Hi, 

I read some posts having issues with power but I can't figure out what is the problem with my setup.

I have RPI 3B+, HiFiBerryOS 20201202, Amp2, Mean Well GST60A18-P1J  power adaptor. I'm using my phone to navigate HiFiBerryOS and  play radio/music. It works fine. Today I connect official 7 inch display which causes some issues:

1. when I moving volume slider on display, slider follows my finger but when I remove finger from display, volume slider goes back to previous position (I can not change volume).

2. Navigation through menu is slow, sometimes doesn't work (for example: when selecting Sources \ Radio and trying to go back, nothing happened) or takes some time.

3. When selecting radio station, going to  prev/next navigation sometimes doesn't work or takes some time, to show navigation page. Going back is worse.

4. When selecting radio station from first row I have to wait some time, to start playing. Selecting radio station from second row doesn't play selected station at all.

All scenarios works fine when I navigate HiFiBerryOS with my phone.

I also removed Amp2 and test the same scenarios but with no luck. The same results with 5V adapter.

Can someone help me?

Thanks.

  The web browser on the Pi is simply extremely slow. As long as there isn't a version that's a lot faster, there is nothing you can do.

  Hi,

  Don't quite understand. Web browser is the same, when I'm using my phone to control HiFiBerry? Because, controling HiFiBerry from my phone works ok.

  Would be RPI 4 2G fast enough to speed up web browser?

  It's not about the Pi, it's about the web browser. The one we're using on HiFiBerryOS just performs badly. As long as there isn't be a better one, it will stay like this.

  Hi. That's strange. Display is useless. I can not change volume, can not restart or shut down HiFiBerryOS, navigation is poor, sometimes I have to wait 10sec, sometimes doesn't work at all. I read that some people had problems with power supply but not that kind of issues that I have.

  Any solution?

  You can simply try an external power supply for the display.

  Hi.
  I already did.
  I tried with 5V adapter to supply display, RPI and Amp2 at the same time. 
  I tried with Mean Well GST60A18-P1J to supply display, RPI and Amp2 at the same time.
  Then I disconnect power jumper wires between display and RPI and tried to supply PRI and Amp2 with Mean Well GST60A18-P1J and separated 5V adapter to supply display.

  Unfortunately I got the same results.

  I tried the same scenarios on the same hardware with OSMC and didn't noticed any issues --> It seems that HW, wiring and power supply is OK.

  Sometimes I also get error which I didn't noticed before I connected display: 
  Crash!
  http://localhost/#now_playing
  The renderer process crashed. Reload the page may fix intermittent failures.

  Unfortunately I can not refresh page because there is no link. Scroll does nothing. But I can normally operate HiFiBerryOS from my phone while error is displayed. Solution is only to restart HiFiBerryOS from my phone.

  Any ideas?

  In this case, there is nothing you (and we) can do. We have to use the browser that's available. As long as there is no better browser available, we can't do anything.

  Also, available update (20201213) is not shown in official rpi display. But after checking for available update from my phone, update becomes visible on rpi display.

  Does anyone report or facing with similar problems?

  Solution is simple, but expensive.

  Use second PI4 with normal Raspbian OS installed running Chromium and display connected, to control hifiberry over web user interface. Increase your budget to ~60$. It can act as CD/DVD player as well as media sharing center too.
