For people who asked me if the new Raspbian Stretch changes anything here, yes, the new Raspbian brings Pulse. Audio v. 10 but not installed by default, thats not all, Raspberry Pi Foundation chose to go back to ALSA and use Bluez alsa module. Ill write soon a post to explain that, but as far as I see, this is not resolving the main problem that is Bluetooth microphone input, this needs to be solved in the BCM chip firmware, to be continuedIf you are here, it means that you are trying to use your headsets microphone AND speakers with Raspberry Pi 3. What appeared to be a configuration issue turned to a real headache. After so many weekends spent to find a solution, I ended up with a lot of information and no workaround, a sort of puzzle parts that Im still collecting over all Google results, Im not exaggerating if I tell you that I already read every single page that Google can propose for this topic. I keep my previous post for history not anymore updated http youness. With all that effort, I start to have clear idea of the problem. So here you will save your time and focus on the major root cause. Long story short The real problem comes from built in Wi. Fi Bluetooth chipset BCM4. How do I know it Because I used external Bluetooth transceiver USB dongle, and now my headset works perfectly AD2. P HSPSo, unless I find THE ideal solution, you have no choice but to use Bluetooth USB dongle. I know that some people may just want to know how to do, and dont care about details, so Ill explain first how to make it. Then Ill post exhaustive story behind this BluetoothRaspberry Pi issue, in order to help others who want to explore more. HOW TO DOStep 1 Pulse. Audio. One problem that is mentioned everywhere is the drop out of Bluetooth support by ALSA. Now only way is Pulse. Audio. Source https git. Minimal versions needed for HSP A2. DP included are Bluez 5 Pulse. Audio 6. Source https www. SoftwarePulse. AudioNotes6. I recommend to start  with fresh Raspbian Jessie image https www. Update and upgrade it sudo apt get updatesudo apt get upgradesudo apt get autoremovesudo reboot. Check the version of packages dpkg l bluez. Version 5. 2. 3 2rpi. Version 5. 0 1. WARNING Raspbian repository is still using Pulse. Audio 5. Purge pre installed Pulse. Audio sudo apt get purge pulseaudio. To install manually Pulse. Audio 6 or upper, there are two methods and both of them are OK. Method 1 Install Pulse. Audio from Debian Backports. Edit source list sudo nano etcaptsources. Add the line deb http ftp. Add PGP keys to your Raspberry Pi gpg keyserver pgpkeys. B4. 8AD6. 24. 69. D0. 44. 2B9. 0D0. B4. 8AD6. 24. 69. D0. 44. 2B9. 0D0. Update package list sudo apt get update. Install Pulse. Audio and its Bluetooth module sudo apt get t jessie backports install pulseaudio pulseaudio module bluetooth. Check the version 6 or upper is OK dpkg l pulseaudio pulseaudio module bluetoothii  pulseaudio             7. You can jump directly to Step 2. Method 2 Use Pulse. Audio sources. Download the sources from Freedesktop. Unzip and go to the directory tar xvf pulseaudio 6. Run bootstrap script. I will sum up here all errors I encountered in case people search them by copypaste. Unable to find libltdl version 2. Makes sure you have libtool 2. Use without caps to disable capabilities support. No package json c found. No package sndfile found. So install all above libraries sudo apt get install intltool libtool libcap dev libjson. The script should now ends correctly, and in the command line you can see a table of the configuration done, with enableddisabled parts. On my side udev, bluez. X1. 1, systemd, were not enabled, so I installed additional libraries sudo apt get install libudev dev libsbc dev libbluetooth dev libx. Re do the. bootstrap, now missing parts are enabled. Then, make and install Pulse. Audio this will take some time, take a coffee. The last command to avoid some errors of shared libs not found. Step 2 Bluetooth Hardware. To turn off built in Bluetooth controller BCM4. Add lines blacklist btbcmblacklist hciuart. CTRLX, then Y, then Enter. Reboot sudo reboot. Now connect your Bluetooth USB dongle, mine is ASUS BT4. At this step, the result may differ, maybe your USB dongle is already supported by RaspbianFor ASUS BT 4. I have to install manually the firmware. To know if your hardware is correctly called, check it here dmesg grep i bluetooth. In my case I see the error 1. Direct firmware load for brcmBCM2. A1 0b. 05 1. 7cb. Here I need to explain some things. The chipset in USB dongle is from Broadcom BCMBroadcoms firmwares are proprietary, it means that they arent shared as open source, and some times not in Linux repositories. So to use it, you have to find corresponding. Easy way is to download ASUS drivers online wget http dlcdnet. ASUSwirelessUSB BT4. UTUSBBT4. 006. P homepiDownloadsUnzip it sudo apt get install zipcd homepiDownloadsunzip UTUSBBT4. Open. inf file of the drivers and look for ASUScd BTW6. Win. 7USBASUSWin. Search for the driver supporting your hardware. For ASUS BT4. 00 I find the corresponding file BCM2. A10. 01. 0. 02. 0. Not that it is. hex, so I need to convert it to. Ill use hex. 2hcd tool cd homepiDesktopsudo apt get install gitgit clone https github. Here I meet error due to Raspberry Pi configurationgcc O2 marchnative hex. Error in gcc double free or corruption top 0x. Abortedso I modify the Makefile sudo nano Makefile. Replace the line CFLAGS O2 marchnative. By. CFLAGS mcpucortex a. Source https www. Tomb Raider Trilogy Eboot 3.55 there. Redo make command, now you have the executable hex. DownloadsBTW6. 5. Win. 7USBASUSWin. BCM2. 07. 02. A10. Desktophex. 2hcd. BCM2. 07. 02. A10. BCM2. 07. 02. A1 0b. Pay attention here to the name of. Copy it to firmware folder, reboot, and check Bluetooth initiation sudo cp BCM2. A1 0b. 05 1. 7cb. The firmware should be correctly called now Now we will connect the Bluetooth headset same steps as for A2. DP only postStart Bluetoothctl tool and initiate everything bluetoothctlpower onagent ondefault agent. Turn on the headset, for mine I press and hold the button till I see white blinking LED. Start the scan scan on. After some seconds, you will see the headset name and MAC address xx xx xx xx xx xxPair, trust and connect it pair xx xx xx xx xx xxtrust xx xx xx xx xx xxconnect xx xx xx xx xx xx. Now the headset is correctly connected to the Raspberry Pi. If not, it should be Pulse. Audio daemon that it is not already running. Open new console and start it pulseaudio start. Go back to the other console and connect again the headset connect xx xx xx xx xx xx. Now the headset is connected Check cards in Pulse. Audio pactl list cards. You can see the Bluetooth card, and the profiles A2. DP and HSP available. For me the default profile was headsetheadunit, if it is not for you, force it pacmd set card profile 1 headsetheadunit. Tell Pulse. Audio to use the headset as default sink and source pacmd set default sink bluezsink. Record yourself with the microphone parecord v voice. CTRLC to end it. Play it back paplay v voice. Are you listening to your voice Final check that A2. DP is also working, activate it pacmd set card profile 1 a. Your voice again, thats all.
