Ok, I will ask Charlie


@jiiteepee: But if it is processed in series, wouldn't the first delay also delay the second channel (and therefor not get rid of the problem)?

Depends on where you add this correction buffer (delay) ... I suppose VB does it "the right way".

Will the occurring delay be displayed, or do I have to adjust the delay by hand until it sounds right?


Up to this point the Windows + Banana + EPO solution sounds like the way to go.

(Running Ubuntu here) Probably by ear but, if you play same frequency sine wave through two devices simultaenously it's quite easy to hear when those are in sync.

I've never done it before, but that sounds quiet promising, thank you

Funny to find this thread are. I have a similar predicament. I want high-end DAC performance but with more than 2 channels. Most multi-channel DACs use 'meh' chips.

I tested the Voicemeter Banana option with an ASUS Xonar DX running the satellites and using a Focusrite Scarlett 2i2 for the subwoofers. In my quick test it worked ok. My main caveat was that the volume keys only change the main soundcard volume by default.

Solution is to use the MacroButtons feature of Voicemeter.

I've ordered a Topping D10 DAC which looks very promising for the money. Sadly for OP it's only stereo.

Why not use HDMI (8 Channel) and on board soundcard (6 Channel) at the same time. I did not try but I think there is a solution in Linux. Maybe with Pulseaudio or plain ALSA.

For HDMI and X-over take a look here. X-over realized by Laptop, Open Source and 7.1 AV Receiver over Display Port / HDMI

P.S.: After short Google take a look here for example Linux & Sound aus mehreren Soundkarten gleichzeitig | Coders Kitchen

I found this theme interesting so I dig a little in web.
ALSA_OUT seems to be a good solution and I gave it try.
I tested it on my second desktop. Not my main DAW.

In KXStudio its only one or two simple lines to add it to the jack configuration.
Code:
"alsa_out -j NVIDIA1 -d hw:2,7 -r 44100 -c 2"
"alsa_out -j NVIDIA2 -d hw:2,3 -r 44100 -c 2"

I have the following hardware interfaces
Intel Analog
Intel Digital (ALC898)
Intel HDMI with 3 subdevices
NVIDIA HDMI with 4 subdevices

I tried out in parallel
Intel Analog conected to a headphone (Hardware Playback in Cadence)
NVIDIA1 connected to a Monitor
NVIDIA2 connected to a UHD television

All in parallel are giving sound at the same time.

The sound is not 100% syncing.
Thats clear because each connection has its own DAC
Intel Analog by the inernal soundcard
NVIDIA1 by the DAC of the monitor
NVIDIA2 by the DAC of the UHD television.

Enclosed the connections shown in CLAUDIA.

So in KXStudio it is not a problem to connenct to all souddevices of your hardware together.

This is also with X-over and other plugins.

Work has to be done is to sync the sound to all devices.
But this also should be possible with the right LVS or LADASP plugin.

Guenter
