Thanks, was hoping to fix issues via USB with the likes of Hiby RS2 Sony Walkman and others that don't seem to work, waiting to hear from them
You can find a Windows PC and upgrade Erco's firmware, then you can try with those devices again. May be it can fix your problem but I am not hopeful.
Because in my case, it solved my problem on PC usage (as firmware update was for that reason) but it did not help problems with cell phone usage.
On USB Audio Player and Tidal's own app on the smartphone.
Actually I am not making this a big problem because I am aware of that Erco is not (yet) optimized for smartphone or DAP usage. And also UAPP app doesn't have full support for Erco.
Can I ask what kind of problem(s) you have with those devices?
In my case, when I connect Erco to my cell phone it's being detected as external device and it's being used as a soundcard for applications.
I am using on Tidal app and on UAPP (Tidal again through UAPP).
When I play my first track from my Tidal list and then let Erco to play next tracks automatically it plays very well with no issues.
But while playing a track if I decide to play another track, then it's not working properly.
One issue is that the led starts to go crazy (as it's not able to detect what sample rate is being played), another issue is that sound is being digitalized or distorted, another issue is music starts to play as in 2x speed.
So if Ferrum cooperates with Android developers may be all those problems can disappear. But until they solve that, I will play first track from my album or playlist and not change the track lol
