How do users upload audio?

I have just installed the stock Jamroom 5.2.37 core. When I log in as a user I cannot upload any audio, the option is not there.
I have trawled google & jamroom website & found thread about Quotas. So I have set up a quota for artists & moved user profiles to it but still the users have no button on their profile to allow them to upload audio.
What is wrong?

Hi - Welcome to Jamroom.
To upload audio you will need to purchase, download and install the Audio module - https://www.jamroom.net/the-jamroom-network/networkmarket/12/audio-support
This is easiest done by setting up the Marketplace module on your install - ACP=> Core=> Marketplace=> Tools=> Marketplace Systems. Click on the Modify button and enter your email and Marketplace ID. These are found in your profile here - https://www.jamroom.net/peepo - Update(gear wheel icon)=> Licenses
Once this is done you can install modules directly from your site via the Marketplace module - ACP=> Core=> Marketplace

From this and your other post its obvious you are new to Jamroom so I would recommend spending a bit of time reading the documentation and maybe checking out our free video course - https://www.udemy.com/start-your-own-online-community - Hopefully it'll help you understand how Jamroom works and you see how easy it is to use and set up.
Hope that helps
Paul
