[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, 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, no output.
+
Takes an input u32 [[#OpenAudioOut|audio_handle]], no output.
 +
 
 +
This eventually uses BSA to stop an AV stream. The pause flag is set to false.
    
== GetAudioOutState ==
 
== GetAudioOutState ==
−
Takes an input u32, returns an output [[#AudioOutState]].

−
Takes an input u32, returns an output [[#AudioCodec]].

−
Takes an input u32, returns an output [[#PcmParameter]].

−
Takes an input u32, returns an output Event handle.
+
Takes an input u32 [[#OpenAudioOut|audio_handle]], returns an output Event handle.

−
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.
