thanks, the problem is that by pressing the three keys the lights are not blue remain at the volume originally left, so it does not go in line out.

Are you pressing them from Mojo power off state? Mojo must be powered off, then press both volume buttons and hold down, then press power on while still holding down the volume buttons.

What iOS player are you using actually with Mojo?

 

[cirodts]

Usato wd tv live

 

[Mython]

Are you sure the TV isn't automatically upsampling everything to a high sample rate?

(credit to RiseFall123, as I'm guessing this was why the question was asked)


It may not be; it's just that sometimes people get a bit confused with the colour buttons and what they represent.

Some devices try to upsample all files, automatically, instead of respecting the original bitrate. For example, Android devices like to upsample everything to 24bit/192khz, which is why it is necessary to use an app like USB Audio Player Pro ('UAPP') or Hiby, to bypass the upsampling.


Your situation is a bit confusing, because yesterday you said:

hello, for now I'm using a lg v20 with player hiby. the result mojo exceptional, the mojo is just a magic box.

and now you are saying you are using:

Usato wd tv live

 

[cirodts]

Hi, I use the mojo with the v20 with excellent results and I use it with wd tv live in optic at the mojo and pei in the amplifier with modest results.

 

[cirodts]

is it true that the mojo makes the maximum usb output?

 

[491326]

what apps do you guys use on Android? I've been using neutron mp but it's not playing with the mojo nicely, with frequent errors that require restarting the phone which for some reason, sometimes doesn't work. what app works best? I have dsds too

edit: i downloaded uapp but it keeps giving me error starting playback

 

[cirodts]

hiby

 

[491326]

hiby

thx, hiby is playing but theres clicks on dsd files, do you know how to solve that?

 

[cirodts]

hello, I also noticed annoying clik before the song.

Some apps lose the first half second of a track, and this has been described in post #3

Some apps cause issues when the sampling rate of a new track, differs from the previous track.
Mojo is unaware of this change, and receives data that has a different sampling rate to what it was expecting.
Rather than play electronic noise, the Mojo is coded to mute the output, whilst it adjusts to the new sampling rate.

But after 100 hours of burn-in the mojo improves or are just nuances?

I don't believe in "burn-in". Very especially on a DAC vs. on a speaker. Placebo at its best. But you could ask the same question in the Sound & Science forum and see what they come up with:
