Does too much acid cause burping?

I’ve heard a lot about how low stomach acid can cause indigestion, which in turn causes gas build-up in the stomach.

However, lately I’ve been having A LOT of gas (burping constantly, even before I eat anything). When I tried to take HCL Betaine supplements, the burping got worse instead of better. Is it possible the burping / gas could be caused by too much acid? And that I made it worse by adding more acid to it (with the HCL supplement)?
