[Test Case] * Attempt to run jackd and jackdbus, jackd tends to take 100% per CPU * Killing jackd and jackdbus reduces CPU down to nominal levels * Version in Ubuntu Studio Backports PPA does not have this issue, same version exists in Ubuntu Groovy Gorilla. [Regression Potential] * Since jackd is used by multiple professional audio applications and therefore there could be potential negative impact on those applicaitons. * Although that regression potential exists, multiple users have reported great success when using the newer version. [Other Info] * Although not a "bug" per se, upstream developer lamented the fact that the version in 20.04 is so far behind. * Most audio applications and plugins in Ubuntu 20.04 have been developed with this version of Jackd in mind. ---- Original bug report: if jackd and jackdbus run, jackd and/or jackdbus produce high cpu load. jackd tends to take all availabl CPU power bringing the system to slow down remarkably. Killing jackd and jackdbus frees cpu and system load drops from 100%/per CPU down to ~4% overall.
