我刚刚切换到 ubuntu 15.10，遇到了一个非常烦人的错误。当我将耳机（Betron BT1050）连接到笔记本电脑时，它只能作为单声道设备连接，当我尝试切换配置文件时，它无法连接到 Blueman 和 Pulse 音频（脉冲音频会更改它，但没有效果，它会自动重置为 HFP），它说这是不可能的。说了这么多，我必须说，我让它正常工作了两次，两次都是在文件中更改了一些内容之后audio.conf，但断开连接并重新连接后，它再次连接到单声道设备。我的audio.conf文件看起来像这样，这是我在网上找到的（当我第一次打开它时，什么都没有）：
` # 音频服务的配置文件
# This section contains options which are not specific to any
# particular interface
[General]
Disable=Headset (according to a guy online this way the device will connect as a A2DP and first time it worked)
# Switch to master role for incoming connections (defaults to true)
#Master=true
# If we want to disable support for specific services
# Defaults to supporting all implemented services
#Disable=Gateway,Source,Socket
Enable=Gateway,Source
Enable=Source,Sink,Headset,Gateway,Control,Media
Disable=Socket
# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
#SCORouting=PCM
# Automatically connect both A2DP and HFP/HSP profiles for incoming
# connections. Some headsets that support both profiles will only connect the
# other one automatically so the default setting of true is usually a good
# idea.
AutoConnect=True
# Headset interface specific options (i.e. options which affect how the audio
# service interacts with remote headset devices)
[Headset]
# Set to true to support HFP, false means only HSP is supported
# Defaults to true
HFP=false
# Maximum number of connected HSP/HFP devices per adapter. Defaults to 1
MaxConnected=1
# Set to true to enable use of fast connectable mode (faster page scanning)
# for HFP when incoming call starts. Default settings are restored after
# call is answered or rejected. Page scan interval is much shorter and page
# scan type changed to interlaced. Such allows faster connection initiated
# by a headset.
FastConnectable=false
# Just an example of potential config options for the other interfaces
[A2DP]
SBCSources=1
MPEG12Sources=0
我知道很多人都经历过这种情况，有些人可能有解决办法。你有什么解决方法吗？
谢谢
