Hi again,
I'm now trying to record audio on the raspberry Pi B+ 512 MB.
The same code is running on Windows 10 and it works (I can record audio and playback it afterwards).
Now I'm not sure what I'm doing wrong.
I'm using the ACMFORMAT-Class for the Encoding and the call of the Constructor throws an Exception.
For recording I plugged in an USB Soundcard with an standard mic plugged into that.
The Bass-DeviceInfo differs between Windows 10 and Linux.
So I don't know if the device itself is the problem or the using of the ACMFORMAT.
Thank you!!!
Martin
