I see now that on BBB there is a chip called TPS65217C that takes care of charging an external battery. So Hermes only provides a connection for this.

Hi,
I have some trouble playing dsd files with bbb/ Hermes/Cronus (45/49 clocks)
Playing pcm at 384 kHz gives stable lock at dpll setting lowest.
But dsd 64 has every 1-2 seconds no lock. DSD 128 even more unlocks and intermittent hissing sound. Only if I set dpll to highest I get stable lock.
Thought was problem with teleporters I use. But also with direct connection via short uFl cable problem is the same. Checked al power rails while playing Musik and everything is ok.
Any advise? How much is impact of dpll settings?

It will be a while.
Silicon Labs sold a chunk of its business to Skyworks last year, including the isolators we use, and they are now unavailable until later this year. I have been mulling a redesign to use Analog Devices components, but have not had the time due to moving to a new house and such.
