Audio USB" cable from a DJ supply company.  The same phone and same cable work fine going into my Hegel Amp (internal DAC) but no sound comes through when trying to use EXTERNAL DAC.  The item in question is the SMSL SU9n.  I cant find any email contact at SMSL.  i wonder if anyone here would know how to troubleshoot this problem.  Thank you for your comments.

@audphile1 you are probably closest to the truth !

This morning, tried to play Spotify on JUST the phone speakers and the volume WAS set on zero.  Even after i manually turned it up, would not even play on the cell phone speakers.  After re-starting the phone, it WOULD play on the phone speakers.

So, now, i am thinking it is not the DAC at all.  Something between my phone and Spotify...   Android Motorola $85 special, lol.

DAC works with Bluetooth and with Optical  but does not work with USB input.

Same behavior when connected to 2 different Amps.

Phone works with Hegel and with USB, just to show that the USB cable is not at fault, and MAYBE the phone is not at fault.

So the SMSL DAC does not make use of the USB input at all, but it does recognize that there is something plugged in.  (768KHz note lights up).  There is either a SETTING somewhere that is making the DAC incompatible with the phone or the DAC is totally defective when it comes to using the USB input.    :(

 

 

 

...some additional information.  The APP i would attempt to run on the Phone is Spotify Premium. 

DAC is going into a different amp, the SMSL DA-9 with Balanced XLR cables.

The Hegel is not really involved.  I just used that example to show that the phone and cable are working.

Thank you @loomisjohnson   The story comes to an END.

i did try Youtube on the phone - same bad result.

Got me thinking why not try the desktop computer?!

BAMMM !!  no problem.  DAC works with USB from the computer.

So immediate problem is solved - at least i know the DAC works.

And more confirmation that my phone is a piece of crap, but oh well, got what i paid for.
