[alsa-devel] [PATCH 0/4] ALSA: ctl: fix userspace control element operations

[Takashi Sakamoto]

This patchset is to fix some issues related to operations for userspace
control element. Three patches are related to identical information,
the other is related to several element added by one operation.

Unfortunately, current alsa-lib has no functionality to achieve the
operation to add several element. To demonstrate this and test these
patches, I prepare for a small GObject introspection library, alsa-gir.

This reposiroty includes sample scripts written by python. The file of
sample/ctl.py demonstrates userspace control elements.

If this library helps your review for this patchset, I'm feeling happy.

    elements
