Version 0.8.6:
|
|
- Added four methods to the 'PCM' class to allow users to get detailed information about the device:
|
|
|
|
- 'getformats()' returns a dictionary of name / value pairs, one for each of the card's
|
|
supported formats - e.g. '{"U8": 1, "S16_LE": 2}',
|
|
- 'getchannels()' returns a list of the supported channel numbers, e.g. '[1, 2]',
|
|
- 'getrates()' returns supported sample rates for the device, e.g. '[48000]',
|
|
- 'getratebounds()' returns the device's official minimum and maximum supported
|
|
sample rates as a tuple, e.g. '(4000, 48000)'.

Version 0.8.2:
|
|
- fix #3 (we cannot get the revision from git for pip installs)
|
|
|
|
Version 0.8.1:
|
|
- document changes (this file)
|
|
|
|
Version 0.8:
|
|
- 'PCM()' has new 'device' and 'cardindex' keyword arguments.
|
|
|
|
The keyword 'device' allows to select virtual devices, 'cardindex' can be
|
|
used to select hardware cards by index (as with 'mixers()' and 'Mixer()').
|
|
|
|
The 'card' keyword argument is still supported, but deprecated.
|
|
|
|
The reason for this change is that the 'card' keyword argument guessed
|
|
a device name from the card name, but this only works sometimes, and breaks
|
|
opening virtual devices.
|
|
|
|
- new function 'pcms()' to list available PCM devices.
|
|
|
|
- mixers() and Mixer() take an additional 'device' keyword argument.
|
|
This allows to list or open virtual devices.
|
|
|
|
- The default behaviour of Mixer() without any arguments has changed.
|
|
Now Mixer() will try to open the 'default' Mixer instead of the Mixer
|
|
that is associated with card 0.
|
|
|
|
- fix a memory leak under Python 3.x
|
|
|
|
- some more memory leaks in error conditions fixed.
|
|
|
|
Version 0.7:
|
|
- fixed several memory leaks (patch 3372909), contributed by Erik Kulyk)
|
|
|
|
|
|
Version 0.6:
|
|
- mostly reverted patch 2594366: alsapcm_setup did not do complete error
|
|
checking for good reasons; some ALSA functions in alsapcm_setup may fail without
|
|
rendering the device unusable
|
|
|
|
|
|
Version 0.5:
|
|
- applied patch 2777035: Fixed setrec method in alsaaudio.c
|
|
This included a mixertest with more features
|
|
- fixed/applied patch 2594366: alsapcm_setup does not do any error checking
|
|
|
|
|
|
Version 0.4:
|
|
- API changes: mixers() and Mixer() now take a card index instead of a
|
|
card name as optional parameter.
|
|
- Support for Python 3.0
|
|
- Documentation converted to reStructuredText; use Sphinx instead of LaTeX.
|
|
- added cards()
|
|
- added PCM.close()
|
|
- added Mixer.close()
|
|
- added mixer.getenum()
|
|
