There are two different Audio profiles implemented in Bluetooth, which one to use depends on how you will use your headset and how you plan to use it. The "sco" audio profile is a low quality, low latency connection. The sound quality is comparable to a cell phone. The poor sound quality is very noticeable when listening to music. The "a2d" audio profile is a high quality compressed connection, and provides excellent audio quality. As of July 13, 2007 the a2d audio driver is not available via apt, and requires manual compiling for installation. This is the preferred audio configuration for Bluetooth.

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。

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.
  1. Put the device into "Pairing" mode. This procedure varies by headset, but usually involves holding down the power button for 10-15 seconds.
  2. 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.""

  1. Look for output like this.

ellie@ellie-laptop:~$ hcitool scan Scanning ... 00:07:A4:B8:F0:77 Motorola HT820 ellie@ellie-laptop:~$

  1. 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; }

  1. Restart Bluetooth services (sudo /etc/init.d/bluetooth restart)
Starting the "sco" driver for the first time.
  1. Place the Headset into "pairing" mode as above.
  2. Open a terminal and run 'btsco -v 00:07:a4:b8:f9:77'
  3. 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.
  1. Open System -> Preferences -> Sessions and select "startup Programs"
  2. Click New.
  3. Enter "BT Sco Headset audio" for the Name.
  4. Enter '/usr/bin/btsco -r -f 00:07:a4:b8:f9:77'
  5. 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.
