After the upgrade to version 7.25 (around April 2016) of Skype for MacOS, the ability to change the conversation volume in a way **independent from the system volume** seems to have been removed. To be clear, I am referring to the ability to change a Skype conversation audio volume, while leaving the System volume unchanged, so that System's sounds and other applications sounds stay the same.

In the past versions this was done via two entries in "Conversations" menu, or via the two keyboard shortcuts cmd-alt-up\_arrow and cmd-alt-down\_arrow.

Is there a way to have that functionality back?
