Version 1.1.0 (2016-01-31)

  • JACK: delete broken pause implementation. Previously, calling soundio_outstream_pause or soundio_instream_pause during the write_callback or read_callback would cause a deadlock. Now, attempting to pause always results in SoundIoErrorBackendIncompatible.
  • PulseAudio: improve latency handling code. It now passes the latency test along with all the other backends.
  • PulseAudio: fix incorrect outstream software_latency.
  • libsoundio source code is now pure C, no C++ mixed in.
  • ALSA: better device detection.
    • No longer suppress sysdefault.
    • If default and sysdefault are missing, use the first device as the default device.
  • Workaround for Raspberry Pi driver that incorrectly reports itself as Output when it is actually Input.
  • ALSA: let alsa lib choose period settings. Fixes behavior with many ALSA devices.
  • ALSA: fix potential cleanup deadlock.
  • ALSA: fix crash for devices with null description, thanks to Charles Lehner.
  • CoreAudio: drop support for MacOS 10.9. There was a bug for this system that was never resolved, so it didn't work in the first place.
  • Record example handles device not found and probe errors gracefully.
  • Fix typo in microphone example, thanks to James Dyson.
  • Improve documentation.
  • New functions available: soundio_version_string, soundio_version_major, soundio_version_minor, soundio_version_patch.
  • libsoundio source code now builds with MSVC, thanks to Raphaël Londeix.

Version 1.0.3 (2015-10-20)

  • Architecture independent header files.
  • Add --latency and --sample-rate to sine example.
  • ALSA: fix deadlock under some circumstances.
  • dummy: fix deadlock when pause called from write_callback.
  • Fix double clean-up corruption when opening stream fails.
  • Add --device and --raw to underflow test.
  • ALSA: use period size to calculate buffer size, fixes opening output stream sometimes resulting in an error.

Version 1.0.2 (2015-09-24)

  • build: fix GNUInstallDirs not working.
  • docs: fix incorrect docs for soundio_instream_pause.
  • PulseAudio: fix soundio_outstream_pause triggering assertion when called from within write_callback.
  • fix mirrored memory not working on Linux (fixes corrupted data in ring buffer).
  • os: fix crash when creating non high priority thread fails.
  • docs: fix typos and cleanup.
  • fix and add test for soundio_device_nearest_sample_rate.

Version 1.0.1 (2015-09-11)

  • libsoundio no longer depends on or links against libm.
  • ALSA: treat ALSA as unavailable when /dev/snd does not exist.
  • ALSA: remove duplicate assert.
  • ALSA: remove stray print statement.
  • ALSA: pausing returns error code when state is invalid instead of reaching assertion failure in pcm.c.
  • JACK: fix infinite loop when refreshing devices.
  • PulseAudio: better clear buffer implementation.
  • dummy backend: fix sometimes calling write_callback with frame_count_max equal to 0.
  • os: fix some variables accidentally not declared static.
  • macos: fix not cleaning up condition variables.
  • macos: avoid allocation when getting time.
  • docs: note that read_callback and write_callback must be real time safe.
  • docs: record example demonstrates proper real time safety by not calling fwrite in read_callback.
  • docs: add note to record example about shutting down.
  • docs: make microphone example latency a command line argument.
  • build: fix build on linux with clang.
  • build: static libs, examples, and tests are optional.

Version 1.0.0 (2015-09-03)

  • Initial public release.
