Bluetooth headset cannot maintain audio integration

With GNOME (pulseaudio), my Bluetooth headsets cannot seem to maintain their connection to the sound input/output. Upon connection, the PC will be able to send and receive sound for a couple of seconds, but then that ability ceases. The Bluetooth connection will remain, but my PC will not send or receive sound to the headset, even though I can select the device in the Sound configuration.

I believe I remember that upon first installation, my Bluetooth audio did not have this problem, but only after attempting to use Google Hangouts with Firefox for a voice conversation that ended up consuming all of my system’s memory, this problem has emerged. This leads me to believe that some vestigial configuration is hiding somewhere, but I can’t seem to find where I might need to look.

I use a Bluetooth mouse with no problems and the Bluetooth connections themselves don’t seem to exhibit any issues, just the integration with the session’s audio.

Device (I think it resides with the WiFi card):

02:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)
02:00.0 0280: 168c:0034 (rev 01)

Bluetooth is shown with:

Unless my Bluetooth radio does not reside on USB, right? I don’t see anything that looks like a Bluetooth chip:

Just in case the following is relevant here…
https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Bluetooth

Bluetooth headset replay problems Some user reports huge delays or even no sound when the Bluetooth connection does not send any data. This is due to the module-suspend-on-idle module, which automatically suspends sinks/sources on idle. As this can cause problems with headset, the responsible module can be deactivated.
To disable loading of the module-suspend-on-idle module, comment out the following line in the configuration file in use (~/.config/pulse/default.pa or /etc/pulse/default.pa):
~/.config/pulse/default.pa ### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
Finally restart PulseAudio to apply the changes.

This seems to have solved the issue. I was looking throughout the Bluetooth sections to troubleshoot it from that angle, but didn’t look through PulseAudio troubleshooting. Thanks!

Glad to have been of guidance.
