输入：
ai=analoginput('winsound');
out=daqhwinfo(ai)
输出：
out =

AdaptorName: 'winsound'
Bits: 16
Coupling: {'AC Coupled'}
DeviceName: '?'
DifferentialIDs: []
Gains: []
ID: '0'
InputRanges: [-1 1]
MaxSampleRate: 96000
MinSampleRate: 5000
NativeDataType: 'int16'
Polarity: {'Bipolar'}
SampleType: 'SimultaneousSample'
SingleEndedIDs: [1 2]
SubsystemType: 'AnalogInput'
TotalChannels: 2
VendorDriverDescription: 'Windows Multimedia Driver'
VendorDriverVersion: '6.0'

还有一段程序：
ai=analoginput('winsound

AdaptorName: 'winsound'
Bits: 16
Coupling: {'AC Coupled'}
DeviceName: 'Realtek HD Audio Input'
DifferentialIDs: []
Gains: []
ID: '0'
InputRanges: [-1 1]
MaxSampleRate: 44100
MinSampleRate: 8000
NativeDataType: 'int16'
Polarity: {'Bipolar'}
SampleType: 'SimultaneousSample'
SingleEndedIDs: [1 2]
SubsystemType: 'AnalogInput'
TotalChannels: 2
VendorDriverDescription: 'Windows Multimedia Driver'
VendorDriverVersion: '5.10'

我这里的输出，程序没问题，你声卡不能识别
我也不是很清楚，大概你的声卡驱动有些问题
