1 month ago Devices on Windows with more than 8 ch are presented as multiple WDM devices with 8 ch each.
This is not determined by WDM, there is no 8 channel limit. The manufacturer has simply chosen to present the device like this. This is quite common (and also quite annoying). The Motu M4 for example is presented as two stereo devices.
Would it be possible to add a build option ASIO backend?
I understand that ASIO and GPLv3 licensing does not support distribution of a binary, but a self-build option would work for people who need it.
I had a brief search for Rust ASIO libraries, some seem reasonable.
ASIO has a number of problems in addition to the license. See for example here: https://www.diyaudio.com/community/threads/camilladsp-cross-platform-iir-and-fir-engine-for-crossovers-room-correction-etc.349818/post-6813205

There are supposedly ways to work around these problems but implementing a new backend is already a lot of work without having to deal with such stuff. The only asio binding I'm aware of is the low level asio-sys that is used in the CPAL library. I don't really have the time to implement and maintain an asio backend.
Then one reasonable path I see is to use the asio support of CPAL. This would be quite straightforward since CPAL is already used by the jack backend. Unfortunately this worked very poorly last time I tried it. I'm following the development there, but asio doesn't seem to be a priority so not much happens.

In contrast the ASIO driver presents the whole channel count.
For these devices, CamillaDSP can't be used on Windows.
