Background Music

I have exactly the same problem as Lucubration. I installed a previous version 1 year ago, and since then (beginning at some point) MacOS 11.x on Macbook Pro just started reducing the volume down to like 50% or so of the intended volume. The volume slider stays at 100%. This happens with all applications including MacOS Sound Settings menu. Yesterday I suspected this program might be the problem (since I've done EVERYTHING else other than reinstall the OS.) I updated to 4.0, and that didn't change the problem. Then I grabbed the source code and ran the uninstall script, rebooted, and the problem persists. I have to unplug and replug headphones to fix the problem, and then instantly the problem begins again gradually reducing the volume. It can't just be a coincidence that Lucubration has the same issue. This basically makes my Mac unusable (was using for home entertainment....)

The previous version (0.3.2) worked for me in Mavericks (macOS 10.9.5); the main "problem" was the humongous icon that stuck down from the screen-top menu bar and couldn't be removed. (Never saw anything that intrusive or hideous before!) But the program itself worked. It wouldn't launch in High Sierra (macOS 10.13.6) at all, not even enough to "Update" the program… so I went through their uninstall procedure as detailed on the developer's pages on GitHub, then downloaded & reinstalled the newest version (0.4.0), following all the instructions very carefully... and it STILL won't launch at all. Total waste of my time! I still have the problem that audio in all my web browsers (such as accompanying a YouTube video, etc.) plays much, much softer than the Mac's system volume or iTunes does. Still have no idea why, and with this "Background Music" app non-functional, no idea of a solution. Any ideas? Thank you.

Love this app! Simple and easy to use, does everything I needed it to and even helped me with quiet movie files on my old MacBook. In comparison to similar apps costing over 50$, this is stellar. I use it with XCode 12.4 on Catalina. Go to the GitHub if there are any problems; the explanation there is straight forward.

Good app, but doesn't work with Microsoft Teams

Really cool, easy-to-use interface -- but moving the sliders has absolutely no effect on volume under Catalina

I found this app very useful and effective, but it does not seem to work with Big Sur.

Cool app, but doesn't work with some application e.g. microsoft teams.

This app did not work for me at all. :/

Think this app is amazing how does it not have any reviews? I have already downloaded it a couple times doing fresh installs to my mac.

BGM downloads, but just gives a zip which when opened shows a lot of files, I couldn't open Install manual as it required more s/w
