I am using Jitsi in//on the browser [for me, Firefox].
I don't know if I have a preference as I have only "just started using" the past few months via being given a link I click on whilst I am on my laptop... so unfortunately I cannot speak about Jitsi via Desktop Version at this time.

Besides simple sound volume off of my OS//headphones, I use whatever the default settings are.
> 1-1 meetings or 3+ group calls?
Group calls, each time would be roughly 5-12 people.
For other info just for giggles:
The laptop I do this on is connected wirelessly to my home wireless network, about 6 feet away from my wireless router; my wireless router may have multiple people using it at a given time since I share. I'm in US-California-Silicon_Valley on Comcast.
Are there settings you adjusted?
Are you just doing one-on-one meetings (that works fine for me too) or group calls of 3+ (which is what I need to do everyday where it immediately becomes unusable)?
I'm also using a linux distro based off ubuntu/debian.
