奇怪的错误-X11代理混合了声音问题

Question

“在Raspberry 3中播放基本声音文件时遇到问题。

错误消息是

$ sudo aplay buzzer.wav
PuTTY X11 proxy: wrong authentication protocol attempted 
xcb_connection_has_error() returned true
Playing WAVE 'buzzer.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

“ X11代理”与“游戏”有什么关系？

相似的结果，不同的命令：

$ sudo  aplay -l
**** List of PLAYBACK Hardware Devices ****
PuTTY X11 proxy: wrong authentication protocol attemptedxcb_connection_has_error() returned true
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]
Subdevices: 8/8
Subdevice #0: subdevice #0
Subdevice #1: subdevice #1
Subdevice #2: subdevice #2
Subdevice #3: subdevice #3
Subdevice #4: subdevice #4
Subdevice #5: subdevice #5

PuTTY X11 proxy: Unsupported Authorisation Protocol

    

  

现在“ X11代理...”错误消失了。

现在我只有

~ $ sudo  amixer cset numid=3  1
xcb_connection_has_error() returned true
numid=3,iface=MIXER,name='PCM Playback Route'
; type=INTEGER,access=rw------,values=1,min=0,max=2,step=0
: values=1

有什么想法吗？
