- Remove dead code
- Fix format selection and playback with raw devices
- Fix OSS backend
- Remove dead code
- Don't open the device in non-blocking mode. There is no error
handling for short writes and looking at how audio_play() is used in say.c
it is expected to block.
- Fix format selection
- Let the kernel handle sample conversion instead of doing it in the backend
- Make NAS support optional
- Make installing dictionary database tools optional
- Add LICENSE
