Error creating sf::SoundBuffer

[krab]

I get a memory error when trying to create a sf::SoundBuffer:

Code: [Select]

Cannot lock down 82274202 byte memory area (Cannot allocate memory)
Cannot lock down 82274202 byte memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/5)(1: Operation not permitted)
JackClient::AcquireSelfRealTime error

That's before I try to load from a file. It even happens when this is the only code:

Code: [Select]

sf::SoundBuffer buf;
Besides this problem, I've been trying to understand why SFML uses jack server to output audio, but I can't find any useful information on that topic (I use Ubuntu 17.10)

SFML uses the default ouput device. If you set it to Jack server it will use that and it doesn't seem to be configured correctly or SFML may simply not be fully compatible with Jack (or the other way around).
