Public bug reported:
This problem seems to occur on every device that uses the BCM20702A0
Bluetooth hardware.
How to reproduce:
(1) Pair a bluetooth headset with a machine equipped with a BCM20702A0.
(2) Activate the device. Usually there is a button on the headset you should
press to notify the bluetooth stack that you're ready to use the device. This
creates SCO link and the plumbs the audio components.
(3) Open the sound settings tool and select the bluetooth device under the
"Input" and "Output" tabs. Under each tab you should see a table with an entry
that has a headset icon on the left with the bluetooth device name to the
right. This is the item to select.
Now, everything should be configured so that you can use your bluetooth
device to hear and record audio. Test this by:
Testing Input:
(1) In the sound settings tool, select the "Input" tab.
(2) Make sure the "Input Volume" is not muted and the scale widget is not set
to zero.
(3) Make sounds into the headset mic -- you should see the "Input Level" bar
raise.
Testing Output:
In the same program:
(1) Select the "Hardware" tab.
(2) In the box labeled "Choose a device to configure", select your bluetooth
device.
(3) A combobox should appear at the bottom of the window labeled, "Settings for
the selected device". Choose "Telephony Duplex (HSP/HFP).
(4) Now click on the "Test Speakers" button to the right.
(5) Run speaker test. You should hear a sound.
