Using Ubuntu low latency & real time kernels

[Snoopy8]

Had an initial look at the tweaking options and they are not compatible with CPUset, and less friendly. 

My CPUset journey has been posted here

However, I have come back to using the SO simple  version. Perhaps it is time to drop CPUset? 

Using pre-empt=full, nohz_full on CPUs dedicated to the music player and proper IRQ affinity settings (dedicate a CPU for the music output IRQ, shift other IRQS to other CPUs ) could potentially make SO sound even better.   Ideally, SO should hide the complexity of setting this up, providing options to: 

• enable RT kernel (using Ubuntu Pro)
  
• Dedicate CPU(s) to music player
