蓝牙音频概况
使用蓝牙时有两种不同的音频配置方案,使用哪一个取决于你将如何使用你的耳机以及你如何计划使用它。 "sco" 音频配置是一个低品质、低延时的连接方案。音质近似于无线电话。糟糕的音质在听音乐的时候显得尤为明显。"a2d" 音频配置是一个高品质的压缩连接,并且提供出色的音频品质。截止到2007年7月13日a2d音频驱动无法通过apt获取,而是需要手工编译安装。这是首选的蓝牙音频配置方案。
安装低品质"sco" 音频驱动程序

Loading Prerequisites:
sudo apt-get install bluez-btsco
Loading the btsco module.
sudo modprobe snd-bt-sco Note: If you prefer this module be loaded automatically at boot, run 'gksu gedit /etc/modules' and add a line for 'snd-bt-sco'.
Determine the BT Address of the headset.
- Put the device into "Pairing" mode. This procedure varies by headset, but usually involves holding down the power button for 10-15 seconds.
- Open a terminal and run 'hcitool scan'
""Note: I am using my address '00:07:a4:b8:f9:77' for this example."" ""Please substitute your address from the hcitool scan output for the remaining steps.""
- Look for output like this.
ellie@ellie-laptop:~$ hcitool scan Scanning ... 00:07:A4:B8:F0:77 Motorola HT820 ellie@ellie-laptop:~$
- Edit /etc/bluetooth/hcid.conf (gksu gedit /etc/bluetooth/hcid.conf ) and add a section like this
device 00:07:A4:B8:F9:77 { name "Motorola HT820" auth enable; encrypt enable; }
- Restart Bluetooth services (sudo /etc/init.d/bluetooth restart)
Starting the "sco" driver for the first time.
- Place the Headset into "pairing" mode as above.
- Open a terminal and run 'btsco -v 00:07:a4:b8:f9:77'
- This should cause the gnome bluetooth manager to ask you for a pin number to pair. This is usually 0000 or 1234
Testing the "sco" driver.
aplay -B 1000000 -D plughw:Headset /usr/share/sounds/login.wav You should hear the Ubuntu Login sound.
Configuring btsco to run automatically at each boot.
- Open System -> Preferences -> Sessions and select "startup Programs"
- Click New.
- Enter "BT Sco Headset audio" for the Name.
- Enter '/usr/bin/btsco -r -f 00:07:a4:b8:f9:77'
- Click Ok and Apply
Setting the headset as your default alsa audio device.
asoundconf set-default-card Headset This will create the appropriate entries in your .asoundrc file. This setting is per-user.
Installing High quality "a2d" audio drivers
See [new build docs] for information on these drivers. There is a bluetooth-alsa package in the testing Debian apt repository, perhaps we can port it for gutsy?
Troubleshooting
The BluetoothSkype; page has additional information for configuring the new driver. See [Contact/troubleshooting] for troubleshooting information.
