Player Gain settings

[UKenGB]

In a Player's DSP settings, Gain can be set separately for 'Input' and 'Output'. What's the difference?

I understand the technical difference of course, but in practical terms, what effect would one have compared to the other? If one wants to increase a Player's basic volume, which Gain would be best to use?

"Input" is applied before the EQ, while "Output" is applied after them.
Both are mathematically identical here since the only kind of filters we support at the moment are Equalizers.
I always use "Input" myself.

But keep in mind that increasing volume in software will have an effect on the sound quality, it won't be clipping if you keep the (by default enabled) limiter on, but it will still compress louder sounds.

I am using a couple of Lenovo ThinkSmart View devices and they play rather low (when they play at all, but that's a different issue). Plus the Mini Media Player's volume slider is partially broken and the TSVs have physical volume buttons. So I was going to increase the gain of the stream a little, set the media player's volume at max (or close to) and not show it on the screen, so relying on just the physical buttons which are much easier to use if truth be told.

So I would not be massively increasing the gain, just to juggle settings for a suitable volume range achieved with the buttons.
