Great stuff..will try...so far on my list:

- Micro Linux (just posted)
- Arch Botic
- LightMPD
- Build your own with Fred's instruction
- Same, but with DietPi
- TW_Luke's revised Kernel

I am not a Linux guy at all, but used MPDpuppy now for many years on an Alix1D board...so I am a believer in light-weight solutions, enabling ideally as well underclocking (not sure if the beaglebone has that option)

MPD will probably need Hermes/Cronus powered and attached. Damage to the BBG can occur if power is removed while there is voltage on the GPIO pins. If you always use the ‘shutdown’ command you should be OK.

Next version mini Botic7 firmware
http://puredsd.ru/buildroot/sd_botic7.img.gz
  • Change: small changes webinterface
  • Fix: MPD can now play DSD256 and DSD512

The firmware was created primarily for PPY's ReClocker and new version DSC2.
But it can be used as a universal network transport for PCM/DSD and with other equipment. It is enough to do the configuration in the file /boot/uEnv.txt

SSH root/root

And buildroot for this firmware:

Update: GitHub - coroner21/linux-am33xbot: Arch Linux ARM Kernel with botic patches is now up to date with linux version 5.15. Note that for all three codec drivers (ES9018K2M, ES9018, Botic dummy-codec) I now enabled DSD_U32 again, which means that at least DSD256 is supported.

Background is that the MPD bug causing distortions in case of DSD_U32 playback was fixed in MPD version 0.21.11.

In my version of MPD, it works as a UPNP renderer.
MPD does not have the ability to connect directly to the music database. This is done intentionally.

You can do this without any problems using the BubbleUPnP program.
Tidal -> BubbleUPnP -> UPNP renderer
or
Roon+Tidal -> Roon Bridge

Thank you for the explanation!
As far as I understand the best way for my needs (playing m3u playlist files) I should use Debian BUSTER or ARCH LINUX with Botic Driver and necessary packages.
MPD ->UPNP renderer> BubbleUPnP

Funny moderation experience...not sure why stuff got deleted.

ppy, coming back how to make the mpd renderer function works...any server suggestion ? I guess this is how it works generally, no ? An UPnP Audio Media Renderer based on MPD

I am using BBb, chronus, hermes to drive B3, Soekris DAC...amd later maybe compare this with DSCv2...its great that you build an image that is so universally usable.

I usually listen to Roon and HQPlayer.
I checked UPNP with Jriver. It is convenient, it is both a server and a controlpoint. But you can use any DLNA server. A good, free and functional server - MinimServer
You have correctly indicated the UPNP MPD operation scheme. An additional front-end is used - upmpdcli.
