{{Translation}} {{From|https://help.ubuntu.com/community/BluetoothAudio}} {{Languages|UbuntuHelp:BluetoothAudio}} = 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 === 注意:原作者已经停止维护此软件 <br> ===== 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 [[http://bluetooth-alsa.sf.net/build.html 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 [[UbuntuHelp:BluetoothSkype|BluetoothSkype]]; page has additional information for configuring the new driver. See [[http://bluetooth-alsa.sf.net/contact.html Contact/troubleshooting]] for troubleshooting information. ---- [[Category:CategoryBluetooth]] [[Category:CategoryAudio]] [[Category:UbuntuHelp]]
