alt Hacker NewsMy favourite bad volume control was in Real Player around 1997 where changing the volume in the application actually changed the global volume of Windows.

I was so confused by the CD drives of that era. They all had a volume wheel and a headphone jack, but never once did I experience those working. The audio CDs were always “owned” by the OS, which piped the audio through the normal channels out my speakers or the PC headphone jack.
I imagine the existence of those means that CD drives had their own DAC and other logic. I guess there was an idea of wanting to play CD audio without it being a PC concern? Or on PCs without audio capability?
I feel like that was super common. Apart from changing the volumes of entire channels (e.g. changing the level of Line In vs. digital sound), volume was a relatively “global” thing.
And I’m not sure if that was still the case in 1997, but most likely changing the volume of digital sound meant the CPU having to process the samples in realtime. Now on one hand, that’s probably dwarfed by what the CPU had to do for decompressing the video. On the other hand, if you’re already starved for CPU time…
That was a hardware/software thing as far as I remember. If it was using something like DirectSound it would adjust the audio independently. Other media players did the same thing.
It's funny because Microsoft Teams does this today, in 2026.
