Thanks Corona,

The system normally has about 180 processes active but despite this the processor utilisation rarely exceeds 30% to 40% of which rhythmbox is only a few percent. Rhythmbox works except that every 30 seconds to one minute the sound "glitches".

I have spent a considerable amount of time eliminating/fixing other issues with it and am now left with this residue of infrequent glitches. My current working hypothesis is that occasionally the demands of some other process briefly blocks rhythmbox from the processor causing a buffer underrun. This hypothesis is supported by the fact that on the significantly more powerful processor there is no glitching.

On the basis that the processing demands of Rhythmbox are slight and that it's probably the most time-critical application running, I thought it might be instructive to see what a higher priority might achieve.

tldnr; I'm not really using it as a go faster button, I'm hoping it will be a latency reduction mechanism.
