I realize this was just announced ....

https://www.raspberrypi.org/products/raspberry-pi-4-model-b/

How about a sticky placeholder for any announcements regarding this new hardware?

Thanks

OK. We'll use this thread.

We'll get one as soon as possible, but my guess is that everything will just work.

Ships July 19th.

Changes:
High-performance 64-bit quad-core processor
Available with 1GB, 2GB, or 4GB ($35, $45, and $55 for bare board)
Supports two 4k monitors
Has 2 USB 3.0 and 2 USB 2.0 ports

Might not be as straightforward as previous Pi upgrades. They switched from Cortex-A53 to Cortex-A72. Per tomshardware:

To run Pi 4, you’ll need to download a brand new build of the Raspbian OS, Raspbian Buster. And not everything runs in Buster yet. During testing, we found numerous Python libraries or other required packages that weren’t compatible with the new OS.

Another issue is Raspbian is still 32-bit, even though arm64 should be doable.

That was the same on the Pi3, also had 64-bit cores. They don't seem to see the value to be high enough to warrant the effort.

In any case, options with more memory finally being available is quite nice. 1GB memory was one of the biggest Pi bottlenecks. In addition, the CPU should be decently faster, and we'll see if the GPU is finally usable.
The IO also seems to have gotten a much needed upgrade.

Hi everyone,

been using JRiver 25 in Raspberry Pi 4 with raspbian (debian buster). Haven't tried much but the experience has been great so far, no problems whatsoever playing different music files of high res audio (flac and DSD) with a ifi nano iDSD LE dac connected to the pi.
I did find a bug in the tagging process though (everytime I type a letter it selects the whole tag).
But the real novelty for me is that:
THEATER VIEW is now USABLE!!

PS: I hope the JRiver dev team pays attention to this and continue to make improvemets regarding theater view performance on the lastest pi

That's... pretty major actually. Hendrik should be happy to hear that it's finally usable on a Raspberry Pi.

As far as I know, it wasn't a performance optimization issue or anything like that at all. It's just the Raspberry Pi's GPU was simply not powerful enough to handle theater view. Let's hope the Raspberry Pi 4 has indeed changed that for the better.

This should be fixed in 25.0.71.

Anyone try Pi 4 converting DSD multichannel to 2 channel Flac?

Also - just more general question.
I'm assuming that JRiver's performance will benefit from 4gb over lower amounts ?

JimH · « **Reply #10 on:** July 02, 2019, 09:56:49 am »

~~The Pi 4 won't be available until July 19th or so.~~
Micro Center had some this weekend. We got two 2GB models today. Definitely faster.

Performance should be improved, in general. 2GB should be enough.

bob · « **Reply #11 on:** July 02, 2019, 03:33:06 pm »

Just got a couple of the 2GB models today.

A bench is here:
https://yabb.jriver.com/interact/index.php/topic,54396.msg838779.html#msg838779

They are about twice as fast as a 3B+ for our use and OpenGL works properly on them now so that Theater View works fine.

Using the PI4 is looking very good for me.

Setup:
PI3(OpenMediaVault for file serving) -> PI4 (MC install) -> Parasound HINT USB dac or Gizmo on tablet or OPPO 205

Parasound:
USB DAC is selectable playback device
2 Channel DSD plays (bit) perfectly
6 Channel DSD plays downmixed to 2 channel (slight delay for processing)

OPPO:
DLNA Streaming to my oppo 205 works perfectly (original format)

Gizmo:
Streaming to Gizmo with transcoding works (including multichannel DSD). Of course there's a little more delay going over wireless - but it's not bad

Looking really good.

Caveats are:
I haven't used this too long.
Stuff happens
Haven't tried streaming or playing to multiple devices at same time

But... a while back, I did try this on a RPI3 and it was not useable for any use case.

I'll let you know if I encounter any issues

BTW - Also have Logitech Media Server installed on the PI4 .... Haven't tried streaming from both servers at same time, but that's for another day.

I installed desktop version of latest from Raspberry site. Followed quick setup guide in this group.

Thanks!

One thing I noticed while using it to do compiles with all 4 cores, it will start thermal limiting within a minute or so when using just a passive heatsink.
Compiling MC was only about 10% faster than on a Pi3 until I added a small fan which prevented thermal limiting and nearly halved the compile time.

So, if you are going to be doing anything that uses all of the cores in anything other than a short burst you'll need to consider the cooling...

We have the IdPi4 working now. All orders for IdPi's will receive an Id that works with both the Pi4 and the older Pi3.

We're selling these at $33 (regularly $39) for a few weeks.

Yes.
You'd want to at least get the 2g version.

Anyone try MC on a Raspberry Pi with the Raspberry Pi official touchscreen?
