I have two main concerns right now that I have to address.
The first is referred to my home setup, where the pi (+ digital out HAT) will be placed between a NAS (lan) and a DAC (digital coax). The control is a Iphone 5S and the music will be both in the NAS and streamed through Spotify by the smartphone.
Right now I’m testing the chain by using an usb pendrive with some music directly connected to the pi.
If I play music through Spotity all goes smooth, without any problem.
If I play music through the usb pendrive (after having mounted it in Volumio) I get some glitches and the program skips tracks at random.
I tried various usb pendrive and music but the problem is always there.
Someone have some idea? Should I expect the same problems even when I will have a NAS connected to the network ?
The second problem is referred to my car setup which I’m building right now.
I’d like to use my phone to stream music through Spotify to the raspberry and to open the music stored in a local HDD connected to the pi or as an alternative to stream the music from my home NAS by using a VPN connection (for safety purposes).
The problem is the following.
If I use the Hotspot function of my Iphone 5S the raspberry can connect to it, but then I can’t from the phone take the control of the pi because they are running on different networks (4G the iphone, wifi the pi).
Is there a way to solve this (maybe with a specific app or raspberry script) without having to buy a 4G dongle for the pi and having to use an extra SIM card with an extra internet plan?
Also does someone know a 12V~14,4V DC to 5V DC step down converter (or just a transformer instead?) which will be good to run the pi, without having to spend too much money?
Thank you guys
