I uninstalled BAE completely and checked that there were no pipeline devices in the device manager. The machine was rebooted.

System Information
Edition: Windows 11 Pro N 64 bit
Version: 21H2

On a new installation:
BreakawayPipeline_installer_4.66_2.exe installed fine, and seems to run fine, except that there is no sound output.
Breakaway_setup_1.44.00.exe installed without errors but crashed on any attempt to start it up. There were breakaway.exe.<number>.dmp files in the Local\CrashDumps folder with the following information in Visual Studio:

I have been using Breakaway Audio Enhancer since 2012. I always make sure my default audio device is Breakaway Pipeline. Before I purchased DELL AC511 USB SoundBar recently, I have been using Breakaway Pipeline -> Realtek HD Audio with no problem. With the new soundbar, while the test tone does play well in Breakaway Audio Setup Wizard: Step 1, I can only hear a very soft-volume test tone elsewhere, including Setup Wizard: Step 2 after a successful test in Step 1, and in expert mode with Output set to DELL AC511 USB SoundBar and all kind of parameters (KS, DS, Wave, etc). Like I said before, under the expert mode of the Setup Wizard, the output is explicitly set to DELL AC511 USB SoundBar and the test tone actually plays through Realtek in very soft volume.

I am inclined to say there is a software issue in Breakaway Audio Enhancer. In a few days, when the opportunity comes up, I will try uninstalling BAE and reinstalling it.

Ok. I think I have tried everything reasonable.

I have tried KS, DS, and Wave for the expert mode Interface making sure the Audio Device always points to my DELL AC511 USB SoundBar, which is listed as one of the available devices. My default sound device points to Line 1 (Breakaway Pipeline) which has been directed to my DELL AC511 USB SoundBar in the expert mode. But I can only hear a low-volume audio playback through my laptop audio device Realtek HD Audio output and not my DELL AC511 USB SoundBar.

I thought the laptop audio device could be causing a problem, so I also tried disabling my laptop audio device Realtek HD Audio output in the device manager and rebooting my laptop; but to my surprise, I could still hear the same low-volume audio playback through my laptop audio device Realtek HD Audio output (even though it has been disabled in the device manager). Breakaway Audio Enhancer still lists Realtek HD Audio output as available even though it has been disabled in the device manager and after a system reboot.
