Hello Experts this crazy german Guy has an stupid idea and need Advise!
If i use 2 RPI 5 with same Software (Camilla DSP) and spread my 4 I2S Channels to them like on my Crazy Plan to use 2 MOTU UL at the same Time or even 2x 8 Channel DAC Sync on I2S Out form RPI 5 1 and 2 (at all 8 I2S Outs, 16 Analogue Channels) or Async USB (Topping DM7, MOTU...).
Any chance that this devices runs neare syncrone ???? They get his Input I2S Clocks at the same time and you could use one SPDIF out from MOTU 1 to Sync the Motu 2
Will this makes sense or may be a bit of sense???
would be realy nice if i could use something like 2x Topping D7 instead of one MOTU Ao24 or 16, Pricly a bit cheeper and even better specs i guess, dont need all the studio stuff on the Motu's
The Timedelay between The Channels could be corected with an Delay on Camilla , on surround settup you need to set the Delays for ech Speaker to be correct so anyway.
And if i want to listen Stereo i need only one RPI and can switch the other Chain off independant, (RPI 2+DAC Off)
Most time i listen Stereo so only for an Movie i need all Channels or for some Surround Music.
There is by sure an Time drift between two RPI's but how much coud it be???
2 USB DACS at the same time on one RPI5 with Camilla isnt' working right?
Found that:

1/4 ms timeshift betwen 2 same USB Dacs so not an good idea i guess ;(
The Problem is it seems not to be every time the same so you cant compensate it with fix Delay on Camilla per Channel
So better to use one 16 Channel Dac on one RPI at least.
