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.

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.

@rop45 Congrats man. My advice — Apple’s introducing their iPhone 14, and after that arrives go to their website and search for a unlocked, refurbed iPhone 11 that’s a great phone and you can probably get at a huge discount now that it’s a few generations old. I’ve bought all my family’s iPhones and iPads this way over the past 8 years or so and they’ve all arrived as new and have worked perfectly, and I’ve saved thousands of $$$. I’m still using an iPhone 6 I bought this way and still works fine, but I’ll likely now upgrade to a refurbed 11 for the larger screen and faster processor for about what I paid for the iPhone 6 many years ago. Just my $0.02 FWIW.

There may be something in the Spotify Connect app that isn’t allowing it to play into your DAC. Products advertise if they are compatible with Spotify Connect. Hegel probably is, thus everything works there, but your external DAC may not. So the problem may be with the expensive DAC and not the cheapo phone.  Investigate if your DAC advertises Spotify Connect compatibility.  If it doesn’t, than it probably isn’t
