recently installed CentOS6 on a (quite old) 64-bit system, and from the GNOME’s sound preference app, I can see that the Output volume range is said “amplified” from 63% to 100%. Below 63% it’s unamplified.
No idea what’s implied behind this amplification (I don’t see this on other desktops), but I notice that when “amplified” the sound is pretty bad (at 100% and above, it’s ridiculously bad). Below 63% it’s simply very good and from far, loud enough.
I wonder if there’s a way to make the amplified range (63-100+)
inaccessible? It makes no sense to me to allow the amplified range if it sounds bad (tested with different external speakers).
