Hi
@iFi audio and readers all.
I just purchased a new Hip DAC to use with Tidal lossless on my Samsung Galaxy S20 Ultra 5G (and any future phone I upgrade to). Apart from being annoyed that I selected the original model when I meant to purchase the model 2 (100% my own fault) I am happy and impressed with this little beauty (I don't use MQA anyway). It replaced my Topping NX4 DSD which had a dodgy micro-USB port (which I broke altogether trying to fix it). This was a known quality problem with that model Topping, so I wasn't about to buy their product again. I have to say the build quality on the iFi is worlds better and the sound ot puts out into my aging well Oppo PM3 headphones, is equally good, and somewhat less fatiguing as my previous DAC.
I have one problem with it, the cause of which I suspect may lie with Samsung, but all the same, I did not have this issue with the Topping. This is that when playing Audo with HD USB capture on with either the Tidal app, or USB Audio Player Pro playback pauses randomly once the screen is off. Sometimes it will do it repeatedly like after only 10 -30 seconds, but at other times I may get 30 minutes uninterrupted play until it occurs: there is no rhyme or reason to it that I can figure out.
When it happens, I have to wake the device (either pressing the power button, or double tapping my screen (I have DD2W active) and play resumes from where on the track it stopped.
I have ensured both Tidal and USB Audio Player Pro are exempt from battery optimization putting them to sleep in the background, and the apps do not actually turn off. It is simply that playback is paused until I hit the power button again, when it resumes from precisely the point in the track where it had paused at.
It should never do this, and just keep playing until I stop it.
With the Tidal app I can ignore the prompt to allow HD USB capture and it will play through the DAC anyway, but you can hear the huge loss of audio quality with the Android downsampling this does, so that defeats the purpose of having a decent DAC.
Any suggestions appreciated
