Access/Modification of the static OSS_OpenFD isn't thread safe, so when OSS_OpenDevice() fails, the -1 is stuffed into OSS_OpenFD, which hoses the playback thread. If I make the necessary changes to make the OSS_OpenDevice() failure not blast OSS_OpenFD, the playing thread eventually does finish. All the while, the other thread keeps tring the open again and again.... Ultimately,...
