If i’am reading this correctly, 24bit is max bit depth supported by HDMI?
Other formats are optional, with HDMI allowing up to 8 channels of uncompressed audio at sample sizes of 16-bit, 20-bit and 24-bit, with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz
Looking good for 192KHz support on RPi HDMI, using our modified kernel:
We’ll get this completed for v143 update, and, also provide steps required here before its release, just in case our users wish to pre-test the 192KHz HDMI abilities.
Just had chance to try it - at the moment I am getting white noise when sample rate exceeds 44.1kHz. Certainly white noise at 96kHz and 192kHz. Will check others too and report back
UPDATE I don’t think the frequency is the issue it is the bit rate. I have a recording I made on a portable recorder 192kHz but 16 bit. That plays perfectly and the processor confirms 192kHz. All my other hi res recordings are 24 bit and none of those plays anything other than white noise with the music deep in the background.
UPDATE 2 Yes, I have now set the max bit rate in the Roon Playback configuration screen to be 16 bit so Roon now truncates the 24 bit data and the Hi Res music now plays albeit at 16 bit. So >16 bit is a problem with the Beta.
Not sure in this case: DietPi detects the Pi version at first boot. @Dan_Knight will be able to deliver the final verdict on this, but in the mean time it does not hurt to try.
My guess is that you will be OK (although you’ll miss out on all the fun of installing a fresh Pi on a Friday night… ;-)). You could clone the card with ApplePiBaker if you want to keep both Pi’s in service.

Will be fine to swap into RPi 3 from RPi 2. Device codes are detected during each boot.
I wouldn’t recommend changing from a RPi 2/3 to RPi 1, as CPU core count is reduced from 4 to 1. This applies mostly to webserver stacks and their thread count applied in dietpi-software.
1= When you boot the system or login to SSH. You’ll see the DietPi banner mention update is available.
2= You can run dietpi-update to check for updates.
Updating is not a requirement, but we do patch bugs and improvements to DietPi during the update. Ideally check the patch notes for anything that may benefit your setup.
For new users, I’d highly recommend creating a system backup once your system is setup how you like it. Simply run below and create a backup: dietpi-backup
