Here ogg123 just never skips on an older 750 MHz box, which is 4-5 times slower than your 2GHz box - while i have _fourty nice-0 infinite loops_ running. I.e. at this clearly ridiculous load, at just 2.5% of CPU time ogg123 is just chugging along nicely and never leaves out a beat. i'll try to figure out what is happening on your box. I asked for your .config off-list (which you already sent me) and i'll try to reproduce your problems. One thing i noticed: when ogg123 plays with 'esd' also running on the system, it starts skipping really badly - but it does so under all schedulers i tried (cfs, sd, vanilla). Ingo
