Hi I've been running reaper through wine happily for quite some time now with kernel from liquorix, wine-rt + wineasio from kxstudio. I'm recording 24 tracks from my soundcraft mtk22 connected with usb to the linux box. After upgrading from debian wheezy to stretch I only have sound from channel 21, 22, 23 and 24 from the mixer (caputure_21 - capture_24 in qjackctl), the first 20 channels are dead silent. I tried with a new .wine folder, registering wineasio anew, and setting number of channels in wineasio to 24 in og 22 out as described in this post: http://linux-audio.4202.n7.nabble.com/Only-6-channels-with-wineasio-td10057… Besides the missing audio on channel 1-20 everything works great. Obviously the problem can be lots of places, but any pointers as to where to start looking would be highly appreciated.
