Attached the screen. Although the screen works (my wife loves the matrix kinda nerdiness) the Ropieee doesn’t seem to recognize it: the display tab is missing in the web page.

124

I am not sure adding a screen to an existing build will be plug and play. You may need to re-install Ropieee for the screen to be picked up and accounted for.

125

Good call. Reflashing it now.

OK, I’ve got a Display tab now. In Roon it’s recognized as Extension. Still, it doesn’t seem to work.

126

So
 are you running this with the beta? As mentioned, the beta is not tested on the display (yet).

And what do you mean with ‘doesn’t seem to work’? What do you see on the screen?

127

Yeah, running the beta in an attempt to test it for you. :slight_smile:

Apologies for the bad testing report, haha. I see a black screen telling me Ropieee is running.

128

hehe ok clear.

It sounds like the graphics drivers are not running.
I’ll add it to the list to test.

If I need to log into ssh to check some things, or grab some logs, let me know.

Two advantages come to mind:

  1. As already mentioned, the RPi4 design vastly improves its native USB hardware configuration. This has the potential to eliminate the need for a USB HAT for most users wanting USB connectivity to a DAC.
  2. The RPi4 natively supports 5GHz Wi-Fi. (You could get this on the 3B+ as well, but most people using an RPi for a streamer were using the base 3B model.) Using 5GHz will dramatically improve Wi-Fi behavior, since the 2.4GHz range is so oversaturated these days it’s basically useless for anyone living in a dense urban environment.

Can you send me feedback? You can find it on the advanced tab of the webinterface.
Just drop the uuid over here and I can have a look.

132

Just sent the feedback ( 2083b4115365bac9)

133

What’s the UUID?

Btw, it just added an error on the screen while I was playing:

ERROR: transfer event for disabled endpoint slot 2 ep 3 (long code follows)

DAC is connected to one of the USB2 ports

135

Is that the case? I think I read somewhere that it’s not that obvious, that 2.4 goes further (penetrates walls better due to wavelength) and that it depends what else is being used, so maybe noT?

136

Yes, it’s really the case. Unless you live in the middle of BUFU nowhere, 2.4GHz is oversaturated and largely unusable. That “travels father” is part of the problem, too. Since consumer Wi-Fi access points all operate at 100% transmit, even when they don’t need it, you get lots of spectrum bleed. The extra distance doesn’t actually amount to that much in real world usage, as you have to get signal back as well. You get maybe an extra 20-50 feet. But one way, that signal interferes with other users of the spectrum. 5GHz has so much more spectrum available, that you get much less overall congestion and devices can speak without getting stomped on. If you need to cover a large house, the proper way to do that is with multiple access points, not trying to shout really loud with a single one. Throughput is terrible in the latter case.

Where I live, 60% of the 2.4GHz duty cycle is consumed by Wi-Fi management beacons alone. That’s not even real data getting passed around. It’s all the APs of my surrounding neighbors shouting out “I’m here! I’m here!”. (I see ~50 live SSIDs if I open a Wi-Fi scanner.) My 2.4GHz-only devices constantly get knocked off the network and have to reconnect. Meanwhile, the TOTAL used duty cycle in the 5GHz spectrum averages only 3-5% and devices have no trouble staying connected and transferring data at high speeds. On 2.4GHz, you’d be lucky to sustain 5-7Mbit/s real world transfer rates in my place. Even with 802.11n.

Any new device that is 2.4GHz-only is defective by design

@RBM can you rename this thread? To something like

New Raspberry Pi 4 on RoPieee

or something? I see the thread get’s confused by a more generic discussion.

Thanks,

138

Ok, pushed out an update in the beta channel.

Nothing fancy, just an update to the latest kernel (4.19.57), latest firmware and latest bootloader.

Still fighting the WiFi though. For some reason the chip refuses to initialize :frowning:

Running now. Nothing fancy happening. Still sounds good, still no fancy display (don’t worry, wasn’t expecting it yet)

@wizardofoz already did, I see. :+1:

Hello
Is it possible to use the HDMI output with the Ropieee installed and connect a monitor to it? Do you then have the image of the roon software. Played title and cover?
