we experience problems using VoiceMeeter Potato 3.0.2.8 64bit together
with Marian Clara E, a Dante PCIe board (https://www.marian.de/products-archive/clara-e/).
Our Scenario is as follows:
Application with WDM Audio -> VoiceMeeter Input (7.1, 24bit, 48kHz) --> Marian Clara E ASIO --> Dante.
We map up to 3x7.1 VAIO input devices to 3x8 ASIO channels (A1, A2, A3).
The above setup works for Dante VirtualSoundcard (32x32 channels, using 24) and Dante AVIO USB (2 channels, using 2) but
it does not work with the Clara E ASIO interface. If we use the ASIO interface of Clara E, VoiceMeeter does not connect
to the card:
- 'HARDWARE OUT' only shows a blinking 'Clara E',
- 'A1' disconnects 'ASIO: Clara E',
- In 'Menu->System settings' the string 'Status: OFF SR:48000Hz buf:32' in the line "OUT A1 Main Device: Status: OFF SR:48000Hz buf:32 ch64 r:24' is red,
- resetting audio engine and the like will not work,
- changing the 'buffer sizes' may (or may not) change the STATUS to ON if we stay in the settings dialog.
We once managed to get the STATUS to ON for a longer time, after we set the (ASIO) sample buffer to 'buf:16'. But then we had no sound output.
Note: If we use a Clara E WDM Multichannel Device (32 channels), we can map 8 channels and get sound output
using Dante VIA as audio endpoint, but we need more channels, at least 24! That being said, the Clara E can deliver
512 Dante channels for each of its two ports.
Searching the forum, we found 'VB-Audio ASIO Test'. The Clara E ASIO interface seems to work OK with this
tools. We can hear the output of the test sound generators through Dante VIA, if the sample buffer size is larger than
16. Here is an abbreviated output of 'VB-Audio ASIO Test 64Bits (Version 1.0.1.3)':
#0001 ------------------------------------------------------

From this output we conclude, that the ASIO interface of the Clara E works in some
way. Maybe VoiceMeeter cannot handle the number of channels provided by the Clara E?
We appreciate any hints on getting VoiceMeeter to work with the card.
