[openal] Listing/accessing specific input channels

[violini]

Hello all,

Is there a way to list/access specific input channels on my soundcard? I’m using the latest openal-soft dll (1.18.2), and I’m using a Steinberg UR44 which is equipped with 6 analogue inputs. When I list the available devices using ALC_CAPTURE_DEVICE_SPECIFIER, I receive only  the following: "OpenAL Soft on Steinberg UR44”. This records successfully on channels 1 and 2. But how do I list/access the other 4 channels?. My ultimate aim is to open multiple instances of pALCDevice and record on all 6 channels. Many thanks in advance.
