> You said you get an xrun after 20 fragments?
I checked my IRQs. Indeed, my SBLive was using the same IRQ as my network card.
I changed
and now the xruns is almost gone. Only some of then in the begging of process.
When running as
root ( so, when get RTC privilegies), they are completely gone.

I am not sure if a diskstream is a good idea, really. I implemented a ring
buffer in MustuxAudioFileFormats::OggFile
in order to get a constant bandwith when reading an ogg. It worked fine, as a
diskstream would do, but
it generates too much sync problems.
I am almost sure the xrun problems is just a low latency matter. As soon as I
get my kernel patched, I will be
sure. Also, I studied many codes from many audio applications, and everybody
put the xruns problems as a
low latency problem, tipical in linux kernel.
