[12.0.0+] If [[Settings_services#BluetoothDevicesSettings|TrustedServices]] is 0, value 0x100000 is used. When bit20 is set, HID is initialized for this device, otherwise when bitmask 0xC0000 is set (<code>if((TrustedServices & 0xC0000) != 0)</code>) [[#OpenAudioConnection|audio]] is initialized for this device.

This is essentially the same as the other [12.0.0+] Get*EventInfo cmds, however in this case the output type is set to value 0 when no event is available.

Takes an input u32 [[#OpenAudioOut|audio_handle]], a [[#PcmParameter]], a nn::TimeSpan, returns an output nn::TimeSpan and u64.
Takes an input u32 [[#OpenAudioOut|audio_handle]], a [[#PcmParameter]], a nn::TimeSpan latency, returns an output nn::TimeSpan latency and u64.
This eventually uses BSA to start an AV stream. The codec is "Raw PCM". Synchronous feeding mode is used.

Takes an input u32, returns an output Event handle.
Takes an input u32 [[#OpenAudioOut|audio_handle]], returns an output Event handle.
sdknso uses an user-specified EventClearMode.

Takes an input u32, a type-0x9 input buffer, returns an output u64.
Takes an input u32 [[#OpenAudioOut|audio_handle]], a type-0x9 input buffer, returns an output u64 transferred_size.
This eventually uses BSA to send the specified buffer to the required UIPC channel. If transferred_size doesn't match the buffer size, error 0x177A71 is returned. transferred_size is always either 0 (error occured) or the buffer size.

Takes a type-0xA output buffer containing an array of [[#AudioControlButtonState]], returns an output s32.
Takes a type-0xA output buffer containing an array of [[#AudioControlButtonState]], returns an output s32 total_out.
A maximum of 0xF entries can be returned.
