annotate test/testpalette.c @ 3846:66fb40445587 SDL-ryan-multiple-audio-device

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Removed distinction between "available" and "init" in audio backends, since both had to be checked for success as a pair at the higher level and several of the Available methods were just always-succeed placeholders anyhow. Now the availability check is done in the init code, and the higher level tries all possible drivers until one manages to initialize successfully.
