The Fedora system produces sound with, hard to describe, some "stuttering".  So, it gives the impression of clicks, but there aren't any.
I wonder if that's a buffering or a sample rate conversion issue.  For instance, if one piece of the puzzle decides it's going to convert 44.1 to 48 kHz samples (though it could have just passed it through, as-is) it might introduce noticeable distortions.

OK, I've "fixed" the problem.

I'm using KDE and I went to System Settings-->Hardware-->Audio-->Configure and for the profile for the Bluetooth speaker output I picked
High Fidelity Playback (A2DP Sink, codec ACC)
and now everything is great!

Interesting.  The choices on my system are much less informative.  For AudioEngine 2+
Device Profile:

  * Off
  * Analog Stereo Output
  * Digital Stereo (E958) Output <===
  * Pro Audio

Speaker Placement and Testing

  * AudioEngine 2+  Digital Stereo (E958) <===
  * Build in Audio Analog Stereo

Right now the marked choices are active, the sound is good, and the connection hasn't been dropped for the last day.

Does anyone know what these choices mean?  In particular, what is "Digital Stereo (E958)"?


Maybe the manual for the speaker would have some insight?

FWIW, the manual for mine indicated that " Optimal codec is automatically selected from AAC,
LDAC, and SBC."  LDAC in System Settings was the one causing bad results.

In thinking about it, it sorta sound like talking in front of an electric fan.
I have the same issue as Jonathan, in that all I see are:
            Off
            Analog Stereo Duplex
            Analog Stereo Output
            Analog Stereo Input
But I am running Fedora in a Vmware VM using vmware's built in Audio interface. The device it sees is ES1371/ES1373/Creative Labs CT2518(Audio PCI 64V/128/5200 / Creative CT4810/CT5803/CT5806 [Sound Blaster PCI]. I think that selection came from Pulseaudio as System Settings->Hardware->Audio doesn't provide me with any option to select different Hardware if I want to. I'm using Logitech 7.1 headphones and with these settings usage of the volume control on the headphones is a bit dodgy at times in that it doesn't always actually control the volume. The profile options change if I disconnect the Logitech G533 headphones from the host and connect them to the VM, but I don't get anything like the options that Ed mentioned, but that may also be because Fedora doesn't seem to have direct support for those headphones (at least the last time I looked, and I haven't looked for a while) and Logitech don't provide any interfaces for Linux like they do for windows. Since moving F34 I haven't tried getting my "water fountain" bluetooth speakers working again with the Bluetooth 4.0 dongle as I found it very fiddly to actually get working and the usage of the speakers doesn't warrant the effort in setting it up again.

regards,
Steve
