Subject: Fix signed/unsigned mismatch (wmme device ids are unsigned) and improve semantics... 
X-Git-Url: https://andrewgundersen.net/repos?a=commitdiff_plain;h=0b3bd90badc55242ceca45d83e09c79400890d64;p=portaudio

Fix signed/unsigned mismatch (wmme device ids are unsigned) and improve semantics by explicitly setting the fallback default device to WAVE_MAPPER (which has value -1).
