alsa-project/alsa-gobject pull request #15 was opened from takaswie:
This patchset is to add a new library, libalsahwdep, to operate ALSA hwdep character device.
ALSA hwdep interface is designed to execute driver-dependent code from user space application. Therefore there're a few common operations. Furthermore, some of the operations are just for ALSA snd-usb-usx2y driver for TASCAM US-122, US-224 and US-428, as of Linux kernel v5.6. The library doesn't support the device-dependent operations.
The library has 4 global APIS. ALSAHwdep.get_device_id_list() returns the list of numerical IDs of hwdep device in a card. ALSAHwdep.get_hwdep_sysname() and ALSAHwdep.get_hwdep_devnode() returns sysname and devnode for the card and hwdep device. ALSAHwdep.get_device_info() returns ALSAHwdep.DeviceInfo GObject-derived object which represents the information of hwdep device of the card. The object has some properties, one of which is a enumeration in ALSAHwdep.IfaceType to represent the type of hwdep device.
