Howdy.

Not sure if you've seen it. pCP6.0 has been released.

Now, since March 7th, you've got full RPi4 support with 64bit kernel and also realtime kernel.
Unfortunately userland is still 32bit - and probably that won't change.

As far as I see, the pCP folks have also taken care of the firmware/eeprom handling.
Which is nice.

I'd strongly advise to give pCP6.0 a try.

You should also try to make use of the LogitechMedia server on pCP6.0-Pi4.
I'm running a Pi4 as server with SSD attached.
Works great since months. I do not use the rt-kernel on the server though. Just the client runs it.
If you do try the server setup, make sure you isolate CPU0 and switch to performance governor
to avoid data loss or mediocre network performance if running GBit ethernet.

Enjoy.

If you are running PcP, I'd also suggest using the Material skin, for control of all connected players.

Yep. I'm running it too. That puts LMS/squeezelite based solutions on a new level.

How big is your audio collection, Soundcheck? Can Pi4 in this configuration handle big audio collections, e.g. 1,5TB of flacs?

Yes. No problem.

Scanning takes a bit longer compared to my i5 NUC.
IMO more than acceptable though. 10k tracks take around 1.30min on the Pi4.
You can extrapolate that.

With wired GBIT Lan I do not notice any annoying lags on my UIs .
Otherwise a Pi-as-server setup would have been a NoGo.

SSD is highly recommened. It's fast. low power and you don't see these
power surges that you'd face with a HDD attached.

That than allows to use just 1PS.

Hint: Make sure you get yourself a USB3-Sata adapter that supports "trim".
Not all of them do!


And. Running heavy DSP on a PI, even a Pi4, is still something I wouldn't do.

And finally - don't forget to get yourself a quality passive cooling case!

Enjoy.

Approx 1,000 CDs, (1 TB - 10,000 tracks) in WAV/CUE format takes me roughly 5 minutes to scan into database on RPi4B with USB HDD. It looks like the format can effect the scan times as well as SSD vs HDD.

All user interfaces that I use, have no lag even over 2.4 wifi.

Because piCorePlayer is extremely small, I can build a pCP squeezelite player in 5 minutes and a my pCP LMS server in 15 to 20 minutes from scratch. I have had lots of practice though.

BTW: I agree the Material skin is a great addition to the Squeeze/LMS environment.

So 1x LogitechMedia server on pCP6.0-Pi4 with 2TB USB>SATA SSD + 1-2x pCP6.0-Pi4 with Khadas TB as clients should be Ok? Any recommendation for GUI SW while controlling from Win PCs?

I'd separate clients from servers. However. Running both on one machine also works.
I'd avoid at least a shared data and audio USB setup. Of course this would also work.
And there'd be no way I'd be running a server over Wifi, but yep, it'd also work under certain conditions.

As user interface the excellent "Material Skin" plugin, can be enabled during LMS installation from the LMS-Plugin settings menu. MSkin should work on any browser and therefore any OS ( I havn't tested all of them ).
Once enabled you access the UI via " 192.xxx.x.xxx:9000/material" and that address you bookmark. MSkin comes with mobile and desktop layouts. For easy access I added shortcuts to my homescreens (Android) by using the "bookmark add to homescreen function" that you find in the browser menus.

Let's leave the thread for Pi4 related stuff. Pi4 as LMS server should be discussed elsewhere.

Enjoy.

As well as using Material skin on any browser, there is also Squeezelite-X, available in the Microsoft Store for Windows 10.

You can run the Material skin on Squeezelite-X...
