Direzione di ricerca

Start by reading the CoreAudio output configuration code and its tests; the issue does not name specific files or test entry points. Reproduce device enumeration on macOS with a two-channel output set to 16-bit Integer, then compare it with 24-bit Integer. Done means enumeration handles the 16-bit case and reports the device’s sample format as expected.

Descrizione

host - coreaudio platform - macos

I'm getting the following errors when enumerating devices on OSX. Both failure cases are 2 ch outputs set for 16-bit Integer, as viewed via the Mac Audio MIDI Setup app. If I set one of the erring output devices to 24-bit Integer, the error is no longer reported for that output.

The USB audio CODEC device is a MXL ProCon Series 1 AC-404USB PZM mic.

Also I would expect the sample format to be preserved, instead of being promoted to a F32.
