Not sure if this is the right sub-forum. I have an issue with the audio driver messing up every once in while. This is with the iCM4+. Here's the setup: A softsynth (let's say Animoog because it's rock solid) playing on my iPad, connected to the iCM4+ host jack 3; audio is being passed through to a Win10 laptop running Reaper and is received on a audio track there; there is another softsynth (let's say: Helm ) loaded in another track in Reaper; Reaper uses Asio4All aggregating (bridging) the iConnect audio driver as an input, and the ASIO driver from my Soundcraft desk as an output. All devices are set to run at 48k/24bits. The ASIO buffersizes of the individual drivers are all set to 256 samples in "safe" mode (that's way beyond the 64 samples the Soundcraft desk usually runs on). In the ASIO4ALL control panel though, the iConnect driver is set to 512. But whatever buffersize I use doesn't matter. When I start playing, I can play for half an hour without a glitch or a pop, and then all of a sudden the iPad sound heavily distorts (typical of a driver issue, losing the clock). It can go away by itself when I leave stuff idle for a while, or not.
-on the headphones of the iPad the Animoog sound remains perfect, so it's not the app.
-the Helm sound, running on the laptop, as heard on the mixer (via ASIO4All=>Soundcraft USB driver=> mixing desk) remains perfect as well, so it's not the Soundcraft driver
-restarting the Animoog doesnt help
-restarting Reaper, thus closing and re-opening the drivers on the Windows side does help.
-In Windows, system sounds are disabled; onboard audio is disabled; laptop running in "airplane" mode;
-I tried various buffersizes to no avail (took me a day because this happens every 15 minutes or so)
This is rather annoying, a showstopper indeed. I am really enthousiastic about this AudioThrough feature, some plugins sound really amazing when using the Souncraft converters.
What can I do to debug this? (I'm quite computer-savvy, I have coded a series of VST plugins in C++ myself (but not active anymore), don't hesitate to suggest the difficult stuff) My iPad sure is an old one, but on the headphones the Animoog (and the other plugins I tried out, I don't use many) runs fine (it was developed initially when my iPad was current).
