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.

Not trying to be a smart ass here but when you hit play on your phone Spotify app, does it actually play anything and if it does did you try raising the volume on your phone? Sometimes the volume defaults to zero. 
Also check Spotify settings make sure you’re outputting either mp3 or redbook (16/44). 

@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.

try playing youtube or pandora on your phone thru the smsl and see if it works. if so, try uninstalling and reinstalling spotify.

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.
